LOGGER Libraries

Many libraries are installed, perhaps some are a consequence of the installation of other libraries or part of the Arduino world. This list shows libraries have been intentionally installed and that the library manager shows as installed. Built in libraries are not listed. Intentional installations in this list are listed with the library revision that was current at the historical point when the the library was added and/or the code was validated. Revision numbers in this list may not be current. Updates to these libraries are shown in the source control revision history below. Libraries installed but used only for other projects are listed in case there is an interaction.

Changes
20200619 Not logged in

Move millisecond time wraparound to services loop. Integrate it with delayed reboot that allows a web request to perform a task to get an ACK page displayed before the reboot occurs. Move reboot notification after button processing so ACK of button press shows the ACK message. Delay reboots by REBOOT_DELAY in all cases.

Rename webStartPage to webservicesStartPage. Make sure all cases do alerts. Rename webEndPage to webservicesEndPage.

20200616 Not logged in

Add ALERTS command to read a file of alert bindings. Add the concept of a valid range for various sensor types. If the sensor is out of range send an alert to the user typically by email. Other alert types are proposed. The entire history of alert bindings is kept in the file on the SD card. As they are read the latest binding overrides all previous bindings. The bindings are read at boot time.

Change how ONEWIRE command works it now accepts the conversion delay and not just a flag as an argument. Increase normal conversion time to 1 second from 750 ms. Looking for why Temperature_0 is always hot. Another onewire device in the same location also shows hotter than ambient. Add more messages when debugMessageLevel is high.

Rename the GETNTP command to NTPGETTIME.

Add PHISTORY command to read parameter history file. Save parameter changes to a history file. If parameters are not recovered from flash read the history file to set them.

Add the concept of user names for sensors. Save and recover at boot these name bindings in a file on the SD card.

Fix a bug in how the SD card is found on old cards. The bug caused the SD card to be missing on every other boot. Rework code to find the SD card on startup. An automatic reboot may happen if the SD card is searched on the old pins on a new board. This only happens after errors or if the SD card ID code fails to find the card at startup. (Possible if the card was missing last time.)

Rename the flag in the startup code that always turns on Access point mode.

Update M2X comments now that it is missing.

Update device ID support for most devices to have a print flag.

Rework the format of the parameter table.

Fix a bug in temperature conversion to degrees F in graphs.

Convert some code to common subroutines in support of changes to establish, save and restore a band of minimum and maximum values for a sensor. Report those values as part of the class. Add printout of min and max values to the table dump of the sensor class. Add setting min and max values to the class. Rework printout code to support setting these values as part of the sensor settings.

Fix nameing of service to print fixed point numbers. Fix stringToLong to work on 32 bit numbers. Expose fixed point printing service and hex printing service.

Fix most web page header printouts to report issues and errors.

Make tinme change reporting quieter unless debugMessageLevel is higher.

20200529 Not logged in

Rework firmware update. Callbacks now available. Reporting of sucess and failure is improved. Two version numbers are created for testing other than the version number these are the same code.

Reconfigure the chart area to get time axis headings to display.

A history of parameter (permanent variable) settings is saved to a file as well as to permament memory. Only the users variables are saved. These will be recovered from the file if reading them from memory fails. In this way the users configuration follows the SD card if that card is moved to new hardware. This also takes care of the intermittent failure to read the parameters from memory.

Increase network timeout to 2000 in hope that will allow code download on a lower quality link.

20200522 Not logged in

Completed email alert system. Time between emails is a new field on several pages.

Add yields when reading files from the SD card. A yield is performed after reading each line. Time history, name history and alert history are all updated.

Add services to emit a sensor name and value to a string.

Suppress NTP time adjustment printout unless debugMessageLevel is elevated.

Web page argument handling is centralized for application specific page arguments and added to all application specific pages. This is the same basic method as has been used for page arguments that are handled by the non-application specific webservices. User warnings generated by webAlertIssues are added to a few pages that did not have them (missing database etc.).

20200520 Not logged in

Install esp8266 version 2.7.1 replacing 2.6.3.

Add controls and web pages for setting alert ranges. Email messages are not sent yet. This adds the ALERTS command. Read the alert ranges (and eventually email configuration) from a file at startup. Add upper and lower limit values to sensors.

Improve initial temperature handling, especially how onewire temperature is reported before the first sample is completed.

Add some services for reading and reporting HEX values. Also for fixed point numbers.

Improve control of Onewire debugging messages.

If a time adjustment can not be written to the history file do not keep trying. The retry happens when the SD card is missing.

Rename the GETNTPTIME command to NTPGETTIME.

20200518 Not logged in

Improve formating of STATUS command output.

Improve messages associated with not finding the SD card. Change the checking protocol for finding the SD card to automatically detect old vs new pinning and prevent continuous crashes when old pinning is selected on hardware with new pinning. Code that intereacts with the SD card now quietly handles a system where the card is not inserted.

Reporting of reboot reasons for software induced reboots did not catch all cases of these and reported some as reboots due to a bug or crash.

A failure to log a NTP clock time adjustment resulted in continuous messages when the SD card was missing. This message is now emitted only once.

The XML history example is now a live link instead of just simple text.

20200516 Not logged in

Add the concept of a user name for a sensor. These names are logged in a side file on the SD card in a way that post analysis could show what name was in use when a sample was taken. The USER_NAME command is added to test the internal support for this feature. The feature is seen on the Sensor Configuration page.

A test command 'LED' to turn the built in LED on and off is added.

Off by one errors that caused inaccurate sampling time when not sleeping are fixed. The bug was introduced with the sleep code.

Reset of the I2C bus is integrated with the I2C code. A bus reset function is added and used in the I2C code. The reset must still be coordinated with the I/O power code because powering on I2C chips without proper reset can cause latchup. The code to support this is moved around, but, it still works the same way. The I2C reset routine now calls the power code. Other I2C code calls the reset code. The power code must still always do an I2C reset.

M2X code now aborts without putting data on web pages if off. AT&T no longer supports M2X.

Names of some networkservices routines now follow the module naming convention.

Security checks are updated to allow pages to display differently when writing is not allowed (signature not given). This is used on the Sensor Configuration page as part of user names for a sensor.

Table row framing is moved out of the low level Sensor print code. The caller is now responsible for row framing. The sensor print just puts out the TD fields of the row.

Some disabled debug code is put under DEBUG_LEVEL control rather than being completely turned off.

The Access Point name is displayed on the system status panel.

The frequency of NTP time logs in the time history is reduced. One occurs at each non-sleeping boot. Small adjustments may not be logged.

20200511 Not logged in

Log when time is set to keep a record that allows database fixup. Setting time from the database is always logged. Setting time from other sources is logged if the other source is of high quality and a low quality log happened. There is no need to log high quality times if one already happened. The DB_TIME_SET command is added to test and support this. A timehistory web page is added.

Fix bugs associated with multiple files to read/write and improve logic to save space in the namehistory code.

Handle some fringe cases in taking samples and starting to sleep where negative time in MS was not being compared correctly and resulting in a failure to sleep.

Reboot on MS timer wraparound. This is every 24 days.

When entering deep sleep use the lowest power RF_DISABLED wakeup mode.

Improve messages for the DEBUG command.

20200510 Not logged in

Some change in a prior release caused pulse counting pin pulses to cause a crash. This is fixed by conditioning the SCL and SDA pins to be input types in the ISR. The problem caused a panic in a yield call, probably by the Wire code fixing or handling an error condition.

Fix DEBUG command so it can set level 0.

Add support for dynamic adjustment of microsecond to millisecond ratio. Reduce jitter allowed to 2 seconds.

Repair formatting of pin changes messages.

Allow longer delays in network setup and search for networks.

Improve reports associate with edge sensitive device detection.

Deep sleep for network startup checks hardware startup state rather than the software shutdown flag.

20200508 Not logged in

Add DEBUG command to control debugging output. Many changes to control messages. This works in cooperation with the DEBUG_LEVEL macros which now only enable and disable code. Which outputs are emitted are now controlled by the DEBUG command. The setting of the debugMessageLevel is stored permanently. Remove the VERBOSE command, this replaces that function.

Add DEEP_SLEEP command to test deep sleep mode.

Control output pin state prior to deep sleep. Add code to put pins in a low power state that can be used even if not sleeping.

Add reports for the status of the flash database. Control them based on the DEBUG command.

Improve handling of GPS sentences and how they report time adjustments. GPS sentence parsing is lightly tested.

Add reports of the previous I/O power status to the POWER command.

Change the database header to use tenth seconds to measure time between samples. The old version used milliseconds and stored the value in 16 bits. Both database type are recognized and using an old database is safe. the DATABASE_MINOR_VERSION is now 4.

Add the capability of deep sleeping between samples. When this is enable web access is no longer available. The device must be power cycled to regain web access. NOTE: pressing the reboot button does not look like a power cycle to the software and will not regain access, this looks the same as a wake from deep sleep to the software. The network and associate web services are not turned on after a deep sleep. If deep sleeping is on after a power cycle the system will stay awake for a while so the user can regain control via normal web activity. Two power cycles may be required. NTP time services are not read when waking from deep sleep, a clock chip is required. Code download controls and prevents deep sleeping for an extended interval.

Completely restructure the dataservices module related to how it decides to take the next sample. Taking samples prior to knowing the time is no longer supported. These changes are in support of the deep sleep capability. Improved debug message handling is part of this change.

Rename the DataBaseState_t enum DatabaseOldVersion to DatabaseBadVersion. Update the debug messages related to it.

Update DEBUG message control for DLVR pressure.

Update DEBUG message control for MAX11615.

Update DEBUG message control for SI7006A20.

Update DEBUG message control for TCA9539.

Update DEBUG message control for MS8607.

Update DEBUG message control for Onewire. Improve clock chip support. Add retries for clock chip communication.

Allow the USB flash device to be controlled by GPIO10 or GPIO16 depending on the processor board version. Automatically detect and remember the board type based on the presence of a clock chip. Old boards can handle the presence of a clock chip so long as the first time the processor board is started the clock chip is not present. The processor notices and remembers this in a permanent variable. If permanent variables are cleared the value of FLASH_SS_PIN may have to be reset manually, 16 for old boards 10 for new.

Rename all flashservices global routines and variables to have the complete prefix in their name.

Record the time to boot (in milliseconds). This is used in deep sleeping.

Counts of unexpected reboots are improved. Deep sleep is not counted as a reboot.

Network startup code is moved to the network module in anticipation of being able to start and stop these services dynamically. That is not yet implemented.

The loggerYield() functions at startup behave differently, not forcing samples out so startup can complete properly.

Add retries to reading permanent variables.

Handle negative times when dumping amounts of time.

Formatting in the version printout is improved.

Web page controls for deep sleep are added. The methods of controling and responding to buttons are improved and are now used for sleeping ON/OFF and temperature units selection. Button background color control is fixed and allows for a selectable color when a button is emitted.

Some potential bugs are fixed due to a failure to wake up for a cycle when a web page controlled value is changed. Wakeup is now set whenever a web page resets and reloads. Performing this task is centralized.

When the used gets a web page sleep is prevented for a time. Currently set to 3 minutes.

Update DS3232RTC to 1.2.12 from 1.2.9

Update library Adafruit Circuit Playground to 1.10.4 from 1.10.3. Notice that the include of SD.H works properly if placed at the top of the module. It also appears that a memory leak when the NTP time server was probed is now fixed.

20200423 Not logged in

Add testing of light and deep sleep. Add support for clock chip periodic interrupts to allow testing of a possible sleep methodology. Also add support for deep sleep (from a web page button) and associated recovery by reboot of the system. This support is still only for testing sleep characteristics. In debug modes control an I/O card output pin as deep sleep is entered for testing.

Add support for the SD card FLASH_SS_PIN to be in different places to free up GPIO16 for deep sleep recovery.

Improve time detection and reporting of test that turns network by holding down the onewire data line.

Increase the NTP time request interval to 4 hours from 1. This is based on observations of how often a real change is needed.

Make some subroutines local to their module which helps Doxygen warnings.

Save some space in non-debug mode by turning off symbolic names for pins.

Add code to stand down the pin states when entering sleep. This will also be a place to put code that stands down I/O devices, but, there is no such code currently required.

Many comment upgrades to reduce Doxygen errors and warnings.

Some additional files added to the backup.

20200417 Not logged in

Upgrade to Arduino 1.8.12.

Add CLOCK_INTERRUPTS command to test clock chip periodic interrupts. This command and the associated support is presently for testing only. It was used to determing that clock chip interrupts can cause a processor reboot which might support deep sleeping. Deep sleep is more likely to be supported by use of ESP features that involve connecting GPIO16 to RST and need another I/O pin (GPIO10 on the ESP-12E).

Improve discussion of element logging that is skipped because time in the database is the same or newer than the time of the element to be logged.

Improve timeout handling for web sending interactions. This eliminates an issue where distant or slow connections got dropouts in pages being presented.

Add pin definitions for GPIO9 and GPIO10. Improve notes about FLASH_SS_PIN for planned change to use GPIO10 for this purpose on the next hardware spin freeing GPIO16 for sleep wakeup code that reboots the processor by connecting GPIO16 to the processor RST pin.

Improve handling of ~DR signals. Most of changes relate to improved error handling and reporting when an additional cycle is required because ~DR stayed on after the first pass. Some cases get postponed until the next cycle with flags set to improve reporting of why postponement happened. An extra read is done to see if the ~DR signal clears on the first cycle or is a real indication of new processing required. Which device address saw changes is reported when pin changes are checked so high level code can take appropriate action and do better logging.

Watch the onewire signal to see if switch SW1 is held down. This is (will be) used as an indication that networking should be turned on for an interval. Incomplete battery handling related to turning on the network and turning it off so sleeping can occur is added. Some battery operation support is added but this support is largely incomplete.

Save a modest amount of code space by keeping pin names in a data table only when debugging is turned on.

Add discussion of sleep modes. Improve discussion of sleep strategy. Add debugging feature that sets I/O pin 16 when shallow sleeping should occur. Add more sleep testing features. Sleep implementation is not complete.

The pins on the AC card used to detect which card is present need a pullup. Drive them high to save power when the pullup is in place. This also prevents multiple ~DR interrupts when the pins are left floating.

Make NTP time services quieter unless debugging is turned on. Improve messages when delta to NTP report is 0.

Change menu to have an Exports section currently populated by the XML page.

Code space report:

Sketch uses 459024 bytes (43%) of program storage space.
Maximum is 1044464 bytes.

Global variables use 44100 bytes (53%) of dynamic memory, leaving 37820 bytes for local variables.
Maximum is 81920 bytes.

Same as 1x67 with different version number to test downloads.

20200309 Not logged in

Revet timeout on WiFiClient to 1000 after parsing header. The short timeout is requred to allow command lines to operate promptly. If the timeout is left short fragments of the web page are lost on slower clients or distant network connections.

20200307 Not logged in

Increase handleClient delay to 1500.

Break up some long lines is number INPUT on web pages.

Report code update errors in some cases.

Add additional yields to sensor reads. Do not do flush of web streams at each yield.

20200306a Not logged in

Add loggerFastYield and call it wherever loggerYield is done wvery N times.

20200306 Not logged in

Change loggerYield to not do a flush.

20200304 Not logged in

Better reporting of NOT_DATA_READY.

Improve sequencing of the OneWire sampling and other uses of the OneWire pin. (for WiFi on period trigger).

Add support for triggering a WiFi network on period. The network is still always on, just the trigger of the on period is implemented.

Shrink the size of some blocks of web page data to the network.

Add additional DEBUG reporting of pin state and pin on periods.

20200207 Not logged in

Install esp8266 version 2.6.3 replacing 2.6.2.

Rework buffering sending partial content to the server. The old method could have gotten errors when only a partial string remained depending on exactly how Stirng.substring worked.

Reformat command table.

Add Data Map page to display the map of the datastructure saved at each sample interval. Move some definitions to independent modules that can be shared with the CHANGER code.

Some space savings in static string allocations.

Make last temperature a signed number.

Better checking if humidity and pressure devices are both present at address 0x40. Add a warning to the user.

Add the concept of named periods.

Add the concept of boolean permanent variables. Use it to add display in degrees F vs degrees C.

20191226 Not logged in

Resolve a number of minor compiler warnings, removes some arguments and some routines. Enable more compiler warnings.

Provide for boolean permanent variables. This still needs to display the choices as a selection of YES or NO as values instead of numbers.

Allow Names for Periods to contain spaces.

Add background colors to Named Period columns.

Move parameter setting from page arguments to a central subroutine. Call page starting routines more uniformly providing for security and button handling. Fixes some non-working REBOOT buttons. Add the concept of parameters resolution that is only allowed when writing is allowed to permit these support routines to be more general.

Provide for content in the EMAIL_TEST command.

Add temperature units of F vs C. Remove a table of unit names in favor of code that emits the name. This allows the names to adjust for the units that change (C vs F).

20191222 Not logged in

Remove use of time.h in favor of timelib.h.

Add Named Periods services and web page. Allowing user to establish a name for a data set.

Add support for the MAX31826 temperature reading. The EEPROM is not supported.

20191220 Not logged in

Recognize the DS28EA000 and treat it as a simple temperature device. Recognize the DS28E07 and properly ignore it as an unrecognized device.

Fix bug in Firmware reload page that ignored the button.

Recognize and ignore several additonal onewire device types.

Convert to non-secure email sending. Now operational and turned on. No alerts configured yet to send messages.

SMTP configuration parameters for email reporting added. Service routine updated to simpler interface.

Rework storage of permanent variable names so they do not consume dynamic data storage.

Secure SMTP sending class removed. It did not work probably due to space conflicts.

Save space in RAM by better String and F() usage. Make command list into a macro. Make pararmeter list into a macro.

Move getField to general purpose services.

Normalize include file names. Fix capitalization.

Install Servo by Michael Margolois 1.1.6 replacing 1.1.5.

20191216 Not logged in

Install Arduino AVR version 1.8.2 replacing 1.8.1.

Install esp8266 version 2.6.2 replacing 2.6.1.

Install Time by Michael Margolois 1.5.0 replacing 1.4.0.

Add test code for sending email. There are issuse with space and security. This test currently disables normal processing it is currently turned off.

Improve use of F() and associated String calls to save space.

20191213 Not logged in

Add web page for reload of firmware.

Many space saving updates by eliminating conversions to String types before calls to subroutines. Some of these improve performance by eliminating the free storage allocation of creating strings. More such optimizations remain.

20191209 Not logged in

Add HANG commmand for testing watchdog reboots.

Formating updates for output.

Rework checking for delays to use more common code, use more static string arguments and to disable more cases unless debugging is turned on.

Add support for the DS2417 and DS2415 time chips. Accept time from a time chip when it is available on startup. Rework onewire code to allow for chips that do not supply a CRC with their data. (This code is now tested.)

Add user visible reports of too many onewire devices seen.

Report changes in stored parameters only when there is a differnce.

Detect reboot causes better. Note reboots due to system power up and count unexpected reboots independently from power on reboots our update reboots. Report more reboot type information.

Remove underline decorations from menu items. Rework some menu formatting.

Add UPDATE command to update from a Binary file on the Dragonnorth server. Web page support not yet available.

Install Adafruit Circuit Playground version 1.10.3. replacing 1.10.2.

20191121 Not logged in

Install Adafruit Circuit Playground version 1.10.2 replacing 1.10.1. Install esp8266 board version 2.6.1 replacing 2.5.2.

Update routines that check for delay to use constant ROM string arguments. Rename a number of these routines to use different names based on argument type. Find a bug with the inclusion of the SD.h library that caused conversion to dynamic strings at the call to the time routines.

Change web page output to include CR LF after each block of HTML. This makes automatic formatting work when the source HTML is captured from the browser and placed in an editor.

Improve comments associated with ISRs, sleeping and locking.

Add code to support onewire clock chips DS2417 and DS2415. Add detection and reporting of a number of other onewire sensors without support for those sensors. Set time from these chips at boot and store time in them as time is set by other means. One of the chips is selected to use for this purpose. The same chip will always be selected in a static hardware configuration. This code is untested.
Rename some routines and variables in anticipation of adding onewire sensors other than temperature.

20191114 Not logged in

Provide menu items for more sensor types.

Move all javascript to the head portion of the web page.

Improve timeservices debug reporting.

Fix bug reporting time since boot when time is not yet set.

GPM and LPM implementation completed.

Change the ESP command to be a CPU command.

Isolate time checks from loggerYield.

Testing and status code added to espserver.cpp.

Proper recovery of pin types at boot.

Convert time checks for delay to use constant string arguments.

Improve some time checks. Remove a few unnecessary checks. Isolate what the checks apply to so reporting will be better.

Resolve issues passing F() arguments to subroutines that were quietly converting arguments of ROM strings to String type.

20191104 Not logged in

Correct errors in production of web pages that resulted in non-matching blocks. This causes some devices to look like they had lost data.

20191030 Not logged in

Add loggerYield calls in web services support code to ensure data is logged while waiting for web services.

20191028 Not logged in

Also built as 1(47)-127.

When a line from a WiFi client and the line is not terminated with a LF wait a little while (10ms) to see if more characters show up. This resolves issues where clicking on a button seemed to lose the arguments that were used to display the current page.

Find and partially repair issues in client handling that resulted in poor performance when the LOGGER satisfied a request for a web page. The original code was stuck in handleClient() until the web client terminiated (or a related timeout occured). This failure improved by limiting the retry activity to 550 ms. The handleClient() routine was called frequently (this is now required). The new timeout limits how long waiting can be.

Handle parameters to a web page that use only LF to end a line. CR LF pairs are still what is normally expected. A lone CR is never expected. This prevented long hangs when the lone LF occured.

Initialize pins to be inputs by default. Improve pin status initialization related to recovering pin status at startup. Do not recover pin status for pins that control edge detection hardware.

Rework menu to improve clarity, seperate items derived from pulses from actual sensors. Expose Temperature, Humidity and voltage directly.

Improve delay checking. Adjust some allowed delay times to larger numbers.

Improve some comment formatting to support DOXYGEN.

Improve reporting of NTP time updated when no time difference is noticed.

Make I/O expander pin configurations and desired outputs part of the data saved across reboots.

20191023 Not logged in

Add table to get liters per minute from pulses. Gallons per minute are computed internally from liters per minute units.

Add humidity page. Rework menu to identify sensors and pin types.

Change default home page.

Add Voltages to the menu. Make selection of sensor types more generic.

In handleClient go back to looping until the client is available or disconnects.

20191021 Not logged in

Some changes prior to 20191009 are reported here.

Report timing and status in espserver.cpp. This helps find a bug in web page header parsing where lines formed without CR LF pairs wait for a timeout. The timeout is reduced but the bug is not really repaired.

Update comment format for improved DOXYGEN parsing.

Change the network up test timing so it uses 13 minutes instead of 10. This helps determing what the cause of a reboot is.

Add the ICACHE_RAM_ATTR attribute to ISR routines so the latest version of the locator will place them properly.

Add flow services for LPM based on a counter. The ratios are hard coded and need to be updated. A parallel set of pages for GPM should also be implemented using the same set of ratios and a known ratio between liters and gallons.

When running as an access point do not go to the WAN for time.

Improve messages printed when an NTP time update shows no delta.

Update copyright and version notices.

Add direct menu support for presenting temperature pages.

Add additional reporting of long delays with timeservicesCheckForDelay calls.

Remove license grants to Airborne Sensors.

20191009 Not logged in

Convert to Arduino 1.8.10 and update libraries to the latest versions.

Rework as needed for Windows 10 and winzip 24. Repair some zip operations to include more things in the release.

20171224 Not logged in

Allow "" for the value of a parameter to clear the value in the PARAMETER_SET command.

Add a page to report average RPM in an interval based on the pulse count inputs.

Do a better job of limiting to pulse counting pins. Used for new RPM page and on the Kilowatt hours page.

Repair some off by 1 issues in the number of columns in a graph and lines in a table of values. Also update the start and end times of the graph so the first and last bars are not partially obscured.

Initialze the map of pulse counting pins to sensorID. This fixes a latent bug if the map was ever used with some cells uninitialized. This also allows the RPM and Kwh pages to skip pins that are not pulse counting pins. The old code worked because the pulse counting pins were always in a group at the beginning of the list of pins.

Add a test to see if a sensor ID is a pulse counting pin.

Fix error reports for non-existant parameter name to include an EOL.

20171030 Not logged in

Report cause of reboots.

Report count of reboots.

Detect software reboots and report that as the cause of a reboot. A software reload followed by a reset button push will report a cause of UNKNOWN.

Add SLEEP command support for making the network sleep. This is only for power consumption testing during a controlled sleep.

20171008 Not logged in

Repaired reboot reason so it is reset after each boot. It should now say the reboot reason is unknown if a crash occured. Add a count of the number of reboots.

Report the array of bits that marks if a variable should be uploaded to the M2X cloud as a numeric value instead of a string.

Turn on reporting of database start and end times and indexes.

20170913 Not logged in

Added GPS fix parsing commands. They only look at the time and are largely untested. If a $GPZDA message is recieved on the serial port the time is set. Time services are updated to log that the time setting came from a GPS message.

Added the concept of a read transaction to flash processing. This eliminates the need to open and close the file for each sample that is read and dramatically improves the speed of displaying a large number of points.

20170903 Not logged in

Added Sleep command for testing low power processor sleep modes. The implementation is incomplete.

Report the last reboot cause in a number of places.

Fix format of MAC address reporting.

Fix reporting of numeric permament variables.

Provide a link to the security setting page in the main menu.

20170615 Not logged in

Rename all public i2cservices routines to start with the full prefix 'i2cservices'.

Update some ??? comments to improve the discussions. Make some into @@@ comments.

Proper humidity reporting from the MS8607 pressure/temperature/humidity device. More complete temperature compensation as well.

Add 10 minutes as an allowed interval for the time between samples. Add a quarter of the year as an allowed time period in the choices of web presentations.

20170522 Not logged in

DNS now works. The Time server is first tried via DNS lookup. If that fails there is a static IP coded that may work.

Fix a bug in the detection of the AC module. The module will now only operate if the jumper above left of R82 is shorted. the 1(32) version would never detect an AC module.

The calculation of the MS8607 pressure and temperature now do the second order adjustment specified in the data sheet. This is a complex change to the calculation with two inflection points one at 20C and the other at -15C.

Add more debugging printouts to the onewire code.

Add Atmospheric Pressure datatype and use it to report MS8607 pressure in millibars.

Add automatic detection of I/O module type. Report if an unexpected type is at any address. Allowing 4 I/O modules of arbitrary type is possible but the database would then need to handle configurations differently or pre-allocate all possible types.

Rename the DVLR table of I2C addresses.

20170515 Not logged in

Update MS8607 code to properly read an convert pressure and temperature values. Humidity still has no response, does not seem to be a hardware issue, several modules fail in the same way. Lots of issues and inefficient time to read remain to be resolved.

Report the hardware serial number in web pages and version printouts.

Update parameter reporting to have number, string and HEX types. This makes reports of Onewire devices better. There is no support for the HEX type to be a settable parameter.

Fix some outputting formating.

20170327 Not logged in

Emit uints as part of sensor information on sensors page.

Add controls to emit hours, minutes and seconds fields as part of an ammount of time output. Emit the hours and seconds in a few places where that makes the interface more understandable.

Add a new control to set number of columns as an amount of time which computes the count based on the current time span.

Improve handling of the sensors that need to call a pre-read function a while before taking a sample. Make sure that a failure in wait for completion of the pre-read routines prior to taking a sample does not prevent the system from taking the next sample.

Rework pulse pin handling to do the counting in ISRs. When the I2C system is busy during the ISR then postpone the count for the main loop. This prevents missed counts due to long operation times in the main loop.

Improve yield reporting for excessive time taken in the main loop routines.

Add control of which sensors are supposed to uplink to M2X. (Cloud logging.)

Improve onewire reporting of errors. Add retries when a CRC error occurs on a read. Add improvements to make sure parasitic reads will work properly. Test parasitic reads (two sensors are OK).

Convert pulse sensing to an ISR so pulses will not get missed when there are long intervals in the main loop. Add ISR read support to the I2C module. Postpone the pulse counting if the interrupt occurs during some other I2C read. Read all pins as a single word to reduce the I2C traffic. Handle cases where the pins are scatterd among many I2C modules.

Rename i2cXXX routines to be i2cservicesXXX.

Add a watchdog test command. Try to ensure that the watchdog is on and will fire if code does not run. There still appear to be system hangs that do not fire the watchdog.

Print the Sensor ID to the console when verbose printing the sensor info.

Eliminate loggerYield with no indication of what code wants to yield.

Make checking for unexpected delays the responsibility of the routines called out of the main loop. The main loop retains one check for 500ms. Any delay that makes a major contribution to that must be checked in the service code.

Report the reason for the last reboot.

20170129 Not logged in

Fix I/O pin control page so a sensible pin of an I/O module that is present is always selected and displayed as the default pin. (Previously tried to display a pin of a missing module.)

Prevent a divide by 0 error in calculating temperature when bad data is returned from a onewire device (all 0s were probably observed).

Fix a bug in calculation of pulses over all time and in calculation of total pulses. Old code got too few counts and the all time calculation stopped at the end of the interval being inspected.

Add support for reporting Watt Hours, similar to reporting pulses but adjusting units and adjusting for the ratio of pulses to milliwatt hours. Add 8 permanent variables to manage the adjustment. As defaults Pulse_0 and Pulse_1 are set up for 15 amp CTs. Pulse_2-5 are set up for 100 amp CTs and Pulse6-7 are set up for 400 amp CTs.

Clean up naming of subroutines that read earliest sample time and newest sample time.

Improve handling and reporting of time between samples. Report times that are too long to read all temperatures.

Repair time triggers to work off the millis() counter rather than the Unix clock. This resolves issues if the clock jumps due to time setting.

Resolve issues where sensor reading might need more time to complete befor a sample is logged.

Improve debugging printout to use the DEBUG_LEVEL symbol pervasively. Better control what is printed in cases where the level is set to 1.

Complete the DLVR pressure sensor services.

Rework use of constant strings to store them in flash. Make more service subroutines accept strings instead of constant pointers because a quoted string is actually stored in RAM. Use the F("") structure to force strings to flash. Use println instead of \n. Review consoleio, security, sensorlibrary, services, tca9539, timeservices, webservices, webpages and xmlservices modules.

Use service routines to test argument presence so F("") can be used as arguments instead of simple quoted strings.

Repair elapsed time comparisons in i2cservices to avoid wraparound bugs. Fix handling in i2cReadFromSlave to not use write operations.

Improve reporting of sensors found and the associated IDs.

Add the concept of reporting a string of HEX digits to permanent paramters, this is used for onwire IDs.
