* Add battery level with lookup table
now uses a lookup table to better calculate battery level of different cells
* LifePo4 and PB battery table - added voltage filter
removed delay from adc reading, added a software filter to smooth out voltage readings. In those applications battery would last hours to days, no sudden change should be expected so a less frequent voltage reading or a more aggressive filtering could be done.
Note: to speed up convergence i initiliazied the last value to the minimum voltage, there are other and better ways to init the filter.
Added LiFePO4 and PB open circuit volta battery tables,
* Fixed ADC_CTRL , Checks for valid ADC readings
line 230/386 For heltec v3 and heltec tracker a different approach was used with the ADC_CTRL pin, now is more uniform using the same code for the 3 boards.
line 236 Check if the raw reading we are getting is Valid or not, count only the valid readings. This could lead to a division by 0 (improbable) so that's why at line 258 there is a check for that.
* updated OCV values
updated value to not OCV but to very low current, almost the same anyway
* Added Alkaline/Nimh voltage curve
Added Alkaline/Nimh voltage curve for AA/AAA and similar cells
* updates variants for new capacity measurement
* trunk reformatting
* trunk fmt
* Add LTO chemistry

* WIP
* Continued wip
* We got em
* Voltage sensor base class
* INA voltage
* Log it
* Stacie's mom has got it going on
* Move declaration up
* Last one
* Sneaky little bugger
* Macro guard to avoid calling methods
Added a counter that counts low battery level detections.
If there are 4 in a row we go to deep sleep.
The battery sense on the RAK4631 seems to be a bit unstable and may
generate 'false' low voltage readings.
My RAK4631 has been running for 7 days now with this fix.
It did 3 days without it.
I still do not have a T-Echo so on that board IT IS NOT TESTED.
(But I hope it will improve things there too)
However, disabled until someone with suitable hardware can test and report
back.
@slavino and @tschundler would you be willing to try it with your boards?
You'll need to uncomment the following line in configuration.h
// #define BATTERY_PIN 35 // A battery voltage measurement pin, voltage divider connected here to measure battery voltage
* Break out debug screen to a separate class and make it thread-safe.
* Break out power state to a separate class.
* Show battery voltage, charging & USB status on debug screen.
* Show GPS lock / no lock
* Fix an off-by-one that I introduced earlier in `drawRows`.
