(from src/extra_variants/README.md)
This directory tree is designed to solve two problems.
- The ESP32 arduino/platformio project doesn't support the nice "if initVariant() is found, call that after init" behavior of the nrf52 builds (they use initVariant() internally).
- Over the years a lot of 'board specific' init code has been added to init() in main.cpp. It would be great to have a general/clean mechanism to allow developers to specify board specific/unique code in a clean fashion without mucking in main.
So we are borrowing the initVariant() ideas here (by using weak gcc references). You can now define lateInitVariant() if your board needs it.
If you'd like a board specific variant to be run, add the variant.cpp file to an appropriately named
subdirectory and check for \_VARIANT_boardname in the cpp file (so that your code is only built for your board).
You'll need to define \_VARIANT_boardname in your corresponding variant.h file.
See existing boards for examples.
This approach has no added runtime cost.
No need for _V05 and _V03 definitions - I think there was a slight misunderstanding
on how variant files are supposed to _decrease_ #ifdef code in the cpp files.
* Currently only on heltec tracker, but could use ADC_USE_PULLUP on other boards that could benefit
* Thanks @todd-herbert and @StevenCellist for the instructions ;-)
* Remove nasty Heltec_wireless #ifdefs that got somehow added to Power.cpp, instead use proper variant defs
* Cleanup adc enable/disable code a bit for less copy-paste cruft
* Cleanup GPS, add UC6580 autodetect
Our GPS code autodetects devices by default. Previously UC6580 was
statically assigned, and had its own baudrate configuration inside
the GPS code.
This change adds autodetect functionality for the UC6580 and moves
any 'special' GPS baud rate requirements for a variant out into the
variant configuration. Thereby cleaning up core GPS code a little,
saving the whales, and curing global warming.
New Functionality:
* If GPS_BAUDRATE is defined in variant.h, GPS autodetection will
try that baudrate first.
* UC6580 GPS chips are now automatically detected
* Only run speedSelect skip the first time

It's no longer needed.
Schematic shows the following:
Pin 3 is Vext on v1.1 - HIGH enables LDO for Vext rail which goes to:
GPS UC6580: GPS V_DET(8), VDD_IO(7), DCDC_IN(21), pulls up RESETN(17), D_SEL(33) and BOOT_MODE(34) through 10kR
GPS LNA SW7125DE: VCC(4), pulls up SHDN(5) through 10kR
OLED: VDD, LEDA (through diode)

* Fix Heltec Tracker Screen issues
Fix Heltec Tracker Screen issues like wrong offsets, display size and screen not shutting down.
Divides board into two different envs for 1.0 and 1.1 version PCB
* Helteck wireless tracker default version V1_1
* rename heltec tracker 1.1 - trunk fmt
rename varian of heltec tracker 1.1 to "heltec tracker" to be retro-compatible.
Trunk formatting.
* Heltec Tracker increase Screen update to 3Hz
Heltec Tracker increase Screen update to 3Hz from 1Hz
* 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
