* 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 --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com> Co-authored-by: code8buster <20384924+code8buster@users.noreply.github.com>
