Unstable battery voltage measurements #38

Open Maaciej opened 1 year ago

Maaciej commented 1 year ago

First readings of battery voltage were very unstable for me, not good for automating battery monitoring:

First battery cycle, multiple radical dropdowns

next cycle

TL;DR moving voltage reading to the beginning of "setup" did some improvement. (I have 15 minutes deepsleep timer, to see in more interacive way what is going on)

3 last cycles

All my changes are visible in commit 1629c91d2a13971aee2231d73eb6c70a7a6b3133 of
https://github.com/Maaciej/TTGO-T-HIGrow.git in branch "doodling".
