Mesure Volts on pin 35 TTGO 1.6.1 #59

Closed bobo3k closed 1 year ago

bobo3k commented 2 years ago

Hi, I have tried everything (dac, analogRead...) and I never get accurate values out of PIN 35, which should work on a Lilygo T3 V1.6.1 Would you be kind enough to provide a code that allows to get the voltage of the battery (https://www.amazon.es/gp/product/B01KKJP8L6/)? Many thanks in advance, Baudouin

Hi, Trie to use the PMU class: AXP20X_Class PMU; this library has this function, PMU.getBattVoltage(); but before use you need to init the chip, pmuInit();

Thanks a lot!

I was actually using Pangodream_18650_CL, but it stopped working somehow... I then spotted that the board was faulty, got a replacement, and this same library worked perfectly!

Thaks again!
