Battery status?
-
Hi, is there any way to know the battery percentage of the M5Stick-C? I want to know when its "fully" charged and what is the real-time percentage of the battery!
Thanks

I've just started out but it looks like the following shows the voltage and mine maxed out at 4.178V, this gradually decreases and I think below 3.6V isn't really usable. You can use this and some testing to determine the percentage of battery.
#include "M5StickCPlus.h" TFT_eSprite Disbuff = TFT_eSprite(&M5.Lcd); void setup() { M5.begin(); M5.Axp.ScreenBreath(8); M5.Lcd.setRotation(1); Disbuff.createSprite(240, 135); Disbuff.setTextColor(TFT_WHITE); } void loop() { Disbuff.fillRect(0, 0, 240, 135, TFT_BLACK); Disbuff.setCursor(10, 10); Disbuff.printf("BAT_V: %.3fV",M5.Axp.GetBatVoltage()); Disbuff.pushSprite(0,0); }
There are other options power functions that may help in this doc:
