#include "M5Unified.h"
void setup()

M5.begin();
Serial.begin(115200);
M5.Lcd.setTextDatum(middle_center);
M5.Lcd.setTextFont(&fonts::FreeMonoBold9pt7b);
M5.Lcd.setTextSize(1);
M5.Lcd.setRotation(1);
}
void loop()
{
M5.Lcd.clear();
bool isCharging = M5.Power.isCharging();
int vol_per = M5.Power.getBatteryLevel();
int vol = M5.Power.getBatteryVoltage();
M5.Lcd.setCursor(0, 30);
M5.Lcd.printf("Charging: %s \n\n", isCharging ? "Yes" : "No");
M5.Lcd.setCursor(0, 60);
M5.Lcd.printf("Bat_level: %d%%", vol_per);
M5.Lcd.setCursor(0, 90);
M5.Lcd.printf("Bat_voltage: %d%mV", vol);
delay(2000);
} This program will display whether the battery is charging, the battery percentage, and the battery voltage on the screen, refreshing every 2 seconds.
API
The battery part of StickS3 uses the Power_Class from the M5Unified library. For more related APIs, you can refer to the following documentation:
