Arduino Quick Start

StickC-Plus SE Battery

APIs and example program for reading the StickC-Plus SE battery status.

Example

M5Stack board manager version >= 3.3.8
Board option = M5StickCPlus
M5Unified library version >= 0.2.18
M5GFX library version >= 0.2.24

cpp 
#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 displays the charging status, battery level, and battery voltage on the screen, refreshing every 2 seconds.
