MP2722_Arduino

Arduino library for the MP2722 battery charger IC from MPS (Monolithic Power Systems).

Usage

#include <MP2722.h>

void setup() {
  Wire.begin(8, 9); // SDA, SCL
  PowerSystem.init(8, 9);
}

void loop() {
  MP2722::MP2722_ChargeStatus chg;
  if (PowerSystem.getChargeStatus(chg)) {
    Serial.println(chg.description);
  }
  delay(5000);
}
