Music player for children using an ESP32

singsang's Issues

Always shows the 1/4 battery icon

Thank you for such a great project, I'm using this project and M5Core2 to make a player for my child. 😊💗

const auto batteryPower = M5.Axp.GetBatPower();

The M5Core2 GetBatPower() implementation of GetBatPower() is to calculate the Watts current Battery.

float AXP192::GetBatPower()
{
    float VoltageLSB = 1.1;
    float CurrentLCS = 0.5;
    uint32_t ReData = Read24bit(0x70);
    return VoltageLSB * CurrentLCS * ReData / 1000.0;
}

float AXP192::GetBatVoltage()
{
    float ADCLSB = 1.1 / 1000.0;
    uint16_t ReData = Read12Bit(0x78);
    return ReData * ADCLSB;
}

Consider using GetBatVoltage()
