IP5306 - 电源管理

此芯片主要用于电源银行和嵌入式设备作为电源管理设备。它通过 I2C 连接，允许调整充电电流、电压、截止电压。它具有点亮 4 个 LED 以显示电池充电状态的能力。此设备用于 M5Stack。

用法

在使用 I2C 时，始终需要确保使用正确的引脚。在 ESP32 上，如果您不使用默认引脚，则需要注册这些引脚。

Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);

I2cDevice i2c = new(new I2cConnectionSettings(1, Ip5306.SecondaryI2cAddress));
Ip5306 power = new(i2c);

注意 IP5306 的默认地址为 0xEA，M5Stack 使用的地址为 0x75（在此设置为 SecondaryI2cAddress）。

访问属性

所有属性都可以进行调整和修改。以下是如何显示所有属性的示例

Debug.WriteLine($"  AutoPowerOnEnabled: {power.AutoPowerOnEnabled}");
Debug.WriteLine($"  BoostOutputEnabled: {power.BoostOutputEnabled}");
Debug.WriteLine($"  BoostWhenVinUnpluggedEnabled: {power.BoostWhenVinUnpluggedEnabled}");
Debug.WriteLine($"  BostEnabled: {power.BoostEnabled}");
Debug.WriteLine($"  ButtonOffEnabled: {power.ButtonOffEnabled}");
Debug.WriteLine($"  ChargerEnabled: {power.ChargerEnabled}");
Debug.WriteLine($"  ChargingBatteryVoltage: {power.ChargingBatteryVoltage}");
Debug.WriteLine($"  ChargingCurrent: {power.ChargingCurrent}");
Debug.WriteLine($"  ChargingCutOffCurrent: {power.ChargingCutOffCurrent}");
Debug.WriteLine($"  ChargingCuttOffVoltage{power.ChargingCuttOffVoltage}");
Debug.WriteLine($"  ChargingLoopSelection: {power.ChargingLoopSelection}");
Debug.WriteLine($"  ChargingUnderVoltage: {power.ChargingUnderVoltage}");
Debug.WriteLine($"  ConstantChargingVoltage: {power.ConstantChargingVoltage}");
Debug.WriteLine($"  FlashLightBehavior {power.FlashLightBehavior}");
Debug.WriteLine($"  IsBatteryFull: {power.IsBatteryFull}");
Debug.WriteLine($"  IsCharging: {power.IsCharging}");
Debug.WriteLine($"  IsOutputLoadHigh: {power.IsOutputLoadHigh}");
Debug.WriteLine($"  LightDutyShutdownTime: {power.LightDutyShutdownTime}");
Debug.WriteLine($"  LowPowerOffEnabled: {power.LowPowerOffEnabled}");
Debug.WriteLine($"  ShortPressToSwitchBosst: {power.ShortPressToSwitchBosst}");
Debug.WriteLine($"  SwitchOffBoostBehavior: {power.SwitchOffBoostBehavior}");
Debug.WriteLine($"  GetButtonStatus: {power.GetButtonStatus()}");

按钮状态

您可以获取按钮状态

var button = power.GetButtonStatus();
switch (button)
{
    case ButtonPressed.DoubleClicked:
        Debug.WriteLine("double clicked");
        break;
    case ButtonPressed.LongPressed:
        Debug.WriteLine("Long pressed");
        break;
    case ButtonPressed.ShortPressed:
        Debug.WriteLine("Short pressed");
        break;
    case ButtonPressed.NotPressed:
    default:
        break;
}

重要：根据您为按钮设置的的行为，设备可能会关闭与其连接的设备。因此请在设置时要小心。一旦I2C连接断开，您就无法调整行为。

M5Stack配置

M5Stack的配置如下

// Configuration for M5Stack
power.ButtonOffEnabled = true;
power.BoostOutputEnabled = false;
power.AutoPowerOnEnabled = true;
power.ChargerEnabled = true;
power.BoostEnabled = true;
power.LowPowerOffEnabled = true;
power.FlashLightBehavior = ButtonPress.Doubleclick;
power.SwitchOffBoostBehavior = ButtonPress.LongPress;
power.BoostWhenVinUnpluggedEnabled = true;
power.ChargingUnderVoltage = ChargingUnderVoltage.V4_55;
power.ChargingLoopSelection = ChargingLoopSelection.Vin;
power.ChargingCurrent = ElectricCurrent.FromMilliamperes(2250);
power.ConstantChargingVoltage = ConstantChargingVoltage.Vm28;
power.ChargingCuttOffVoltage = ChargingCutOffVoltage.V4_17;
power.LightDutyShutdownTime = LightDutyShutdownTime.S32;
power.ChargingCutOffCurrent = ChargingCutOffCurrent.C500mA;
power.ChargingCuttOffVoltage = ChargingCutOffVoltage.V4_2;
