DAC63004/DAC63004W - Ultra-low-power quad-channel 12-bit smart DAC with I²C, SPI and PWM

This library supports DAC63004 and DAC63004W devices. Currently the implementation allows I2C connection to the device. SPI will be added in the future.

Usage

Warning: If using an ESP32, make sure to properly setup the I2C pins before creating the I2cDevice. Add a reference to nanoFramework.Hardware.ESP32 NuGet package and add the following code lines:

//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the I2C GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);

For other devices like STM32, please make sure you're using the preset pins for the I2C/SPI bus you want to use.

Hardware Required

DAC63004W EVM
Male/Female Jumper Wires

Circuit

SCL - SCL
SDA - SDA
VCC - 5V
GND - GND

Code

The following code creates an I2C configuration and instantiates a Dac63004 object. Then it prints the Minimum System Voltage detected by the device at boot. Last it enters a loop where it prints the current Vbus voltage each second.

I2cConnectionSettings settings = new I2cConnectionSettings(1, Bq25798.DefaultI2cAddress);
I2cDevice device = I2cDevice.Create(settings);

using (Bq25798 charger = new Bq25798(device))
{
    Debug.WriteLine("");
    Debug.WriteLine($"DAC63004 connected to I2C{device.ConnectionSettings.BusId}");
    Debug.WriteLine("");

    Debug.WriteLine($"Minimum System Voltage is config @ {charger.MinimalSystemVoltage.VoltsDc:N3}V");

    while (true)
    {
        Debug.WriteLine($"Current Vbus: {charger.Vbus.VoltsDc:N3}V");

        Debug.WriteLine("");

        Thread.Sleep(1000);
    }
}
