The MCP4725 device

Implementations

impl<I: I2c<SevenBitAddress>> MCP4725<I>

pub fn new(i2c: I, address: SevenBitAddress) -> Self

Create a new device from an I2C peripheral and address.

pub fn destroy(self) -> I

Destroy this device and get the I2C instance back.

pub async fn set_voltage( &mut self, dac: u16, write_eeprom: bool, ) -> Result<(), I::Error>

Convenience function to just set the output voltage. Only the lower 12 bits of the DAC value are used. If write_eeprom is true, the DAC value will also be written to the EEPROM and the EEPROM power down mode will be set to Normal.

pub async fn read(&mut self) -> Result<(RegisterStatus, EEPROMStatus), I::Error>

Perform a read command. This will return the value in the DAC register and the EEPROM data.

pub async fn fast_write( &mut self, power_down_mode: PowerDownMode, dac: u16, ) -> Result<(), I::Error>

Perform a fast write. This can set the power down mode and the DAC value. This only changes the DAC register and does not affect the EEPROM. Only the lower 12 bits of the DAC value are used.

pub async fn write( &mut self, power_down_mode: PowerDownMode, dac: u16, write_eeprom: bool, ) -> Result<(), I::Error>

Perform a normal write. This can set the power down mode and the DAC value, and optionally write to the EEPROM. Only the lower 12 bits of the DAC value are used.
