MCP4725 represents a MCP4725 DAC.

func New

func New(bus embd.I2CBus, addr byte) *MCP4725

New creates a new MCP4725 sensor.

func (*MCP4725) Close

func (d *MCP4725) Close() error

Close puts the DAC into power down mode.

func (*MCP4725) SetPersistedVoltage

func (d *MCP4725) SetPersistedVoltage(voltage int) error

SetPersistedVoltage sets the voltage and programs the EEPROM so that the voltage is restored on reboot.

func (*MCP4725) SetVoltage

func (d *MCP4725) SetVoltage(voltage int) error

SetVoltage sets the output voltage.
