Constructor & Destructor Documentation

AD5764::AD5764	(	uint8_t	sync_pin,
		uint8_t	spi_bus_config_pin,
		uint8_t	ldac_pin,
		uint8_t	slot_number = 0,
		double	full_scale = 10.0
	)

Constructor

Parameters

[in]	sync_pin	The sync or chip select of the dac chip. Different than spi_bus_config_pin.
[in]	spi_bus_config_pin	The pin that identifies the bus. More than one dac can share the same pin.
[in]	ldac_pin	The ldac pin used to update the analog outputs.
[in]	slot_number	This number is used to identify the chip or board. (default: 0)
[in]	full_scale	The full scale of the dac voltage in V units. (default: 10)

Member Function Documentation

double AD5764::BytesToVoltage ( spi_utils::Message  message )

virtual

Uses chip specifications (e.g. bit resolution, registers, range) to convert a set of bytes stored in a Message object to voltage. Each DAC has its own convertion function. Check the datasheet of each chip and override the function below accordingly.

Parameters

[in]

message

Message object which stores the bytes for conversion.

Returns

The current voltage setted on the dac register.

Reimplemented from DacSpi.

uint8_t AD5764::Initialize ( void  )

inline

Dummy function for inheritance compatibility.

Returns

0

virtual spi_utils::Message AD5764::InitializeMessage ( void  )

inlinevirtual

Returns

Message object to intialize Dac.

Reimplemented from DacSpi.

spi_utils::Message AD5764::SetVoltageMessage ( uint8_t  channel, double  voltage  )

virtual

Parameters

[in]	channel	Specifies the channel the Message will set the voltage to.
[in]	voltage	Specifies the voltage.

Returns

Message object to write data register.

Reimplemented from DacSpi.
