Function Documentation

LTCDAC_InitCS()

LTC1451_t LTCDAC_InitCS	(	SPI_TypeDef *	SPIx,
		GPIO_TypeDef *	GPIOx,
		uint16_t	GPIO_PIN )

Initiliazes SPIx and the external LTC1451 DAC. Also sets up the sofware CS pin for SPIx.

Parameters

SPIx	SPI Peripheral (Ex. SPI1 or SPI2)
GPIOx	GPIO Port for the chip select pin (Ex. GPIOA, GPIOB, ...)
GPIO_PIN	Desired chip select pin on port GPIOx (Ex. GPIO_PIN_0, GPIO_PIN_1, ...)

Returns

Struct containing all necessary data for the DAC

LTCDAC_SetOutputCS()

void LTCDAC_SetOutputCS	(	LTC1451_t	LTC_DAC,
		uint16_t	outputVal )

Sets the DAC's ouptut voltage (0-4.095v)

Parameters

LTC_DAC	Struct containing configuration data for the DAC
outputVal	Voltage to set on the output pin of the DAC
