Functions

void transmitdac(unsigned int* baseaddr, int val)
Transmits a value to a register. baseaddr is the base address of the SPI Core, val a 16 bit hex value where the 8 least significant bits are the value to be stored and the 8 most significant bits choose the register in which to store the value.

void WarpDac_InitializeSPI(unsigned int* baseaddr)
Initializes the SPI controller for DAC functions. This function must be called before calling any other DAC functions. baseaddr is the base address of the SPI Core.

void WarpDac_InitializeDAC(unsigned int* baseaddr, unsigned char dacs)

void WarpDac_Reset(unsigned int* baseaddr, unsigned char dacs)

int WarpDac_Sleep(unsigned int* baseaddr, char mode, unsigned char dacs)

int WarpDac_FineGainAdj(unsigned int* baseaddr, char chan, unsigned char value, unsigned char dacs)

int WarpDac_CoarseGainAdj(unsigned int* baseaddr, char chan, unsigned char value, unsigned char dacs)

int WarpDac_OffsetAdj(unsigned int* baseaddr, char chan, short value, unsigned char dacs)
