[[BR]]This file provides functions for controlling the WARP radio board's DAC chip.

== Functions ==

For all functions the input variable ''baseaddr'' is the base address of the SPI Core.

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L94 void transmitdac(unsigned int* baseaddr, int val)]'''
[[BR]]Transmits a value to a register.  ''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.

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L110 void WarpDac_InitializeSPI(unsigned int* baseaddr)]'''
[[BR]]Initializes the SPI controller for DAC functions.  This function must be called before calling any other DAC functions.  ''dacs'' is the 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.

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L120 void WarpDac_InitializeDAC(unsigned int* baseaddr, unsigned char dacs)]'''
[[BR]]This function must be called at the beginning of the program to make necessary changes in some of the registers.  Initializes the DACs specified in ''dacs'', the 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.

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L144 void WarpDac_Reset(unsigned int* baseaddr, unsigned char dacs)]'''
[[BR]]Resets the DAC registers to their default values.  Calls WarpDac_InitializeDAC, so there is no need to repeat it in the code.  ''dacs'' is the 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.  

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L158 int WarpDac_Sleep(unsigned int* baseaddr, char mode, unsigned char dacs)]'''
[[BR]]Will take the specified DACs either in (mode=1) or out (mode=0) of sleep mode.  ''dacs'' 

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L206 int WarpDac_FineGainAdj(unsigned int* baseaddr, char chan, unsigned char value, unsigned char dacs)]'''
[[BR]]

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L256 int WarpDac_CoarseGainAdj(unsigned int* baseaddr, char chan, unsigned char value, unsigned char dacs)]'''
[[BR]]

'''[source:/PlatformSupport/WARP_Libraries/warpdac_ad9775.c@latest#L306 int WarpDac_OffsetAdj(unsigned int* baseaddr, char chan, short value, unsigned char dacs)]'''
