AD535 API Module
Writes value to input of DAC
AD535_writeHwi
Function void AD535_writeHwi(
AD535_Handle hAD535,
int val
);
Arguments hAD535 Handle to codec channel, see AD535_open()
val Value to be written to DAC.
Return Value none
Description Writes value to the input of the DAC. Unlike the AD535_write API, it
does not use polling to establish that the McBSP is ready to write another
sample. Rather, it requires the McBSP to already be ready. In other words,
the AD535_writeHwi is for use within an Interrupt Service Routine. The
face that you arrived at an McBSP transmit ISR signifies that the McBSP
is ready with another sample.
Example /* The function is included in the ISR associated to
McBSP receive event XEVT */
void AD535_writeIsr(){
Uint val = 0x0066;
AD535_writeHwi(hAD535,val);
}
Writes value to specified control register
AD535_writeReg
Function void AD535_writeReg(
AD535_Handle hAD535,
AD535_Reg ad535Register,

);
