AD535_writeReg

AD535_writeHwi

Writes value to input of DAC

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
