AD535_readHwi
Function int AD535_readHwi(
AD535_Handle hAD535
);
Arguments hAD535 Handle to codec channel, see AD535_open()
Return Value int Value returned from output of ADC.
Description Allows the user to read the output value of ADC. Unlike the AD535_read
API, it does not use polling to establish that the McBSP is ready for
another sample. Rather, it requires the McBSP to always be ready. In
other words, the AD535_readHwi routine is for use with an Interrupt
Service Routine. The fact that you arrived at an McBSP receive ISR
signifies that the McBSP is ready with another sample.
Example /* The function is included in the ISR associated to
McBSP receive event REVT */
void AD535_readIsr(){
Uint16 val;
val = AD535_readHwi(hAD535);
}
Returns value of specified control register
AD535_readReg
Function Uint32 AD535_readReg(
AD535_Handle hAD535,
AD535_Reg ad535Register
);
Arguments hAD535 Handle to codec channel, see AD535_open()
