ADC 7689 Interfacing through SPORT0

Hi ,

 

I modified the code which i got from this forum for Interfacing AD7682 to BF592-A, as per my requirements(AD7689 interfaced to BF526). I have attached the code that i modified. On debugging,  I found that ADC is not getting configured when i run the program. I checked the reference voltage pin on the ADC which had to be 4.096 as per my Configuration Word, but its zero. How do i probe my board to know the SCLK frequency? When i try to display it using VisualDSP++, it shows that its 48MHz as i had set in the code.

 

Why are we doing this?

 

//SPORT Pin Mux config
*pPORTF_MUX = 0;
*pPORTF_FER = 0x00FF;

 

 

I am new to this, the questions i ask might be silly, but i feel that i will get some help from here.

 

Thanks and Regards

Shafi
