Hi, I encounter a problem with the changing the sampling rate of the onboard codec in C5402 DSK board. I try to set the sampling frequency at 16Khz... but when I test it and found out that it cut off at 4Khz instead of 8Khz.... I try to change to other sampling rate, but it still seems to be cutoff at 4kHz. Can anyone advise? Regards, Jun Hong |

Jun Hong- How do you set the sampling rate? Using your own code, or CCS library? We found in 2001 that using CCS to initialize the AD50 and setting some of its register values, including sampling rate, was not always consistent, so we used some asm. code to do it. It's in the C54x archive: http://groups.yahoo.com/group/c54x/message/436 You might try that and see if you can get it to work.
