Hi I am using CAN communication between C2810 DSP and ARM. At high data rate such as 500 kps I am getting errornous packets. I want to know how to decide sampling point, is changing dtaa transfer speed requires change in sampling point. Thank and Regards, Ruturaj Devkar. _____________________________________

Ng- This is a good news group question. Are you saying that the PCM3003 daughtercard is not providing 16 kHz, but actually something else? Clearly if your sampling frequency is off then measured delay will not match your MATLAB results. O ya. Di

Hello everyone, I am trying to get 1024 samples per frame from my SIO_reclaim(). The aic23 is set to 48KHz sampling rate. So shouldn't there should be a full buffer every 21.3 msec? But when I try to find the time using CLK_gethtime(), I get a buffer every 24 msec. Tried it with 32 KHz sampling too. Again instead of getting a full buffer every 32 msec, I get it every 24 msec.
