Pb with edma & Mcpsp1

Started by nadbret ●August 6, 2003
hello,

I use the DSK C6711 board with the PCM3003 daughtercard.
I want to use the EDMA to transfer my data at 48 Khz. I use an Edma
channel to receive the data from the serial port Mcbsp1 an an other
to transmit the data to Mcbsp1. But I have an awful output signal. I
think that my configurations for the EDMA are not correct but I don't
know where..
Do someone already use the Edma with the serial port Mcbsp1?
I send my programm, if someone can help me..

thanks #include <csl.h>

Dear ,
Could you add the McBSP head file created by CDB? Check if the EDMA
source/desnestion is correct for Xmt/Rcv? ----- Original Message -----
