Hi! It seems that your c6211 is not necessarily a slave. If your problem is configuring the McBSP is software. It is easy to control and configure the McBSPs using the DSP/BIOS. Why don't you implement your raised cosine filter using the c6211? The c6211 is quite capable of doing that. --emer On Thu, 22 Mar 2001 wrote: > Hello everybody, > > I'm very new using this c6211.
