Hi i am new to the C55x world and i have to implement a DTMF decoder
with TMS320C55x DSK for my academic project.i Dont know how to start
and what to do!!! I am not clear about input and output. Can any one
provide a simple solution or code for the DTMF detection in TMS320C55x
dsk. Thanks a lot in advance...
