CPU triggered EDMA Transfer on c6713 - Alberto Fahrenkrog - 2006-09-04 06:22:00

Hello all!

I'm trying to trigger an asynchronous EDMA transfer by means of a
function, that is, whenever I call this function, it must start the
transfer. I cannot do it over an external interrupt, because I am using
that one for something else. When the transfer is ready, the EDMA has to
send an EDMA interrupt to the CPU
I've been trying to set the event Registers, enable them, enable the
EDMA channel, but nothing seems to work. Is there a straightforward way
to do that asyncronously, that is, function triggered?

Thanks a lot!

Alberto Fahrenkrog C.

Hi, me again!

Just found a solution using the QDMA.

Thanks anyways!
