EDMA Configure-Revisited

Started by mayank agarwal December 15, 2004

Dear All,
i am trying to configure EDMA to transfer data

from
one memory location to another.
I am having doubts
1.How to determine which channel is most suitable

for
configuring,does it depend on synchronization

event,i
want to trigger EDMA transfer on change of some

variable value then if i can trigger interrupt

using
IRQ_enable on external pin4 and then use

channel4,is this procedure right or there is

some other procedure.
2.Which channel is most suitable for chaining

transfer
from one channel to another.
3.Is it better to configure EDMA transfer in

DSP-BIOS
or by writing register values manually
If anone can tell me any example or manual

where
the above issues have been addressed.
Many Thanks in advance,
Regards,
Mayank Agarwal
