Writing a 1 to the corresponding event (If your destination is McBSP1 then write to Event 14) will trigger an EDMA event. For more info refer to SPRU234 EDMA controller reference guide, page no. 1-6 > 2) IS using the command EDMA_setChannel is enough to trigger an EDMA > transfer? Yes. I think this event essentially writes to Event set register so it should do the trick. > I want to trigger an EDMA transfer when a certain flag is set. > the source is a buffer in memory and the destination is the McBsp. > could some please explain me the procedure or send me a refference > code? > FIrst step would be to configure the EDMA channel as you want, set source and destination address , set the options registers and all other parameters in PARAM table. Then as soon as you detect that flag is set, call EDMA_setChannel routine and pass the required channel handle. Hope this shud work. -Tarang P.S. For details abt how to set-up EDMA parameters and stuff , I am refering to MCBSP- UART document. spra633b. Go thru the code to know how to setup the EDMA channel. > please answer this, > thanks, Offir. > > _____________________________________ > Note: If you do a simple "reply" with your email client, only the author of this message will receive your answer.
