There is a nifty example showing how to make a software UART using the McBSP in TI's device driver development kit. If you go to www.dspvillage.com and navigate to: "TI Home > DSP Village Home > Software > Peripheral Drivers > Driver Development Kit" there is a download link for the source code.

TI has an appnote on this exact subject - SPRA633a. http://focus.ti.com/docs/apps/catalog/resources/appnoteabstract.jhtml?abstractNa\ me=spra633a Regards, -- Matt >regards, > >Sandeep >_____________________________________ >Note: If you do a simple "reply" with your email client, only the author >of this message will receive your answer.
