Hi Umar,

To configure McASP as UART the easiest way to do is through McBSP. Application Note SPRA633 contains information on how to to configure McBSP as UART. Take a look at the C example specified at the end of this document for your reference.

Note: The SPRA633 document can be downloaded from the following link.

Hi Umar,

Take a look at the following link of Starterware with the UART-EDMA example

http://processors.wiki.ti.com/index.php/StarterWare_01.10.01.01_User_Guide#Example_Application_.28EDMA.29

The example can be found at C6748_StarterWare_1_20_03_03\examples\lcdkC6748\uart_edma
