This report discusses the implementation of a universal asynchronous receiver and transmitter (UART) on a TMS320C54xE DSP using the McBSP and DMA and provides a software UART implementation in C-callable assembly code. In order to implement an asynchronous interface such as a UART using a serial device, software must be written to detect and generate the appropriate framing bits. The initialization of the McBSP and DMA and the timing at which each is enabled is critical to the correct operation of the UART. A thorough examination of these issues is given in this report as well as an explanation of the code.……
