Use of McBSP as UART

Started by Sandeep Pande April 15, 2003
HI all,

How can we use McBSP as UART ?
I am designing a McBSP to 8051 UART interface. The
interface should work on 2 lines (DX,DR) from McBSP
and (TXD,RXD) of 8051. any related link will be helpful.

regards,

Sandeep

This thread has an idea from me and someone that seems to have implemeneted
something similar. The whole thread hasn;t filtered through to Google yet,
though, so if you have 'proper' news access you could probably find it on
comp.dsp there - the subject was Re:mcbsp

Hi Sandeep,

You are in luck. TI has an appnote on this exact subject - SPRA633a. http://focus.ti.com/docs/apps/catalog/resources/appnoteabstract.jhtml?abstractNa\
me=spra633a

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.
