I asked the question last week about having an SPI and a UART port on
the MSP430F427 and the answer I received was that there was only 1
hardware function to support either but not both.

What I would like to do in that case is to implement a software UART
port with a hardware SPI port. I found application note SLAA078A that
details how to implement it using assembler but I'm wondering if
anybody has a C implementation. What I want to do is to transmit data
using the TX pin, not necessarily using the RX pin.

Thanks, 

Ken

Look at TI's site for Code Examples, they have both C
and ASM.
