The code you provided we were able to compile without problem. Since
we have an MSP430BT5190 from the eZ430-RF2500 development kit, we
think that the UART may need some further configuration. The website
for our kit shows the uart TX and RX lines on port 10.4 (tx) and port
10.5 (rx).
To begin with we put in some code to alternatively blink the test
LEDs. The program which we wrote is attached (uart-blink folder) and
when loaded to our kit does blink the LEDs. However the character we
send out doesn't appear.
Looking at your sample code, we suspect the problem may be in clock
configuration. For a 9600 baud clock I suppose we need to divide the
main clock which is at 25 MHz. However, at present I am working to
better understand the UART configuration code.
If you have any suggestions for corrections or further reading on the
subject, help would be greatly appreciated.
Thanks.
Best,
Priyasheel
