UART code on EM430F6137RF900 (CC430F6137 Target board)

Other Parts Discussed in Thread: MSP-FET

Hello,

I have an issue displaying the output on the terminal when using EM430F6137RF900 with MSP-FET and HMC5883L sensor. When i run just the I2C code with the same setup I could see the output on the console. But when I include the UART code I cannot see the output on the terminal.

When I use the same UART code and using MSP-EXPCC430RFx Experimenter Kit with the same sensor I am able to get the output on the terminal. See the figure below. I hope someone would be able to help me out.

    Hello Fahad,

    The first thing I would check would be your Baud rate for the UART. Please be sure you have set the UART at the correct Baud rate and the terminal is placed at the same value.

    The baud rate and the terminal are at the same rate.
    Thanks

    Fahad,

    I am not sure what your issue is with the informaiton you have provided. please check your USCI register setting to ensure proper baud rate generation. The following calculator can help you with that: 

    Beyond that, I would try an external terminal such as hyperterm or docklight to see if communication is happening. Another debug method would to check the pins with an o-scope or logic analyzer to ensure you are outputting the signals correctly.

    Hope this helps!

    Regards,
