CCS/MSP-EXP430FR2355: UART not connecting with OOB demo

Part Number: MSP-EXP430FR2355

Tool/software: Code Composer Studio

I just unpacked this MCU and am trying the out-of-box demo to check functionality. The loaded program works (the lightsensor part of the code starts up and works while the GUI tries to connect). The connections are shown below (COM5 is my FET connection). I try connecting to COM4 when I run the OOB GUI and the program gets stuck in "waiting for data...". I gave it up to two minutes without any success. Any ideas of what to do to fix this?

  • Hi David,

    I have 2 things I'd like you to check for me that will hopefully fix this:

    1. The GUI requires a BAUD rate of 115200. Can you check the baud rate of the LaunchPad by going to device manager (like you do in your screenshot), right click on MSP Application UART1 > Properties > Port Settings. If the baud rate is not 115200 please change it in the "Bits per second" field

    2. The LaunchPad runs either the Light sensing demo or the GUI demo (not both at the same time). You can switch between the 2 demos by pressing the S2 switch on the LaunchPad. Try pressing this to activate the GUI demo.

    Thanks,

    Mitch

  • Thank you. The baud rate was showing 115200 on the GUI but not on the device manager. It fixed itself once I forced it to 11520 in the manager.
