TM4C123GH6PM: EK-TM4C123GXL ICDI Virtual COM Port

Part Number: TM4C123GH6PM

What baud rates are supported by the ICDI VCP?  Is it a fixed set or is the divider calculated from the requested baud rate value?

  • Hello Chris,

    The Baud Rate for UART COM Port can be adjusted based on the application. Whatever you set for UART0 is what you will get out. That said, for PC communication with a VCP, 115200 sometimes is the upper limit depending on drivers / cable length / adapters etc. That's why we set all our TivaWare examples to 115200 to have the highest performance while being extremely robust across all hardware situations.

  • Hello Ralph,

    I'm looking for some documentation for the ICDI VCP implementation.   Without this I will need to configure the port for each possible value and verify the baudrate with an oscilloscope.  This seems like a huge waste of time.

  • Hello Chris,

    I don't believe we have much documentation for it because the ICDI is just meant for our LaunchPad boards to provide a cheap debug circuit. It is not meant for use in production applications and therefore we do not provide detailed documentation. The VCP feature is to enable quick and simple demonstrations, not to be used as a means to validate baud rates like you are looking for so it is not something we have tested.
