RTOS/TM4C129XNCZAD: Is it possible to use two UART connections at same time ?

Part Number: TM4C129XNCZAD

Tool/software: TI-RTOS

Hello,

In my project, I want to use two UART ports at same time.The former is used for LOG mechanism which is used for print error messages or information about important situations and the latter is used for communication like when a specific message arrives to board it executes a specific operation such as printing a banner message.I use UART0 for LOG mechanism and it works perfectly but I can not see UART5 messages when I connect it with a software like TerraTerm. I prefer UART0 and UART5 as they are pinned out at TM4C129XNCZAD. Is that something I missed to enable UART5 at board.c file ? I use TI-RTOS for developing my project.Thanks in advance for your answers.

Best Regards,

Cengizhan YAPICIOĞLU

    Hi Cengizhan,

    Yes, you can have multiple UARTs. You need to add the additional on into the EK_TM4C1294XL.c and EK_TM4C1294XL.h (or whatever the name of your board files are). We only supply the pinmux in those files to satisfy all the examples in the TI-RTOS product. We felt it would make the files to cluttered if we put all the different permutations for peripheral configuration into those files.
