RTOS/TM4C123GH6PM: Using multiple UARTs with TI RTOS

Tool/software: TI-RTOS

Hi forum,

I am a little confused and just wondering at the moment: is it possible to use multiple UARTs with the TI RTOS framework on a comfortable way? On my own hardware I am using the given UART example with a console and a terminal program. Using the SysCallback functionality it works flawless with scanf and system_printf. In a next step I want to use another UART connected to a bluetooth IC. Is there a possiblity to share(?) the SysCallback interface or create another? I could use the interrupt linked to the UART2 device, but this way I have to handle the data myself. In the best case I would have something like scanf(UART0,...) and a system_printf(UART0,...).

Thanks in advance.

Hi Volker,

I don't think I understand your question. When you setup System to use SysCallback, you provide the function to do the putch function, so you are free to do whatever you want in that putch function. We supplied a UARTUtils.c function that gives you UARTUtils_systemPutch, but you can change it however you want.

I misread the documentation regarding the SysCallback function, it was just a misunderstanding :-)
Thanks for clarify this.
