Compiler: Multiple UART with printf

Sahil

Tool/software: TI C/C++ Compiler

Hello Everyone,

I need to use three UART ports with my microcontroller. I want to use printf, fprintf etc with all the three ports. How can I direct stdout, stdin to work with all three ports ?

i guess i will need fopen statement if so please provide some example that opens multiple ports same time.

I thank you in advance for your help.

What processor? For the MSP43X's you can only printf() to JTAG.

I lack the expertise to help with the lowest level of code that outputs a char or string to a UART. But once that is done, you can interface the printf and related functions to it using the section titled The C I/O Functions in the ARM compiler manual. Pay particular attention to the section titled Adding a User-Defined Device Driver for C I/O.

Thanks and regards,
