Redirecting printf in codewarrior codewarrior V11.0 to a LCD panel?

Hi,

I am using codewarrior coldfire (MCF 82235) V11.0 compiler and I am new to the compiler. I have a project where i want to format the output and print it on LCD display and want to use printf to do this. But when i enable CONSOLE_IO_SUPPORT, it throws UART related errors. Can anybody guide me with step by step instruction to redirect printf to a console other than UART?

Thanks in advance,

Girish

Hi Girish,

The CONSOLE_IO_SUPPORT macro will redirect the printf to the debugger console, this will make use of the IO functions in the console_io_cf.c file. The ENABLE_UART_SUPPORT macro will redirect it to the UART peripheral and makes use of the UART basic driver support in the uart_support.c file. If you want it to print the information to an LCD then you will have to implement the functionality using the corresponding LCD drivers.

Hope it helps!
