Hello
I assume you get a message that TERMIO_PutChar is not available. Am I right?
This is because you do not have any low level functions writing to the test to stdout linked to your application. First you have to determine (decide) which device you want to use as console output (stdout).
In order to be able to use printf in your application you need to link a module containing an implementation of function
TERMIO_Init and TERMIO_PutChar.
TERMIO_Init should include code to initialize the device you want to use for stdout (SCI, ...).
Its prototype is void TERMIO_Init(void);
TERMIO_PutChar should include code to write a character to stdout.
Its prototype is void TERMIO_PutChar(char ch);
I hope this helps.
