I'm using IAR Embedded Workbench Kickstar to program MSP430 F2132.
I want to include in the firmware a function that writes variables in a output terminal, in order to see debug my code.

I tried printf, but was too big for MSP430 and I had an error while building

I'm trying putchar: it builds without errors, but when executing the firmware, I look in the Terminal I/O and nothing appears, the same happens with the putty.

Any information about how to use the putchar it will be appreciated, or a way of showing variables in the terminal.
