ImageCraft Products FAQ-O-Matic: I use printf, and nothing comes out.

ICCAVR V6 - and - ICC7 for AVR :
I use printf, and nothing comes out.

You need to initialize the UART. For example,

UART_TRANSMIT_ON();

UBRR = BAUD9600;

Initializes the UART to 9600 baud and turns the transmitter on. These macros are defined in the file avr.h (the baudrate is for a 4MHz clock). It is best to use the Application Builder to generate peripheral initialization code.
