Since standard file IO is not meaningful for an embedded microcontroller, much of the standard stdio.h content is not applicable. Nevertheless, some IO functions are supported. Use “#include ” before using these functions. You will need to initialize the output port. The lowest level of IO routines consists of the single character input (getchar) and output (putchar) routines. Thus, if you want to use a higher level function on a different device, for example printf to an LCD, all you need to do is to redefine the low level function. See Overriding a Library Function. Note: By default, the single character output function putchar sends the character out to the UART device without modification. However, for the output to appear as expected on a Windows terminal program, the ‘\n’ character must be mapped to the character pair carriage return and linefeed (CR/LF). This can be done by using the following statement: extern int _textmode; // this is defined in the library … _textm
