I am trying to make an interface between the PC and a pic using the max232a chip
I wonder about my code.
i know what should the command for such a thing be but i would like some help for the printf that i should use(positioning if it should be outside or inside my main loop) and (an example of the printf if it is to print 2 float numbers values)

printf() is typically re-entrant for any compiler so it should not appear in interrupt service routines. It is OK for use in main() or a subroutine.

Code:

printf("Hello world, the numbers are %f and %e\r\n", fnum1, fnum2);


The first number, fnum1 will print as a "standard" floating point while fnum2 will print using exponential format. You can modify the %f or %e to change the number of decimal points and field width. Refer to a C language reference such as K & R's book.

The CCS help file gives some simple examples, especially if you need to see how to use streams.
