I don't know pic24, but in general two ways to do what you're trying to do
in c.

1) Use fprintf - usage: fprint(file, format, parameters...)
e.g. fprintf(uart4, "%x", variable);
- though I don't know if you can use uart4 directly in that way, or if
there is a way to pointfprintf at uart4.

2) Use sprintf - usage: sprintf(char*, format, parameters...)
e.g. char output[20]; sprintf(output, "%x", variable); for(i=3D0;
i<strlen(output); i++) { putcUART4(output[i]) }
- which should work provided putcUART4 works as I expect.
