printf is fun! It allows a lot of feedback, and i know we'd be stuck without them. Heres a few samples, straight from our code:
Code:
printf("Joystick 1 Y-axis: %d\t Joystick 1 Trigger: %d\r", left_joy, p1_sw_trig);
printf("Relay 1 Forward: %d\t Relay 1 Reverse: %d\r", relay1_fwd, relay1_rev);
printf("Left Wheel: %d \tRight Wheel: %d \r", left_motor, right_motor);
printfs can really help you do anything. just be sure to # include <stdio.h>
