hybrid programming?

Alright we are a rookie team and don’t have a real programmer helping us. We got this sample code from Timville, for hybrid but it doesn’t work in our program. Can someone please tell us what is wrong with this code, the bold part is the part we don’t know if it is wrong:

  • FILE NAME: user_routines_fast.c <FRC VERSION>
  • DESCRIPTION:
  • This file is where the user can add their custom code within the framework
  • of the routines below.
  • USAGE:
  • You can either modify this file to fit your needs, or remove it from your
  • project and replace it with a modified copy.
  • OPTIONS: Interrupts are disabled and not used by default.

We seriously need help. We have no other help in programming, other than chiefdelphi.com:confused:

Uh, that looks like RobotC syntax… If you’re getting syntax errors or undefined function sort of things, that’s why. You may have to start from scratch, or look for sample code for normal C.

Yep, you’re trying to use ROBOTC code in MPLAB, which just won’t work.
