Please help, timer issue

[zako234]

Hey guys, I'm a fisrt time coder for this year, and I need some help with my code. I have a timer which I can get working in normal mode, where the joysticks control the robot, but I cannot get it to read in autonomous mode. Here is the code from my user_routines_fast file. Thank you very much in advance!

The simple answer is that Process_Data_From_Local_IO() isn't ever being called from your User_Autonomous_Code() loop, so your timer isn't ticking.

The more complex answer is that most people setup their timers to operate as interrupts in InterruptHandlerLow (), so they happen regardless of what loop you might be caught in, a la, http://www.ifirobotics.com/docs/time...004-jan-14.pdf
