Re: Timers causing code errors?

My vote would be that you're not clearing the interrupt flag in the ISR.

Re: Timers causing code errors?

Check and make sure "#pragma ... save=" is saving all of the required registers. Which ones are dependent upon your interrupt service routine code and what is used.


Posting the #pragma and the ISR code pertaining to the timer would help.

Re: Timers causing code errors?

We implemented the interrupt-based timer described in the IFI white paper.

It has worked fine for us without errors.

Re: Timers causing code errors?

ok, ill post it next time i get my hands on the code (tomorrow probably)

and i think i am clearing the flag... the error only occurs when we do a hard reset of the robot, and a soft reset fixes it.
