Delay problems

[rnielsen]

Has anybody had problems with the delay_ms() statement hanging your program? I had a program working just fine and after adding a bit of code things hang when it hits the first delay statement. I didn't touch the #fuses or #use statments and I added code in various parts of the body and now POOF it pukes on me. I'm not sure if I want to scratch my head and try to remember where I changed things either. Just wondered if anybody has had a problem with them hanging a program.

Nope, never had delay_ms() cause problems, even with the supposed bugs in some of the recent versions.

Do you use delay_ms() both in an ISR and in your non-isr code? The compiler makes delay_ms() reentrant if you are using it in both. Part of reentrancy I think involves turning off interrupts. Perhaps you're missing an interrupt. But then again, that interrupt flag would pend, so who knows.

A-HA! I was able to figure out what I had done. During my edits, I had remarked out timer_2's ISR but left the interrupt enabled. The program would run just fine until I called my first delay_ms() and then it would hang. I tested this with the other timer interrupts and they caused the same thing. Oh well. *shrug*
