Interrupt from comparator - S/W guidelines.

Anonymous · ‎Mar 08, 2013

Hello!

How to generate an interrupt from comparator's output without using any DigBuf module? Can I get two interrupts using the same transition before & after routing to a DigBuf ? I read related stuff on cypress documentation but wasn't able to figure out anything conclusive.

I did include pragma interrupt_handler in the beginning. I tried incorporating ljmp _Comp1 (taking Comp1 as the name) in boot.tpl file & then to begin with, in my ISR, which I'm coding in C, I tried to change an LED's status everytime an interrupt occurs but couldn't succeed. Tell me the correct sequence and/or example code for the same.

Thanks a lot.

I tested --- it works fine.

There is a file generated named COMP_INT.asm where the modifications have to be made

Attached is a working project. External connection is needed from Port0_0 to Port0_1, interrupt occurs once a second.
