how to I clear no longer used interrupts in my c programm? right now, they stay active and still use a a lot of resources, even if I never need them again in my programm.
I already took a deep look into the documentation but couldn't find a way to do so.
I hope you can help me out.
What do you mean by "clear" and "resources"?
WiringPiISR clears the current interrupt when it happens, so a 2nd interrupt can be "remembered" the next time round, but that won't consume "resources" (other than a tiny bit of memory)
If your program is sitting with 100% CPU (if that's what you mean by resources), then I'd have a look at your program to see what it's doing - I suspect it's not doing what you think it's doing...
More information? Program listing, etc. ?
