Yes, I would expect it. I don't know what the maximum is for interrupts, but one every 0.2 microseconds seems rather extreme.
What are you trying to do and can it be accomplished in a friendlier fashion? Cheers, Lloyd > Hi > > We are triggering an interrupt on GPIO0, successfully and the ISR is > being run.
