Yes, but my understanding is that the "internal" interrupt latency and/or software overhead is much higher than it is for the "external" interrupts – so I was hoping to find a way to use a single external interrupt. I have't actually measure the difference yet, so I don't know how big a … WebIn your application, a reasonable design would be to have an interrupt every ms, which increments and checks a counter value. I'm sure you can work out some suitable logic to set and test the counter to get 200 ms between turn on and turn off events. In the worst case, an ISR can run until the next interrupt of the same type occurs again. progressive weakening and size reduction
