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. scary man with cigarette
