INJ signal signal with only one int
It would be useful for my Mpguino version if I could get one external interrupt free. So I thought about how INJ time could be measured with only int0. My idea: trigger the interrupt on every signal change and meter time between int calls. Then compare actual measurement with last one. Shorter one should be INJ time? What is your experience with this signal, is injection time realy always shorter then time between them? I think it should be true but i am not shure.
