Hi to all engineers, I need to drive 4 outputs the sequence I do not yet but I know the speed is 60 hz continuously none stop unless there is some thing wrong with it and at the same time I have to do AD conversion and some other basic functions bit test and bla bla. I am thinking to use timer1 with second crystal just to do the 60hz pulsing but then I am king of afraid of adding glitches or other unknown problems in 60hz loop or maybe easier way to do it by using 2 pics or so. my question is which method should I use? can single pic can do this how should I setup? any help will highly appreciated.
