i need to generate a pwm signal with variable duty cycle, with a period of about 1s. as far as i understand, with the 16f872 it is possible to get a period of up to 65ms, when running the pic at 4mhz. what is the best way to get a slower period? thanx tino -- http://www.piclist.com hint: The PICList is archived three different ways.
