If this is so does it simplify things. This means you can probably use a relatively poor resolution in your PWM. I would _not_ expect to get away with a resolution of just 4 equal-sized intervals however. > What frequency of PWM would be good for DC Motor control The motors are > small motors taking about 100ma at 13.6 Volts DC The lowest you can get away with given the fact that you want to bit bang ten of these. > rgds > ramana > > -- > http://www.piclist.com hint: The list server can filter out subtopics > (like ads or off topics) for you.
