why only PWM?.. why not use an R2R ladder instead
with precision resistors...
i know they would hog a whole PORT but arent they
easier to implement ??
and they can do DC output values too... a simple
opam in front (voltage follower) will boost current output too...
i am sure most people dont use R2R... but please
tell me why?? i know there must be a reason...
