[DPRG] PWM Frequency and torque

Hmm.. now I think this is an interesting issue that
lot of people are getting interested in.

My biggest problem is I see so many PWM based
questions surfacing here and there sporadically.. and
almost noone seems to agree with each other and many
don' understand what's going on...

Why is PWM so hard to understand and apply in

But I am seriously starting to get worried..

I am feeling a negative energy around me.. :)

It seems like people are really not "in tune" (pun
unintended) with me using 250Hz to drive my motors..

At any higher freq there is a HUGE drop is torque..

But I will get my scope and see what's going on..

Wow.. is it possible that you have a sample ?

Is the 50 lines ASM or HLL code ?
