[En-Nut-Discussion] RE: PWM

[Raul Valle]

Curtis thanks for  the reply:

The thing is the channels available are not enough, there are more servos to control......they are going to be controlled by a command sent to them from the computer .... any idea in how to achieve to control all the servos not affecting program please let me know... I appriciate the help./

Is there a particular reason you're avoiding using the hardware PWM?  They'd be 
much simpler, more accurate, and would take no CPU time once set up.

Of course, if they're all already in use, or you have to use a pin they can't 
control, I'll understand.
