 | | Re: OC2 and OC3 outputs?
|
| Take a look at the schematics, which are linked from the top page of the Handy Board web site. The info you are looking for is in the CPU / memory schematic. For the DC Motor outputs, the board uses a separate output latch---not the timer outputs. (...) (29 years ago, 24-Mar-96, to lugnet.robotics.handyboard)

|
| (...) Thanks for the tip. I got a hold of the book and read some of it. :) I was wondering if sending pulses to the motor would cause "choppy" rotation....or does it occur so fast that inertia effects make it "smooth". Also, with an h-bridge, is it (...) (29 years ago, 25-Mar-96, to lugnet.robotics.handyboard)
