 | | Motor speed question (premature)

Hi, Sorry for my earlier question about the motor speed table. It was a bit premature. After boning up on PWM I found that the values selected represented the "fine" (i.e. less jerky) settings. There can be as many as 16 different steps that can be (...) (29 years ago, 18-Mar-96, to lugnet.robotics.handyboard)

(...) Sure, why not? The way the motor speed table works is that the number is bit shifted out to the motor. Each bit gets the same ammount of time. So if you don't want your motor to move, then you bit shift all zeros. If you want it to run at a (...) (29 years ago, 17-Mar-96, to lugnet.robotics.handyboard)
