In a message dated 12/1/04 9:36:32 A.M. Eastern Standard Time, writes: Recently i am using MicroCore11(68HC11) instead of remote control to generate PWM(pulse wide modulation) to Scorpion(a motor controller from robot-power) to control the motors. However i am unable to generate the correct pulse (but instead i have square waves),and the motor can't move. When i use function generator to generate pulse to the Scorpion, the motor can move. ================================================ Is the scorpion using radio control servos? These require a 1.5ms pulse every 10 ms. There are many examples of how to program rc pulse trains.... look at the web sites in the technological arts web ring... I have a microcore11 and I program it using imagecraft c. I can help you with your program if you send more info in an email. [Non-text portions of this message have been removed]
