Post by thread:[PIC]: PIC with Servo motor

Hi, Is there anybody has a circuits that PIC control the servo motor instead of stepper? Any help will be appreciated. Thanks in advance. cheerrrrrrrrssssss, -=ianc=- Does Ironman still using old microcontroller chip? If so,let's upgrade to a more powerful microcontroller. By then, we program to fly beyond the 1 foot above the ground. _________________________________________________________ Do You Yahoo!?

part 1 1333 bytes content-type:text/plain; (decoded 7bit) Hope this help (by Dale Botkin & B. Knudsen Data) A 1.5ms bitstream (with a 20ms between pulses) will take the servo to the center. 1 to 1.5ms will move the servo in one direction (for example 1.25ms wil move appr. half way to the one direction) and 1.5 to 2 will move it in the other direction... (Note: Above timings vary from servo to servo eg. some servo's center's can be at 1.52ms) Francois {Original Message removed} part 2 13972 bytes content-type:application/x-zip-compressed; (decode) part 3 228 bytes -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:","[SX]:","[AVR]:" =uP ONLY!

You didn't give any particulars, so my generic answer is to control the servo motor from the PIC PWM output and use something like a PID controller in the software to make it do what you want. Of course this also assumes the motor position is fed back to the PIC. ***************************************************************** Olin Lathrop, embedded systems consultant in Devens Massachusetts (978) 772-3129, .....olinKILLspam@spam@cognivis.com, http://www.cognivis.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:","[SX]:","[AVR]:" =uP ONLY!
