HI! Excuse me for all this mess I did not know how to insert the subject = [pic] in the subject line, hope this is correct. I am relative new in this pic stuff but would be happy to receive some = samples using PWM on a=20 16C712. I am going to make a servoamp chip with PID filters using 3 pots = that can be read by 3 pot or ad input. I'll also use two inputs for the quaderature = encoder that=20 sendts 2 set of pulses 90 deg phase-shifted which tells which direction = it runs. I'll also have two inputs from a LPT-port on a pc that sends step and = directions to the 16C712. The error is calculated between the encoder up/down counter = and the input from the pc. If anybody could help me I would appreciate verry = much. I would=20 also be happy if anybody could help me programming this chip, at least = in the start. If it is possible to get samples in pic-basic pro it would be nice. Other pic-chips could also be of interest . Best regards Ernst Aardal -- http://www.piclist.com#nomail Going offline?
