Picaxe and Servo problem
Ive been using this picaxe uC for a while and have had no problems, but in my latest project I wanted to pan a servo back and forth. Problem: for the life of me I can only get the servo to move in one direction. It is a GWS pico servo and I have "operated" it on 5v and 6v, so i dont believe it to be a voltage issue. coding issue perhaps? ( I have tried the SERVO command, the SERVO and SERVOPOS command, and even the correct PULSOUT commands to no avail) I have scoured other forums, even rev-ed.com's, but no one seems to have my same problem. As far as I know the SERVO command SHOULD work fine but doesnt. I have tried the commands with and without a 220 ohm resistor on the signal wire, but this seems negligible. When my picaxe 18x is loaded with any servo capable code and the connections are all hooked up, the servo simply moves all the way and stops. the only way i can "reset" my servo to its original position is by quickly removing and tapping the V+ or GND supply wire to the servo. after the servo has moved I can feel the tiny motor jiggle whenever I tap the signal wire as if trying to work. ANY suggestions are welcome!
