#13809 - RE: why hi freq pulse appear in output port |
Hi Ridvvan,
What kind of power supply are you using for your processor? Is it well stabilised? Can it draw enough current? Are the wires from the supply to the processorboard long? Then you can mount some extra smoothing capacitor(s) on your processorboard. Is the processor itself and other IC's on your board decoupled nearby their supply lines? Good luck ! Henk |
