I am using a Picaxe 18X mounted on an SD21 Servo Control board to read signals from a Futaba radio receiver using Pulsin, process the values and send the outputs to the connected servos.
Everything apears to be working OK except that the SD21 board seems to be sending interference to the servos which are still connected directly to the receiver, making them jitter. The problem only starts to happen when I have some servos connected directly to the receiver and some servos via the SD21. As soon as I remove the servos which are connected to the SD21 (but keep the SD21 connected to the receiver so that it still processes the inputs) the jitter on the servos which are connected directly to the receiver disappears.
I have checked cable connections, I am using one battery to power the receiver and one battery to power the SD21 with both negative leads connected together.
Does anybody have any suggestions?
