Hi,

You might want to find out why the big PIC doesnt want to work properly. Do you have a nice and clean supply voltage (or do you get spikes when you start and stop the DC motors)?

Do you have enough power at all?

Do you have capacitors close the the power pins of the pic?

Do you have brown out enabled?

PCB or a ball of soldered wires?

X-tal, RC or external oscillator?

I would reccomend you to try to solve this issue and then you would get a much easier project. There must be a reason for this so I think we keep the 2 pic design as Plan Z.


What do you mean with "it doen't work well"?
