Can someone help me out with the scematic of the motor controller with PIC18f4331, l298 and a quadrature encoder. I already implemented the motor controller with a pic 16f877a, but later I had to abandon that idea as 16f doesnt support quadrature encoder modules.. I adjusted the 16f circuit diagram for 18f4331 , but It doesn work.. Can someone help me out in figuring what the problem is in this circuit diagram?

Hi there.
I m also getting into 18F4331 from my base 16F877A.
I also have the portability issues. In case you have found your way out.
Kindly help me too.

Cheers

I got this information from the datasheet,

"VS --> Supply Voltage for the Power Output Stages.
A non-inductive 100nF capacitor must be connected between this
pin and ground."

and,

"VSS --> Supply Voltage for the Logic Blocks. A100nF capacitor must be
connected between this pin and ground."

As I see no capacitors in your schematic, possibly this is the reason for your worries.
