schematic of a motor controller circuit using pic18f4331

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.. 18f4331 has additional PWM pins. what r they used for? I read the datasheet but couldnt figure them out. Can someone show me a schematic of a motor controller using pic18f4331 and a l298
