HBridge circuit driver

Does anyone have a good example of a Pic controled H-Bridge to control a motor.

I want to use PWM to control the speed and direction of a 12v DC motor. I suspect that the motor will draw up to 10A. I suspect that I will need to use N-Channel and P-Channel Mosfets. I have tryed one schematic, but it did not work, so I have been searching the net, and thought I would ask the experts
