I am Anthony Clay. I am still developing the PICFlyer R/C system. I am currently adding extra features. One of them is an onboard DC motor controller. Has anyone seen any examples on accomplishing this using the PWM ports. My first thought is to simply use a MOSFET connected as a switch. But how would I go about incorporating features such as dynamic braking. Does anyone know of a website that discusses the fundamentals of electric motor controllers?
