Hello,

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?
