hi.
I have a solar car project whose dc motor will be controlled (speed, forward-back controls) by pic 16f84. we don't have enough information and backround of PWM and pic 16f84 assembler. İf anybody knows assembler codes or etc. waiting for your responses.

I suggest that you use a H-Bridge for controlling your motor in all four quadrants
≡ forward,reverse,forward braking and reverse braking ≡ PWM will be applied to the switching of the transistors to control the speed.
I havent used pic but I know that some variants of pic do have PWM outputs in them. I used the timers in 8051 to generate the PWM in my project.
 

Btter use a PIC which has invuilt PWM, instead of trying to implement software PWM.

Search a little bit using google and you will your project already done !
