Giro y velocidad de un motor CD con un PIC16F4550

Ssistemadonde mediante dos botones y un potenciómetro (POT) realice el giro ymodificación de velocidad de un motor de DC, con uso de un puente H.



He el codigo completo, pueden copiarlo e un .c , si no funciona soo creen un nuevo proyecto desde PICC
