Bi-Directional Speed Controller cu revers

   Cablajul executat corect si piesele puse dupa schema, ESC-ul functioneaza din prima. Atentie la programare sa pastrati valoarea OSCCAL al PIC-ului care il programati !

    HEX-ul si codul sursa il gasiti AICI. 

   Inainte de programarea PIC-ului, salvati valoarea OSCCAL citind memoria PIC-ului si salvand valoarea de la adresa 0x3FF (click pe figura de mai jos; este un exemplu al valorii PIC-ului care l-am programat).

    

Simple RC Speed Controller

      It uses a 6 transistor H-bridge drive. Two PNP power transistors are used for the source side of the H-bridge and two NPN power transistors of complimentary characteristics are used for the sink side of the H-bridge. The bases of each sink-source pair are connected by a small NPN transistor. This allows just two lines to control the H-bridge drive. This allows forward, reverse and off control of the motor. Braking cannot be acheived with this type of H-bridge. Bipolar transistors are used because the efficiency required for this controller is low.
