BaserK 2:073c5513e2de 27 * @description of the program:
BaserK 5:c1f954e2f00a 28 *
BaserK 2:073c5513e2de 29 * Brushless motor control program with L293D.
BaserK 2:073c5513e2de 30 * L293D is a simple, cheap standard DC motor driver and can be found easily.
BaserK 2:073c5513e2de 31 * But I should say that controlling brushless motors with L293D is not efficient
BaserK 2:073c5513e2de 32 * and precise. Proper way to control brushless motor is using an ESC or drivers
BaserK 2:073c5513e2de 33 * like L6235. For the time being I have none of them, but I had a brushless motor that
BaserK 2:073c5513e2de 34 * I wanted to control and see how it works. If you want to do the same, that program
BaserK 2:073c5513e2de 35 * is for you.
BaserK 2:073c5513e2de 36 *
BaserK 2:073c5513e2de 37 * This guy did a great job by explaining how it is done:
