Simple program used to calibrate AFRO ESC's from HobbyKing
Used to calibrate 4 ESC's at once. Connect each ESC's PWM input pin to p22, p23, p24, p25 respectively. This will calibrate the ESC's with a maximum PWM pulse width of 1860 and a minimum of 1060. These numbers can be changed to match your setup.
