Need an assembly code based on PIC18f26j11 controller to control the angle of a stepper motor with the pwm technique. The motor expects a pulse every 20 ms. The width of the pulse dictates the angle of the motor arm. A pulse of 1.5 ms width sets the servo to neutral position (45 degrees) a pulse of [url removed, login to view] ms sets to 0 degrees and a pulse of [url removed, login to view] ms to 90 degrees. Two buttons should be employed to set the arm anywhere between 0 and 180 [url removed, login to view] button to decrease angle and one button to increase angle.
