Abstract
A control system of a manual pulse generator for controlling a rotation speed and a rotation direction of a motor includes a touch panel, a timer, a coordinate calculation unit, and a wave generation unit. The touch panel receives a contact signal and generates an electrical signal according to the contact signal. The timer records the amount of time used to input the contact signal. The coordinate calculation unit calculates coordinates of each input point of the contact signal on the touch panel according to the electrical signal to determine direction of the contact signal and input speed for the contact signal. The wave generation unit generates a pulse signal to control the motor according to the direction of the contact signal and the input speed for the contact signal.
