REMOTE CONTROLLER AND OPTION CHECKING METHOD OF REMOTE CONTROLLER

摘要

The disclosed remote controller connects the capacitor to the horizontal line of the key matrix and uses the capacitor charge / discharge time to control the controller to check the option of the remote controller.;The remote controller according to the present invention switches the signal input port to the output port so that the battery power can be applied to the option checking unit consisting of a capacitor connected to the horizontal line of the key matrix, and then switches back to the input port after the set time, through the input port. The control unit checks the input option data and sets the remote controller according to the checked option to enable the remote control function.;Therefore, the present invention has the advantage that the key matrix can be configured more because no separate port is required for option checking.
