Embodiment Construction
[0016] see Figure 1 to Figure 3 , figure 1 It is a schematic circuit diagram of the correction circuit 10 of the embodiment of the present invention, figure 2 The operation flowchart of the correction circuit 10 of the embodiment of the present invention, image 3 Schematic diagram of the waveform of the trigger signal S analyzed by the calibration circuit 10 of the embodiment of the present invention. The correction circuit 10 is preferably applied to an electronic device with buttons, such as a navigation device for a computer mouse, so as to improve the bouncing misjudgment of the buttons. The trigger signal S may be generated when the user presses the button or the button is affected by the vibration of the environment. The value change of the trigger signal S generated by pressing the button is usually relatively large, and the value change of the trigger signal S generated by the button being bounced by the environment vibration is generally small. The correction ci...
