Abstract: A knob device is applicable to a touch panel. The knob device includes a knob cover; and a rotation sensing element. The rotation sensing element includes a base and a plurality of sensing pads connected to the knob cover. The rotation sensing element is arranged between the touch panel and the knob cover. The base is connected to the knob cover. When a user touches the knob device, the touch panel generates a rotation sensing signal in response to a location of the plurality of sensing pads. An orthographic projection of the knob cover on the touch panel is divided into a plurality of parts, the plurality of parts are distributed radially from a center of the orthographic projection of the knob cover, each sensing pad is located in a part and connected to another sensing pad located in another part adjacent to the part.

Abstract: A driver adaptable to a debugging system includes a driver controller, and a driver general-purpose input and output (GPIO) controlled by the driver controller. The driver GPIO directly transfers a debug log of status messages of a touchscreen to a host general-purpose input and output (GPIO) of a host without handshaking between the driver and the host.

Abstract: A calibration method and a calibration apparatus for a knob applicable to a touch panel are provided. The knob includes at least one sensing pad. The calibration method includes: obtaining sensed position(s) of each sensing pad by sensing a position of the sensing pad through the touch panel; and calculating a position of a center of the knob by using a formula of a radius of a circumscribed circle according the sensed position(s) of each sensing pad.

Abstract: A knob device is applicable to a touch panel. The knob device includes a knob cover, a plurality of sensing pads and a rotation sensing element. The plurality of sensing pads are fixedly arranged on the touch panel. A gap is form between two sensing pads. The plurality of sensing pads and gaps are distributed in a ring area around a center of an orthographic projection of the knob cover. The rotation sensing element is connected to the knob cover. When the knob cover is turned to be rotated, the rotation sensing element is rotated synchronously. When a user touches the knob device and the rotation sensing element overlaps one of the plurality of sensing pads, the touch panel generates a rotation sensing signal in response to a location of the rotation sensing element.
