Problems solved by technology

[0004] Therefore, the control system of the known wheel keyboard has disclosed that the time difference between the jump of a pair of bit signals (the value of the signal strength changes from 0 to 1) is used to judge whether the user turns the wheel keyboard up or down, that is, , the control system of the known jog wheel keyboard will continue to execute the action of judging whether another bit signal has a jump every time when any bit signal jumps up, if another bit signal When there is a jump, it is necessary to calculate whether the jump time difference of another bit signal meets the conditions defined when turning up or down. In this way, the control system of the known wheel keyboard needs to consume a lot of system resources. These complicated calculations and judgments increase the load on the system, and in this real-time processing system, the control and interpretation methods of the known rotary keyboard require a large number of calculations, which easily causes delays in output and reduces the speed of rotation. The sensitivity of the wheel keyboard violates the good intention of the wheel keyboard to facilitate users to quickly and massively shift the screen, and also weakens the spirit of "instant".

Embodiment Construction

[0014] Please refer to image 3 and Figure 4 , image 3 It is a schematic diagram of an embodiment of the wheel keyboard 10 of the present invention, Figure 4 for image 3 The position signal table that wheel keyboard 10 outputs. The wheel keyboard 10 is divided into a plurality of sensing areas 11-15, and each sensing area includes two sensors 11a, 11b-15a, 15b, and utilizes related principles such as gratings and corresponding sensing devices 16 to sense The rotation of the jog wheel relative to the sensing device 16 is detected. The rotary keyboard 10 includes a rotary wheel made of a circular sheet, and a sensing device 16 composed of two sensing groups 18 and 20 located at different positions. The wheel includes a plurality of sensing areas that are set separately. This embodiment shows five sensing areas 11-15, and the sensing groups 18, 20 are respectively connected to the first sensing areas 11-15 of the wheel keyboard 10. One sensor 11a-15a corresponds to the ...

Abstract

In the present invention, the rotary wheel keyboard exports the first bit data and the second position metadata separately, the control system consists of a microcontrolled chip which is electric-connected to the rotary wheel keyboard for fetching the first and the second bit data as well as to make them have phase comparison with former set of the first and the second bit data separately then to decide whether to output a state signal or not according to the compared result, and a storage which is electric-connected to the microcontrolled chip used to stove the first bit data and the second bit data.

Description

technical field [0001] The invention provides a control system and method of a wheel keyboard, especially a control system and method for determining the state of the wheel keyboard by comparing phases of digital data. Background technique [0002] At present, the performance of mobile phones is getting better and better, with faster processing speed, more memory capacity and more functions for the convenience of users. In order to meet the different needs of various types of consumers, mobile phone manufacturers are also willing to Utilize new technologies and techniques to add more options and functions to the mobile phones it manufactures. On the market, the pointer device used to control the up and down movement direction of the image screen of the mobile phone often uses two buttons that can move the screen in the up and down direction to control the up and down movement of the image screen. An indicator device for scrolling up and down has appeared. A wheel that can r...
