Method for realizing multikey function on mobile phone by rotating key

Abstract

The invention relates to the field of communication, and discloses a method for realizing a multikey function on a mobile phone by a rotating key. The method comprises the following steps: the rotating key is arranged on the mobile phone; and in the keypress setting, the setting is as follows: the upper end of the rotating key corresponds to an upper direction key, the lower end of the rotating key corresponds to a lower direction key, the left and right ends of the rotating key correspond to left and right soft function keys respectively, the middle part of the rotating key corresponds to an OK key, the rotating key is connected with a rotation direction identification circuit, an output end of the rotation direction identification circuit is connected with a semi-conductor memory, an interrupt processing function for judging the rotation direction of the rotating key is written into the semi-conductor memory, the clockwise rotation of the rotating key corresponds to a left direction key, and the anticlockwise rotation of the rotating key corresponds to a right direction key. The method adopts the rotating key to realize multiple functions, and ensures that the space occupied by keypresses on the mobile phone is reduced and the circuit wiring is easy, thereby bringing a qualitative leap on appearance design and the expandability of circuit layout, and also reducing the production cost.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing multi-key functions by a rotary key. Background technique [0002] At present, domestic mobile phones usually adopt the traditional appearance design mode of four direction keys and two soft function keys. Since this design requires the use of multiple keys, it will not only cause certain difficulties in circuit wiring, but also become more and more difficult. As the mobile phone tends to be miniaturized, the space it occupies prevents the appearance design of the mobile phone from fully utilizing its scalability, resulting in that the user interface design of the mobile phone cannot keep up with the leading trend of the market. At the same time, its production cost will also increase the company's Cost expenditure, which will also greatly compress the market profits of enterprises.
