Problems solved by technology

[0004] The disadvantage of the existing keypad manufacturing method is that when manufacturing multiple types of keypads, the drivers corresponding to each keypad are different, and the different drivers corresponding to each keypad must be sequentially written into the memory of different types of keypads. , and each type of keypad corresponds to a different production process
Therefore, when manufacturing various types of keypads, it is necessary to change the production process frequently, resulting in a decrease in production efficiency and an increase in cost

Embodiment Construction

[0011] see figure 1 , is a structural schematic diagram of the keypad module of the present invention. The module includes: a keypad shell 10, which uniquely corresponds to a keypad identification ID used to identify the keypad type; a chip 20, which is shared by different types of keypads, and which is connected to the keypad shell 10 through an array. Lines 30, 31, 32 are connected. Wherein, the keypad housing 10 further includes two diodes 111, 112, the cathode of the diode 111 is connected with the cable 31, the cathode of the diode 112 is connected with the cable 32, the anode of the diodes 111, 112 is connected with the emitter of the triode 131, and the triode The base of 131 is connected to the chip 20 through the cable 30, and the collector is grounded. The chip 20 further includes a memory 21, which stores a number of keypad module shared drivers 210 and dedicated drivers 211, 212, 213, 214, wherein each dedicated driver corresponds to a different keypad identifica...

Abstract

A keypad module comprises a keypad shell corresponding only to ID for identification keypad type; a chip connects to keypad out shell; wherein, out shell comprises further some diodes with switching logic combination code corresponding only to ID; the chip comprises further a memory stored some keypad special driver corresponding only to ID and sharing driver programs; and a controller, connect to memory and used to activate corresponding driver in memory according to keypad identification ID. During preparation, controller in chip reads switching logic combination of diodes, activates drivers according the ID to realize special function of this keypad type.

Description

【Technical field】 [0001] The invention relates to a keypad module and a manufacturing method thereof. 【Background technique】 [0002] A keypad is a digital input device with a built-in driver, which realizes specific functions through user key input, and is often used in mobile phones, controllers and other equipment. [0003] The existing keypad manufacturing method is to write the driver program into the memory of the keypad to be manufactured, so as to realize the specific functions of this type of keypad. [0004] The disadvantage of the existing keypad manufacturing method is that when manufacturing multiple types of keypads, the drivers corresponding to each keypad are different, and the different drivers corresponding to each keypad must be sequentially written into the memory of different types of keypads. , and each type of keypad corresponds to a different production process. Therefore, it is necessary to frequently change the production process when manufacturin...
