specific Embodiment 1

[0031] see Figure 1-2 , the present invention provides a technical solution: a button module with an optional touch mode, including a substrate 1 made of insulating material, and the substrate 1 is pasted with:

[0032] Touch buttons 2, including at least one touch type touch button 2, each touch type has at least two touch buttons 2;

[0033] The touch chip 3, the touch button 2 and the touch chip 3 are connected using the GPIO protocol to obtain the key code of the touch button 2;

[0034] A dial switch 4, the dial switch 4 is connected to the touch chip 3 for switching the touch type of the touch button 2;

[0035] It also includes an external main control chip 5, the touch control chip 3 is connected to the main control chip 5, and the effective signal processing module 5-1 is integrated and programmed on the main control chip 5, and the corresponding touch keys of each touch type key control program module 5-2.

[0036] The touch button 2 on the substrate 1 is a capac...

specific Embodiment 2

[0040] The difference between this embodiment and specific embodiment 1 is:

[0041] Such as image 3 As shown, the touch button 2 on the substrate 1 is a pressure touch button, and a touch spring 7 that can sense pressing and generate a corresponding pressing signal is provided under the corresponding touch button 2 on the substrate 1. 7 is connected to the touch chip 3, and an indicator light 8 is provided in the hollow inside the touch spring 7, and the indicator light 8 is connected to the touch chip 3, so that the user turns on and lights the indicator light 8 during the pressing process, Give users manipulation feedback;

specific Embodiment 3

[0043] Such as Figure 4 As shown, this embodiment combines specific embodiment 1 and specific embodiment 2. There are two sets of touch buttons 2 on the substrate 1 of this embodiment, one of which is pressure touch buttons and the other is capacitive touch buttons. Touch buttons, the user can select or switch one of the group of touch buttons 2 through the dial switch 4 for manipulation.

[0044] A touch module assembly communication method described in any one of the above, comprising the following steps:

[0045] S1. Turn on the power supply, and the touch chip 3 matches the main control chip 5 to establish a communication channel;

[0046] S2. Dial the DIP switch 4 to the position corresponding to the preselected touch type;

[0047] S3. The touch chip 3 reads the dial value of the dial switch 4, and sends the dial value to the main control chip 5 to select the touch program module 5-2 corresponding to the preset touch type;

[0048] S4. The main control chip 5 reads t...

Abstract

The invention discloses a key module with selectable touch modes and an assembly communication method of the key module; a touch key, a touch chip and a dial switch are patched on the substrate; the module also comprises an external main control chip. According to the key module, the dial switch is used; a main control chip integrated with various touch control type touch control program modules is combined; through the dial switch, the touch key of the preset touch type can be matched with the touch program in the main control chip. Therefore, a manufacturer only needs to patch materials of acorresponding touch type, the problem of control program burning errors is avoided; most importantly, the touch chip of the key module only has the functions of key signal processing and transmission, and all key control and execution functions are completed by the external main control chip, so that the software version of a touch program and the difficulty of program upgrading and maintenance are reduced.

Description

technical field [0001] The invention relates to the technical field of touch buttons, in particular to a button module with an optional touch mode and an assembly communication method thereof. Background technique [0002] Compared with traditional mechanical buttons, touch buttons have a better control feel and are durable; there are various types of touch buttons on the market, including capacitive touch, pressure touch, resistive touch, infrared touch, etc. . [0003] At present, most of the existing touch key boards only have one touch type of touch keys, and the touch mode is single; Signal touch chip, and finally the touch chip transmits the processed signal to the main control chip to obtain the key code and complete the response action, but it is not convenient for the upgrade and maintenance of the later program; in addition, the existing touch key board is because For the single use of the touch button type, only one touch program is burned into the chip. If mult...
