Touch program generation method and device

The invention relates to a program generation method, in particular to a program generation method of a touch switch.

In recent years, various electronic devices, including push-button switches on mobile phones, notebook computers, large-sized machines, home appliances, and the like, have gradually abandoned traditional buttons and been replaced by touch switches. In fact, even the widely used touch panel can be regarded as a large number of touch switch assemblies disposed on the display, because the principle is the same as the touch switch.

Touch switches are mainly divided into capacitive (capacitance) and resistive (resistance). Taking a capacitive touch switch as an example, a capacitive switch requires only one electrode to operate, and an electrode is disposed behind a non-conductor panel made of wood, glass, or plastic. The touch switch operates according to the body capacitance. When a person or a touch device touches it, the capacitance is increased to cause a change in the capacitance value. When the capacitance change value reaches or exceeds a predetermined threshold, the switch is judged. Triggered by being pressed. Regarding the above-mentioned touch or not, the judgment is performed by the software programmed in the IC, that is, the touch program.

As for the resistive touch switch, two electrodes are required, and the resistance value is changed as a basis for judging whether or not the contact is made. The main difference between the two types of touch switches is that the resistive type needs to be directly pressed to be triggered, but the capacitive type can be triggered by indirect pressing. Although the two principles are different, the touch program is also required to handle the touched or not. Judgment.

In the manufacturing process of the touch switch, the material structure and circuit wiring of the product mechanism will affect the discrete capacitance value or resistance value of the environment. Therefore, the touch program needs to be tailor-made according to the difference of individual products. Touch program. In the past, the program development method was to manually fill in the input value of the touch terminal. In the absence of relevant data or the data of the previous product could not be used, the developer could only try to make mistakes every time he processed the new product. Method test input value Is it right to get the best touch sensitivity? Moreover, each different circuit layout and material will affect the sensitivity, so that the parameters have to be re-adjusted. If the cause of the lack of sensitivity is not the program but other factors, it will waste more development time, not only the efficiency is more likely to delay the time-to-market of the product.

The following drawings and detailed description are provided to facilitate an in-depth understanding of the advantages of the present invention: refer to the first figure, which is a structural diagram of an embodiment of the touch program generating apparatus of the present invention. The touch program generating device 1 includes a touch switch 11, a calculation unit 12, and a program editing unit 13. The touch switch 11 can be a capacitive or resistive touch switch, and can generate a plurality of sensing variations through user triggering. The touch switch 11 is also the object of operation of the touch program. The touch program generated by the present invention is designed to enable various touch switches of different materials and circuit designs to perform functions smoothly, so that each time a new one is generated. The touch switch 11 can be replaced before the touch program.

The computing unit 12 is connected to the touch switch 11.

Setting parameters. In addition, in order to facilitate the operation of the touch program, the program editing unit 13 can set the touch program input value to a sensing range value, so that the sensing range value can be used as a basis for determining whether the touch switch 11 is triggered. When the program editing unit 13 has the touch program input value and the touch program parameter that meet the requirements, it can generate a touch program that meets the needs.

In addition, the touch program generating device of the present invention further includes a compiling unit 14 connected to the program editing unit 13, and can compile the touch program input value and the touch program related information such as the touch program parameter into a burning program. files. As for the programming unit 15 connected to the compiling unit 14, the compiled burning file is burned to an integrated circuit (IC) 16. The touch program generating device 1 is connected or includes an operation interface 17 in addition to being capable of displaying the capacitance or resistance change waveform of the touch switch 11, and is capable of displaying the touch program parameters. And the details of the steps such as whether to burn the integrated circuit or construct the intermediate file.

In a specific case, the computing unit 12, the program editing unit 13, the compiling unit 14, the programming unit 15, and the operation interface 17 of the present invention may be connected to each other independently, or two or more of the above five components. The combination is a device or an element as long as it can perform the same functions as those described above and can perform the method disclosed in the present invention. And the connection relationship of the above 12~15 and 17 components can also be adjusted according to specific needs. In other words, any device capable of performing the method of the present invention is within the scope of the present invention.

In addition, according to the first figure, the calculation unit 12, the program editing unit 13, the compiling unit 14, and the burning unit 15 belong to the working part 1A in the touch program generating apparatus 1, and the working part 1A can be connected or include the operation interface 17. The touch switch 11 and the integrated circuit 16 are included in the touch portion 1B. Generally, a touch unit 1B further includes a touch circuit (not shown) and touch buttons made of different materials (not shown).

Please refer to the second figure, which is a flowchart of an embodiment of a touch program generating method of the present invention. First, after the touch switch 11 and the programmable integrated circuit 16 to be developed are connected to the touch program generating device 1, the touch program generating device 1 reads the IC description file of the integrated circuit 16, and the user can The touch program parameter value is set via the operation interface 17 connected or included by the touch program generating device 1 (step 21), and the touch program parameters include a button material of the touch switch, a number of touch switches, an integrated circuit package form, and The setting parameters necessary for the operation of the touch program such as the integrated circuit transmission format. The number of touch switches is set to, for example, one and the integrated circuit transmission format is, for example, UART_TEST (test mode). After the setting is completed, an intermediate file is created (step 21A), the hardware code is combined with the intermediate file (step 21B), and then the original low-level programming language is compiled via the compiling unit 14 to generate an IC burning file (step 22). The burn-in unit 15 is used to burn the burn-in file to an integrated circuit 16 (step 23). The above steps 21 to 23 are simply steps of setting the touch program parameters and burning the touch program parameters to the integrated circuit 16.

Next, the touch program generating device 1 determines whether the integrated circuit transmission format is the test mode (step 24). If YES, the user enters the test step of triggering the touch switch, and the finger or the rule is pressed. Various triggering means such as pressing are used to trigger the touch switch, and a plurality of sensing variations are generated (step 25). The calculating unit 12 scales the inductive changes according to a specific calculation formula to obtain a magnification parameter (step 26), calculates a new inductive change amount according to the magnification parameter (step 27), and then selects the magnification parameter and the new inductive variation to set The touch program enters a value (step 28).

The specific calculation formula employed by the calculation unit 12 in the above step 26 is, for example, the following:

In the above formula, the scale parameter (Scale) is the quotient of any sensed change amount (Offset_count) divided by the arithmetic mean of the sensed change amounts (AVG_Offset). Generally, in order to adjust the sensitivity of the touch switch, the sense change amount may be In addition, an additional amount of inductive compensation (Sensivity_Compensate) is added, and the arithmetic mean of the induced variations is removed to calculate the magnification parameter. Therefore, the arithmetic mean of the amount of induced changes is proportional to the amount of induced changes.

In addition, in order to facilitate the programming language, the magnification parameter is preferably an integer, but the calculation according to the above formula does not guarantee that the magnification parameter must be an integer, which leads to the problem that a wider sensing range value cannot be defined. For example, when the magnification parameter is 1.336, but it can only be described by an integer such as 1 or 2, the amount of induced change after mathematical operation may be too far from the actual value, resulting in an oversensitive or insensitive condition. . Therefore, the present invention can obtain a non-integer magnification parameter (for example, 1.336) according to the above formula, and then set it to an approximate integer, such as 1 and 2, and then multiply the inductive changes by using a magnification parameter having a value of 1 and 2. The product of the arithmetic mean of the quantity is used to push back the new sensing variation as the basis for setting the touch input value. Since the above formula is an inequality, a better new sensing variation with a range can be obtained, and the new sensing variation can be further selected by the user or via the touch program generating device 1 according to the preset touch. The relevant conditions such as the control program parameters are selected to select the preferred values.

After obtaining the new sensing change amount and the magnification parameter through the above steps, the touch input value can be set as a touch input value, and the touch input value is used in the touch program as a judgment basis for whether the touch switch is triggered. And set the touch program parameters again. After the steps 24~28, the touch input value has been tested and set, so the transmission format of the integrated circuit 16 does not need to be set to the test mode (for example, changed to UART), and then steps 21~23 are repeated, that is, the touch is set. Control the program parameters, generate a touch program with a better new inductive change value and magnification parameter via the program editing unit 13, generate an IC burning file by the compiling component 14, and then IC The burn-in file is burned to the integrated circuit 16. Since the integrated circuit 16 is not in the test mode, the step of testing the switch is not required, but the product development is completed, and the touch program used by the touch switch is terminated. .

The embodiments described above are merely illustrative of the principles of the invention and its advantages, and are not intended to limit the invention. Therefore, those skilled in the art can make modifications and changes to the embodiments described above without departing from the spirit and scope of the invention.
