The magnetic element makes a reciprocating up and down movement on the side of the magnetic induction element through the horizontal induction surface of the magnetic induction element, and the polarity of the north and south poles changes relative to the magnetic element, so as to output a digital high and low level change.

[0027] Another object of the present invention is achieved by the following technical solutions:

[0029] The sequence numbers of the magnetic keys of the mechanical keyboard are marked at the corresponding key positions. The user presses and holds the magnetic key used as an auxiliary key, and then presses a magnetic key or presses two or more magnetic keys in sequence. The pressed magnetic key is a numeric key, and the combined digital value is a sequence number, indicating that the magnetic key corresponding to this sequence number is pressed.

[0030] A mechanical keyboard includes a printed circuit board, an MCU is arranged on the printed circuit board, and further includes a plurality of the above-mentioned scissor keys.

[0031] The sequence numbers of the scissor keys of the mechanical keyboard are marked at the corresponding key positions. The user presses and holds the scissor key used as an auxiliary key, and then presses a scissor key or presses two or more scissor keys in sequence. The pressed scissor key is a numeric key, and the combined digital value is a sequence number, indicating that the scissor key corresponding to this sequence number is pressed.

[0032] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0033] 1. The integrated circuit chip of the present invention has an address code. All n keys are connected in parallel through only one data line. Each integrated circuit corresponding to a key has its own unique address code, which does not repeat with other address codes. Since each integrated circuit has its own unique address code corresponding to the key information, and the key information is connected in parallel independently, the failure of one integrated circuit does not affect other keys, and the reliability is better!

[0034] 2. The integrated circuit chip of the present invention has an address code, and all data information codes can also be modulated onto the power supply for transmission. Assuming that the basic working reference voltage is 3.3V, corresponding to the signal low level, when the signal is high level, the signal voltage can be modulated to 5V and superimposed on the reference voltage of 3.3V. That is to say, the high and low levels of the modulated signal correspond to 5V and 3.3V. For a suitable demodulation circuit, removing the reference voltage can obtain the actual required digital switch signals of 1 and 0; compared with the parallel connection of the data line, its network only has the power supply VCC and the ground GND network, and the PCB circuit is simpler.

[0035] Similarly, since each integrated circuit has its own unique address code corresponding to the key information, and the key information is connected in parallel independently, the failure of one integrated circuit does not affect other keys, and the reliability is better!

[0036] 3. The present invention uses a parallel data line for the magnetic induction circuit or modulates information onto the power supply network to transmit data information, which can save a large amount of wiring space compared with series cascading, and the design difficulty of the PCB is reduced again.

[0037] 4. The present invention integrates the magnetic induction circuit and the GRB color-changing drive circuit integrated circuit on one chip at the same time, reducing the number of components by at least more than half, and having 2 - 3 circuit networks, which is more convenient than cascading in series.

[0038] 5. The integrated circuit chip of the present invention has an address code and a higher transmission efficiency. For example, for integrated circuit chips with n or even hundreds of consecutive address codes, if it is required that all integrated circuits light up and have the same gray level, then a broadcast instruction code can be customized in a broadcast form, that is, directly using the broadcast instruction code + relative address code + GRB byte code, and the instruction is more convenient and efficient.

[0039] 6. The integrated circuit chip of the present invention has an address code and can directly operate on one or several integrated circuits with address codes, that is, directly using the direct instruction code + the natural sequence address code of the integrated circuit + GRB code, and the instruction is more simple and efficient.

[0054] The present invention will be further described in detail below in conjunction with embodiments and the attached drawings, but the implementation manners of the present invention are not limited thereto.

[0055] Embodiment 1

[0056] As Figure 1 , an integrated circuit chip with an address code, the integrated circuit chip containing a programmable address code; the integrated circuit chip integrating a magnetic induction circuit and a GRB color-changing driving circuit;

[0057] The integrated circuit chip includes a power supply pin, a ground pin, and a data pin. The power supply pin is used to supply power to the integrated circuit chip, and the ground pin is used for signal grounding and power grounding; the power supply pins of n integrated circuit chips are connected in parallel to share the power supply network VCC; the ground pins of n integrated circuit chips are connected in parallel to share the ground network GND, and the data line pins of n integrated circuit chips are connected in parallel to share the data line network DIO and are connected to the MCU; the data information of the integrated circuit chip is modulated and transmitted on the data line network DIO; the sequence position of the integrated circuit chip on the PCB is written into the address code of the corresponding integrated circuit chip, and the cycle sequence of the data information code sent by the MCU after the address code corresponds one-to-one with the sequence position of the integrated circuit chip on the PCB, that is: Figure 4 In, the T1 time cycle sequence of the data information code cycle sequence bit 1 sent by the MCU after the address code corresponds to the integrated circuit chip at sequence position 1 on the PCB, the T2 time cycle sequence of the data information code cycle sequence bit 2 sent by the MCU after the address code corresponds to the integrated circuit chip at sequence position 2 on the PCB, and the T3 time cycle sequence of the data information code cycle sequence bit 3 sent by the MCU after the address code corresponds to the integrated circuit chip at sequence position 3 on the PCB.

[0058] As Figure 2, there are 3 integrated circuit chips with address codes connected in parallel to form a whole column, forming a VCC network, a ground GND network, and a data line DIO network; all the same network names are electrically connected together. The 3 integrated circuit chips with address codes are ranked as chip 1, chip 2, and chip 3 from left to right in the coordinate system. The first magnetic element 61 will move from beginning to end above each integrated circuit chip with an address code according to a custom sequence position. When the first magnetic element 61 moves above the integrated circuit chip of rank 1, the chip of rank 1 senses a voltage change through magnetic induction. At the same time, the chip of rank 1 receives an address code instruction and address code 1, and then saves the number 1 as the address code. Then, when the first magnetic element 61 moves above the integrated circuit chip of rank 2, the integrated circuit chip of rank 2 senses a voltage change through magnetic induction. At the same time, the integrated circuit chip receives an address code instruction and address code 2, and then saves the number 2 as the address code. Again, when the first magnetic element 61 moves above the integrated circuit chip of rank 3, the integrated circuit chip of rank 3 senses a voltage change through magnetic induction. At the same time, the integrated circuit chip receives an allocated address code instruction and address code 3, and then saves the number 3 as the address code. In this way, we have completed the regular natural sequence address codes for the chips of rank 1, rank 2, and rank 3. The natural sequence address codes greatly facilitate information communication, and the same applies to n integrated chips.

[0059] Furthermore, the integrated circuit chips with address codes also have their own UID identification codes. When the first magnetic element 61 acts on the integrated circuit chip with an address code, it first reads the UID code of the chip, and then returns the UID code and the address code together and outputs them to the chip. The chip compares its own UID code. If they are the same, it correctly saves the address code; otherwise, it does not write, which can greatly improve the reliability of writing the address code.

[0060] After the address code is allocated, the custom-developed machine or MCU can rely on the custom instruction code to sequentially read the sequence address codes of each chip. If they are not correctly written, they are written again to ensure the uniqueness and correctness of the address code.

[0061] Such as Figure 3 、 4 , the data line DIO has a weak pull-up resistor R = 1K. The 3 integrated circuit chips with address codes are sequentially chip 1, chip 2, and chip 3 from left to right.

[0062] Such as Figure 4 , only the chip with address 2 is affected by the fourth magnetic element 102. Here, for the sake of the narrative of the logical relationship, it is assumed that the integrated circuit chips with address codes not affected by the magnetic element are in the logical 1 state, and the integrated circuit chips with address codes affected by the magnetic element are in the logical 0 state.

[0063] According toFigure 5 According to the 0-code regulation shown, the typical value of TOH1 is 1 / 4Tt, and the typical value of TOL1 is 3 / 4Tt; according to Figure 5 the 1-code regulation shown, the typical value of TOH2 is 3 / 4Tt, and the typical value of TOL2 is 1 / 4Tt. Figure 4 In it, in the T2 time sequence code, there are a total of 6 time nodes, namely T20, T21, T22, T23, T24, and T30. DIO_TX and DIO_RX are the waveforms of the same data line at the same moment. Theoretically, it is the DIO_TX waveform. However, due to the action of the fourth magnetic element 102 on the chip with address code 2, only the DIO_RX waveform can be seen on the oscilloscope. The following is the whole process of the change of the button waveform: The MCU gives a complete button information code cycle, the bus reset code RESET, the instruction code CMD for obtaining the button information, then gives a starting address code ADDR1, and then gives the 3-bit button information code after the starting address code ADDR1 on the DIO_TX line as shown in Figure 4 and focuses on describing the change process of the button high and low levels on the DIO_TX.

[0064] In actual operation, we do not need to set the address code of the corresponding integrated circuit chip before obtaining each button information code. We only need to give the starting address code, Figure 4 and the DIO_TX waveform in it is like this. The starting address code is 1. After the starting address code, there are the first time sequence cycle T1, the second time sequence cycle T2, and the third time sequence cycle T3 respectively.

[0065] The address code corresponding to the integrated circuit chip in sequence position 1 is 1, corresponding to the first time sequence cycle T1. The integrated circuit chip in sequence position 1 is not affected by the third magnetic element 101. The integrated circuit chip in sequence position 1 is in the logic 1 state, and the chip in the logic 1 state does not make any change to the waveform of DIO_TX within the T1 cycle. In the time sequence cycle T1, DIO_RX can read Figure 5 the 1-code shown.

[0066] The MCU control unit outputs a weak pull-up level on the DIO_TX at the T10 moment and detects that the output weak pull-up level has not changed at the T12 moment. At this point, the MCU control unit reads the Figure 5 1-code shown output by the integrated circuit with the DIO_RX address code 1, indicating that the button switch in sequence position 1 is not pressed. The MCU control unit outputs a low level at the T13 moment until the T20 time node.

[0067] The address code corresponding to the integrated circuit chip of sequence position 2 is 2. The integrated circuit chip of sequence position 2 corresponds to the time series cycle T2. The integrated circuit chip of sequence position 2 is affected by the fourth magnetic element 102, and this chip is in the logic 0 state. The integrated circuit chip of sequence position 2 in the logic 0 state pulls down the high level of DIO_TX at the moment T21 within the corresponding T2 cycle and keeps it until the moment T24. The integrated circuit chip of sequence position 2 changes the Figure 5 shown 1 code into the Figure 5 shown 0 code on DIO_RX. Within the time series cycle T2, the 0 code shown in Figure 5 can be read on DIO_RX.

[0068] The MCU control unit outputs a weak pull-up high level on DIO_TX at the moment T20, and detects that the output weak pull-up level becomes low at the moment T22. Thus, the MCU control unit reads the Figure 5 shown 0 code output by the integrated circuit of sequence position 2 of DIO_RX, indicating that the key switch of sequence code 2 is pressed and recognized. The MCU control unit outputs a low level at the moment T23 until the time node T30. The moment T23 is a little earlier than the moment T24.

[0069] The address code corresponding to the integrated circuit chip of sequence position 3 is 3. The integrated circuit chip of sequence position 3 corresponds to the time series cycle T3. The integrated circuit chip of sequence position 3 is not affected by the fifth magnetic element 103, and this chip is in the logic 1 state. The integrated circuit chip with address code 3 in the logic 1 state does not make any change to the waveform of DIO_TX within the T3 cycle. Within the time series cycle T3, the 1 code shown in Figure 5 can be read on DIO_RX.

[0070] The MCU control unit outputs a weak pull-up level on DIO_TX at the moment T30, and detects that the output weak pull-up level has not changed at the moment T32. Thus, the MCU control unit reads the Figure 5 shown 1 code output by the integrated circuit of sequence position 3 of DIO_RX, indicating that the key switch of address code 3 is not pressed. The MCU control unit outputs a low level at the moment T33 until the end of the time series cycle T3.

[0071] The key information of the integrated circuit chip of sequence position 1 corresponds to the timing cycle T1, the key information of the integrated circuit chip of sequence position 2 corresponds to the timing cycle T2, and the key information of the integrated circuit chip of sequence position 3 corresponds to the timing cycle T3. That is to say, T1, T2, and T3 can be output continuously and respectively correspond to the key information of the integrated circuit chips with address codes 1, 2, and 3, without adding their respective address codes before their respective key information respectively.

[0072] To summarize: When all integrated chips are arranged in an array on the PCB board, they are sorted one by one into a natural number sequence of 1, 2, 3... n. The address code of the integrated circuit chip ranked 1 is written as 1, the address code of the integrated circuit chip ranked 2 is written as 2, the address code of the integrated circuit chip ranked 3 is written as 3, and the address code of the integrated circuit chip ranked n is written as n. Such a one-to-one correspondence facilitates the MCU to operate on them conveniently and correctly; for the operation of n consecutive integrated circuit chips, the MCU only needs to give a starting address code after the operation command, and then sequentially give T1, T2, T3... Tn information code timing cycles. At this time, the starting address code is set to 1, indicating that the operation starts from the first integrated circuit chip. The data information of the first timing code cycle T1 is the information output to the first integrated circuit chip, the data information of the second timing cycle T2 is the information output to the second integrated circuit chip, the data information of the third timing cycle T3 is the information output to the third integrated circuit chip, and the data information of the nth timing cycle Tn is the information output to the nth integrated circuit chip;

[0073] After the magnetic parameter command, T1, T2, T3... Tn represent the magnetic parameter code timing cycles; after the RGB color-changing command code, T1, T2, T3... Tn represent the color gray scale code GRB timing cycles; after the instruction code for obtaining key information, T1, T2, T3... Tn represent the key information code timing cycles;

[0074] In this way, the sequence position of the integrated circuit chips in the PCB board space is in one-to-one correspondence with the timing cycles of the data information in terms of time through the starting address code; each integrated circuit chip corresponds to a key, and the operation on the integrated circuit chip corresponds to the operation on the key.

[0075] The working process of a complete information code total cycle:

[0076] A complete GRB color-changing coding cycle (such as Figure 6 ) plus a complete magnetic parameter coding cycle (such as Figure 7 ) plus a complete key information code cycle (such as Figure 8 ) is a complete information code total cycle. The address codes corresponding to n integrated circuit chips with address codes are the natural sequence 1, 2, 3... n. You can use this address code as a direct address code, that is, add a data cycle code timing after specifying 1 address code, that is, there is an address code after the custom instruction code, and there is a corresponding data information code cycle after this address code, that is, there is a corresponding address code before each data information code cycle; for example, for one or several discontinuous address codes corresponding to a certain RGB color-changing coding or magnetic parameter coding separately, this method can be used.

[0077] In most cases, the address code after the instruction code is used as the starting address code. That is, after this starting code address, the timing of n consecutive data information code cycles is sent continuously. The order of the data information code cycles sent by the MCU after the address code corresponds one by one to the order of the integrated circuit chips on the PCB. That is, the data information code cycle timing T1 corresponds to the integrated circuit chip order 1, the data information code cycle timing T2 corresponds to the integrated circuit chip order 2, the data information code cycle timing T3 corresponds to the integrated circuit chip order 3, and the data information code cycle timing Tn corresponds to the integrated circuit chip order n. Operating on n whole integrated circuit chips or operating on dozens of consecutive integrated circuit chips is more commonly used. At this time, as long as the instruction code gives the starting address code, it is not necessary to list all the address codes of the natural order one by one after the instruction code.

[0078] Suppose the starting address code is 1. At this time, there are n key information codes. Subtracting this starting address code from the corresponding address code of the integrated circuit chip can find its own corresponding position among the n codes. According to this rule, the first code corresponds to the first integrated circuit chip, the second code corresponds to the second integrated circuit chip, the third code corresponds to the third integrated circuit chip, and so on. The nth code corresponds to the nth integrated circuit chip. Such an instruction code form is more efficient.

[0079] Another example, suppose the starting address code is 51. At this time, there are 50 key information codes. According to this rule, the first code corresponds to the 51st integrated circuit chip, the second code corresponds to the 52nd integrated circuit chip, and the third code corresponds to the 53rd integrated circuit chip. This instruction code performs corresponding operations on the 51st to 100th integrated circuit chips.

[0080] Another example, if it is required that all the integrated circuits light up with the same gray level, then a broadcast instruction code is customized in a broadcast form, that is, directly using the broadcast instruction code with the GRB byte code is sufficient, and no address code is required; another example, if it is required that all the integrated circuit chips have the same magnetic parameter setting, then a broadcast instruction code is customized in a broadcast form, and directly using the broadcast instruction code with the magnetic parameter code is sufficient, and no address code is required. This broadcast instruction code without an address code is more convenient and efficient.

[0081] If the PC is in the sleep mode, the MCU can give an instruction code to all the integrated circuit chips to make all the integrated circuit chips sleep and enter the interrupt wake-up mode. At this time, if a key is pressed, the interrupt reporting mode is started. The interrupt reporting mode uses the method of the address code with the key code to be actively reported by the integrated circuit chip itself, so the power consumption is lower. When the keyboard is not used for a long time, the MCU can, according to the actual situation, make the integrated circuit chips enter this mode at any time or exit this mode at any time.

[0082] The integrated circuit chip is preferably a unipolar magnetic induction circuit chip; a unipolar Hall chip, a unipolar magnetoresistive chip AMR, GMR, TMR.

[0083] Such as Figure 9 , the second magnetic element 81 is above the integrated circuit chip 82 side, the N pole of the second magnetic element 81 is close to the S pole induction surface of the magnetic induction integrated chip 82. At this time, the magnetic induction integrated chip 82 is not affected by the second magnetic element 81. Assuming that the magnetic induction integrated chip 82 outputs a high level at this time;

[0084] Such as Figure 10 , when the second magnetic element 81 moves to Figure 8-2 position, at this time the second magnetic element 81 passes through the horizontal induction surface of the magnetic induction integrated chip 82. The S pole of the second magnetic element 81 acts on the S pole on the surface of the magnetic induction integrated chip 82, and the N pole of the second magnetic element 81 acts on the N pole on the surface of the magnetic induction integrated chip 82. At this time, the magnetic induction integrated chip 82 outputs a low level;

[0085] In short, for the unipolar chip 82 of the integrated circuit with an address, due to its unipolar magnetic induction principle, as long as the polarity of the magnetic element 81 acting on it changes relatively, the output level will surely change. Utilizing this characteristic, a highly reliable complete high and low level conversion signal can be obtained as the key switch signal.
