Description

Technical Field

[0001] This invention relates to the field of integrated circuit chips, and in particular to a hot standby multicolor integrated circuit chip capable of transmitting and receiving control signals. Background Technology

[0002] Most circuits acquire several external control signals through the MCU's I / O ports, and use a matrix-based multiplexing method to make efficient use of the I / O ports. If LEDs need to be driven, external driver chips, transistors, or field-effect transistors must be added, requiring even more I / O ports.

[0003] For example, a keyboard with more than 100 keys, especially mechanical keyboards with GRB backlighting, magnetic switch keyboards with GRB backlighting, optical switch keyboards with GRB backlighting, and inductive keyboards with GRB backlighting, are basically double-sided boards, and some are even four-layer boards. They are expensive, have many components, complex processes, and many defective products. Summary of the Invention

[0088] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0089] Example 1

[0090] like Figure 1 ,8 A hot-standby RGB integrated circuit chip capable of transmitting and receiving control signals is disclosed. The RGB integrated circuit chip contains GRB LED beads and integrates a control signal interface circuit, a GRB RGB driving circuit, an address code memory, and a serial-parallel single-bus serial communication circuit. It includes control signal interface pins, a power supply pin, a ground pin, a parallel data line pin, an address code input pin, and an address code output pin. The power supply pin supplies power to the RGB integrated circuit chip, and the ground pin is used for signal grounding and power grounding. The address code memory stores the communication address code. The GRB RGB driving circuit drives the GRB LED beads through three PWM signals.

[0091] When the control signal interface pin is in input mode, it is used to receive external control signals. At this time, the control signal interface circuit is responsible for processing the external control signals and connecting them to the serial communication circuit of the serial bus. When the control signal interface pin is in output mode, the serial communication circuit of the serial bus outputs control signals to the control signal interface pin through the control signal interface circuit.

[0092] The address code input pins and address code output pins of n RGB integrated circuit chips are cascaded to form a series data line network DIN(1)-DOUT(n). The two ends of the series data line network DIN(1) and DOUT(n) are connected to the MCU respectively. The MCU writes the sequence number formed by the cascaded RGB integrated circuit chips into the address code memory through the series data line network DIN(1)-DOUT(n) and uses it as the communication address code. The power supply pins of the n RGB integrated circuit chips are connected in parallel to share the power supply network VCC, the ground pins are connected in parallel to share the ground network GND, and the parallel data line pins are connected in parallel to form a parallel data line network DIO, which is then connected to the MCU.

[0093] Serial-parallel single-bus serial communication circuits are used to process serial data line network information and parallel data line network information.

[0094] GRB RGB information and control information can be transmitted on the parallel data line network DIO;

[0095] GRB RGB information and control information can also be transmitted on the serial data line network DIN(1)-DOUT(n);

[0096] Both the parallel data line network DIO and the serial data line network DIN(1)-DOUT(n) use the serial single-bus communication protocol to transmit GRB color information and control information, and are hot backups for each other.

[0097] The control signal interface pins receive signals including electrical signals, optical signals, magnetic induction signals, switching signals, capacitive touch signals, and also digital signals from the MCU (such as...). Figure 13( ), or simulated voltage signal; in terms of physical connection, the control signal interface pins can be connected to phototubes, magnetic induction sensors, mechanical switches, and touch sensing devices.

[0098] The control signal interface circuit processes the signals received by the control signal interface pin. The pull-up resistor value connected to the control signal interface pin inside the integrated circuit chip can be set by the program, and different received signals are processed by the corresponding program circuit.

[0099] In practical applications, serial and parallel data line networks transmit data information simultaneously. GRB RGB information is transmitted on the serial data line network, while control information is transmitted on the parallel data line network. This improves the scanning frequency of devices containing integrated circuit chips (such as magnetic induction buttons) and the scanning frequency of GRB LEDs, aiming for maximum stability and reliability. Only in extreme cases where one fails, the data communication networks are switched intelligently and instantly.

[0100] Taking magnetic induction buttons as an example:

[0101] There are many forms of specific transmission protocols for data information on parallel data line networks (DIO). The Chinese invention patent "A magnetic induction integrated circuit chip with address code, key and magnetic induction keyboard" with announcement number CN120049875B gives a variety of different custom code sending methods and working methods. For those skilled in the art, the transmission methods are clear and feasible, and will not be elaborated here.

[0102] like Figure 18 ADD1 is the first magnetic induction integrated circuit chip, ADD2 is the second, and ADD3 is the third. ADD stands for ADDRESS. The data structure is: 16 bits of data from the first magnetic induction integrated circuit chip + 16 bits of data from the second magnetic induction integrated circuit chip + 16 bits of data from the third magnetic induction integrated circuit chip + ... + 16 bits of data from the nth magnetic induction integrated circuit chip + Trst; Trst = Time Reset bus reset time.

[0103] like Figure 19 The most significant byte comes first, followed by the least significant byte. The first 6 bits of the 16-bit data are the address command codes "A5, A4, A3, A2, A1, A0", followed by 10 bits of address codes "D9, D8, D7, D6, D5, D4, D3, D2, D1, D0", for a total of 10 bits, forming a total of 1024 address codes.

[0104] like Figure 18The first magnetic induction integrated circuit chip receives n 16-bit data, retains the first address code in the address code memory of the first magnetic induction integrated circuit chip, and transmits the second 16-bit data to the nth 16-bit data as is to the second magnetic induction integrated circuit chip.

[0105] The second magnetic induction integrated circuit chip receives n-1 16-bit data, retains the original second address code in the address code memory of the second magnetic induction integrated circuit chip, and transmits the third to nth 16-bit data to the third magnetic induction integrated circuit chip as is.

[0106] The third magnetic induction integrated circuit chip receives n-2 16-bit data, retains the third address code in the address code memory of the third magnetic induction integrated circuit chip, and transmits the fourth to nth 16-bit data to the fourth magnetic induction integrated circuit chip as is.

[0107] The nth magnetic induction integrated circuit chip receives a 16-bit data and stores the nth address code in the address code memory of the nth magnetic induction integrated circuit chip.

[0108] When the parallel data line network fails, the magnetic induction button information is switched to be transmitted on the serial data line network. At this time, the serial data line network acts as a backup data line for the parallel data line network, and its transmission process is as follows:

[0109] The magnetic induction button information code is defined to include the button command code and the button status code.

[0110] When the first magnetic induction integrated circuit chip receives the magnetic induction button information code, it simultaneously transmits the first bit of the button command code to the second magnetic induction integrated circuit chip when it receives the second bit of the button command code.

[0111] When the second magnetic induction integrated circuit chip receives the second bit of the key command code, it simultaneously transmits the first bit of the key command code to the third magnetic induction integrated circuit chip.

[0112] When the third magnetic induction integrated circuit chip receives the second bit of the key command code, it simultaneously transmits the first bit of the key command code to the fourth magnetic induction integrated circuit chip.

[0113] ...

[0114] When the nth magnetic induction integrated circuit chip receives the second bit of the key command code, it simultaneously sends the first bit of the key command code to the MCU through the address code output pin DOUT(n).

[0115] Specifically, such as Figure 20 Taking 1024 magnetic induction button information codes as an example, "M5, M4, M3, M2, M1, M0" are the button reading command codes, where M1 and M0 are the defined total number of buttons, which can be customized.

[0116] M1=0 and M0=0 represent 128 keys, meaning there are 128 bits after reading the key command code;

[0117] M1=0 and M0=1 represent 256 keys, meaning there are 256 bits after reading the key command code;

[0118] M1=1 and M0=0 represent 512 keys, meaning there are 512 bits after reading the key command code;

[0119] M1=1 and M0=1 represent 1024 keys, meaning there are 1024 bits after reading the key command code;

[0120] The first magnetic induction integrated circuit chip will receive 1030 bits of magnetic key data information in sequence;

[0121] The second magnetic induction integrated circuit chip will receive 1030 bits of magnetic key data information in sequence;

[0122] The third magnetic induction integrated circuit chip will receive 1030 bits of magnetic key data information in sequence;

[0123] The nth magnetic induction integrated circuit chip will receive 1030 bits of magnetic key data information in sequence;

[0124] To save time, when the first magnetic induction integrated circuit chip receives the M4 bit, it simultaneously sends the M5 bit to the second magnetic induction integrated circuit chip.

[0125] When the second magnetic induction integrated circuit chip receives bit M4, it simultaneously sends bit M5 to the third magnetic induction integrated circuit chip.

[0126] When the third magnetic induction integrated circuit chip receives bit M4, it simultaneously sends bit M5 to the fourth magnetic induction integrated circuit chip.

[0127] When the nth magnetic induction integrated circuit chip receives the M4 bit, it simultaneously sends the M5 bit to the MCU through the address code output pin DOUT(n).

[0128] G1023……G2, G1, G0 are initially set to 1024 return-to-zero codes of “1”.

[0129] like Figure 21 :

[0130] Code 0 indicates that the magnetic key has been triggered and is used as a placeholder for sorting;

[0131] 0# indicates that the magnetic key was not triggered, but there is a placeholder for the sequence, i.e., placeholder code 0;

[0132] Code 1 represents the initial code, indicating that the magnetic key has not been triggered and is not occupying a space;

[0133] When the first magnetic induction integrated circuit chip is not triggered by the corresponding magnetic button, the bit of G1023 must be set to placeholder 1#, that is, placeholder 1 code, indicating that the magnetic button has not been triggered, but there is a placeholder sequence.

[0134] When the second magnetic induction integrated circuit chip is triggered by the corresponding magnetic button, it first detects that the bit of G1023 is 0#, and the bit of G1022 is still the initial code 1. Therefore, the second magnetic induction integrated circuit chip can only occupy the bit of G1022. At this time, when the second magnetic induction integrated circuit chip is triggered by the corresponding magnetic button, the bit of G1022 must be set to 0. G1022 being 0 indicates that the button has been triggered and there is a placeholder in the sequence.

[0135] When the third magnetic induction integrated circuit chip is triggered by the corresponding magnetic button, it first detects that bit 1 of G1023 is occupied because there is no trigger; bit 0 of G1022 is occupied because there is a trigger. Therefore, the third magnetic induction integrated circuit chip can only occupy bit G1021 for sequencing. At this time, when the third magnetic induction integrated circuit chip is triggered by the corresponding magnetic button, bit G1021 must be set to 0.
