[0028] Optionally, in the above embodiment of the present invention, the atmosphere light control chip is an E3731i chip.

[0029] Furthermore, in some embodiments of the present invention, the frame structure of the data to be sent and the received data includes: a preamble field, an address field, a PSI field, a command field, a valid information field and a CRC field.

[0030] Specifically, in this embodiment of the present invention, according to the frame structure based on the SIO interface defined by the atmosphere light control chip (taking the E3731i chip as an example), such as Figure 2 As shown, the frame structure of the data to be sent and the received data includes: Preamble (i.e. preamble field): 4 bits, fixed to 0b1010.

[0031] Address (i.e. address field): 10 bits, with a value range of 0x000 (broadcast) and 0x001 to 0x3EF (single node address). Upstream messages always contain the address of the sending device in the address field.

[0032] PSI (PSI field): 3 bits, indicating the length of the payload in bytes. Its value must match the expected value of each command. The PSI field values ​​are as follows:

[0038] Further, in some embodiments of the present invention, Figure 3 As shown, the transceiver control circuit 20 includes: a transmission control circuit 201 and a reception control circuit 202 .

[0039] Among them, the sending control circuit 201 controls the data signal interface SIO_P to interact with the atmosphere light control chip, and the sending control circuit 201 is used to send the data to be sent, wherein the data to be sent includes a data signal in Manchester encoding form; the receiving control circuit 202 controls the data signal interface SIO_P and the clock signal interface SIO_N to interact with the atmosphere light control chip respectively, and the receiving control circuit 202 is used to receive the received data, wherein the received data includes a data signal and a clock signal in non-return-to-zero encoding form.

[0040] It can be understood that in this embodiment of the present invention, the MCU uses the sending control circuit 201 to control the data signal interface SIO_P to interact with the atmosphere light control chip so as to transmit the data to be sent (i.e., the data signal in Manchester encoding form) to the atmosphere light control chip, and uses the receiving control circuit 202 to respectively control the data signal interface SIO_P and the clock signal interface SIO_N to interact with the atmosphere light control chip so as to receive the received data (i.e., the data signal and clock signal in non-return-to-zero encoding form) fed back by the atmosphere light control chip.

[0041] Specifically, in the above-mentioned embodiment of the present invention, the MCU and the ambient light control chip (taking the E3731i chip as an example) use the SIO interface 10 to send and receive data to realize different communication modes: 1) MCU sends data: Manchester encoding is used. Within one clock, the level jumps from low to high to indicate logic 1, and jumps from high to low to indicate logic 0. The high level range is VDD~VDD-0.7V, the low level range is 0~0.7V, and the VDD range is 4.5~5.5V. Specifically, when MCU sends data, only the data signal interface SIO_P is used to transmit data. There is no data transmitted on the clock signal interface SIO_N. The baud rate of the transmitted data is fixed at 2.4Mbps. The waveform of the transmitted data is as follows: Figure 4 As shown in the figure, in order to clearly and concisely illustrate the waveform diagram of the transmitted data, Figure 4 In the figure, other groups of transmission data not shown are represented by thick solid lines.

[0042] 2) MCU sends data: non-return-to-zero encoding (NRZ) is used. In one clock, a high level indicates logic 1, and a low level indicates logic 0. The high level range is VDD~VDD-0.7V, the low level range is 0~0.7V, and the VDD range is 4.5~5.5V. Specifically, when the MCU receives data, the data signal interface SIO_P transmits data, and the clock signal interface SIO_N transmits clock. The clock polarity is configurable. The waveform of the transmitted data is shown in the figure below. Figure 5 As shown in the figure, in order to clearly and concisely illustrate the waveform diagram of the transmitted data, Figure 5 In the figure, other groups of transmission data not shown are represented by thick solid lines.

[0043] Further, in some embodiments of the present invention, Figure 3 As shown, the transceiver FIFO circuit 30 includes: a transmit FIFO circuit 301 and a receive FIFO circuit 302 .

[0044] The transmission FIFO circuit 301 exchanges data with the transmission control circuit 201, and the transmission FIFO circuit 301 is used to cache the data to be transmitted; the reception FIFO circuit 302 exchanges data with the reception control circuit 202, and the reception FIFO circuit 302 is used to cache the received data.

[0045] It can be understood that in this embodiment of the present invention, the MCU uses the sending FIFO circuit 301 to interact with the sending control circuit 201 for data, for example, the sending control circuit 201 captures the data to be sent from the sending FIFO circuit 301, and the sending FIFO circuit 301 sends the data to be sent to the sending control circuit 201, and the MCU uses the receiving FIFO circuit 302 to interact with the receiving control circuit 202 for data, for example, the receiving control circuit 202 captures the received data from the receiving FIFO circuit 302, and the receiving FIFO circuit 302 sends the received data to the receiving control circuit 202.

[0046] Further, in some embodiments of the present invention, the controller 50 is used to trigger an interrupt request when the send FIFO queue of the send FIFO circuit 301 meets the interrupt trigger condition, and trigger a DMA request when the send FIFO queue of the send FIFO circuit 301 meets the DMA trigger condition, wherein the interrupt trigger condition includes that the send FIFO queue is empty, and the DMA trigger condition includes that the total amount of data in the send FIFO queue is less than or equal to a preset send threshold.

[0047] It can be understood that in this embodiment of the present invention, when the sending FIFO queue of the sending FIFO circuit 301 meets the interrupt triggering condition (that is, when the sending FIFO queue of the sending FIFO circuit 301 is empty), the MCU uses the controller 50 to trigger the interrupt request. At this time, the control circuit 201 is controlled to transmit the data to be sent to the atmosphere light control chip, and when the sending FIFO queue of the sending FIFO circuit 301 meets the DMA triggering condition (that is, when the total amount of data in the sending FIFO queue is less than or equal to the preset sending threshold), the MCU uses the controller 50 to trigger the DMA request. At this time, the control register 40 transmits the data to be sent to the sending FIFO circuit 301 for caching. In this way, the MCU can send data to the atmosphere light control chip.

[0048] Optionally, in the above embodiment of the present invention, the threshold corresponding to the empty sending FIFO queue and the preset sending threshold can be configured in the register 40 respectively.

[0049] Furthermore, in some embodiments of the present invention, the controller 50 is used to trigger an interrupt request when the receive FIFO queue of the receive FIFO circuit 302 meets the interrupt trigger condition, and trigger a DMA request when the receive FIFO queue of the receive FIFO circuit 302 meets the DMA trigger condition, wherein the interrupt trigger condition includes at least one of the receive FIFO queue being empty, the receive FIFO queue being full, and the receive FIFO queue overflowing, and the DMA trigger condition includes the total amount of data in the receive FIFO queue being greater than or equal to a preset receive threshold.

[0050] It can be understood that in this embodiment of the present invention, when the receiving FIFO queue of the receiving FIFO circuit 302 meets the interrupt triggering condition (i.e., the receiving FIFO queue of the receiving FIFO circuit 302 is empty, or the receiving FIFO queue of the receiving FIFO circuit 302 is fully loaded, or the receiving FIFO queue of the receiving FIFO circuit 302 overflows), the MCU uses the controller 50 to trigger an interrupt request, at which time, the receiving control circuit 202 is controlled to transmit the received data to the receiving FIFO circuit 302, or the receiving control circuit 202 is controlled to suspend the transmission of the received data to the receiving FIFO circuit 302, and when the receiving FIFO queue of the receiving FIFO circuit 302 meets the DMA triggering condition (i.e., the total amount of data in the receiving FIFO queue is greater than or equal to the preset receiving threshold), the MCU uses the controller 50 to trigger a DMA request, at which time, the receiving FIFO circuit 302 is controlled to transmit the cached received data to the register 40 for storage. In this way, the MCU receives data from the atmosphere light control chip.

[0051] Optionally, in the above embodiment of the present invention, the threshold corresponding to the empty receiving FIFO queue, the threshold corresponding to the full receiving FIFO queue, the threshold corresponding to the overflow receiving FIFO queue and the preset receiving threshold can be configured in the register 40 respectively.

[0052] Furthermore, in some embodiments of the present invention, the register 40 is also used to configure the working parameters of the communication module and read the status parameters of the communication module.

[0053] It can be understood that in this embodiment of the present invention, the register 40 can configure the working parameters of the communication module according to user needs, for example, configure the communication module enable, interrupt request enable, interrupt flag clear, DMA request enable, CRC field enable, valid information length of the sent data, the address of the sent data, the PSI of the sent data, the command to send data, the valid information of the sent data, etc. In addition, the register 40 can also read the status parameters of the communication module, such as reading the valid information of the received data, the module interrupt flag, whether the module is busy, whether the send and receive FIFOs are full / empty, whether the CRC check is incorrect, whether an error occurs in the module, etc.

[0054] Further, in some embodiments of the present invention, Figure 6 As shown, the communication module 100 further includes: a CRC check comparison circuit 60, wherein the CRC check comparison circuit 60 is used to perform CRC check on the data to be sent and the received data.

[0055] It can be understood that in this embodiment of the present invention, the MCU can also use the CRC check comparison circuit 60 to perform CRC check on the data to be sent and the received data. Specifically, the MCU can use the controller 50 to control the CRC check comparison circuit 60 to perform CRC check on the data to be sent, and can also use the controller 50 to control the CRC check comparison circuit 60 to perform CRC check on the received data.

[0056] Furthermore, in some embodiments of the present invention, the CRC check comparison circuit 60 is also used to transmit the CRC check result of the data to be sent to the controller 50, and transmit the comparison result between the CRC check result of the received data and the received CRC check result to the register 40.

[0057] It can be understood that in this embodiment of the present invention, after the CRC check comparison circuit 60 completes the CRC check of the data to be sent, the CRC check result of the data to be sent can also be transmitted to the controller 50, so that the controller 50 sends the CRC check result of the data to be sent together with the data to be sent to the sending FIFO circuit 301, and, after the CRC check comparison circuit 60 completes the CRC check of the received data, the comparison result between the CRC check result of the received data and the received CRC check result can also be transmitted to the register 40, so that the register 40 stores the comparison result of the CRC check of the received data together with the received data, and, it is convenient for the controller 50 to judge and control the module to enter the interrupt according to the user configuration and the comparison result of the CRC check.

[0058] Specifically, in the above-mentioned embodiment of the present invention, the CRC field of the data to be sent is calculated by the CRC check comparison circuit 60 itself, and the CRC field of the received data is compared by the CRC check comparison circuit 60 itself, and the comparison result is reflected in the register 40.

[0059] In summary, according to the communication module of the embodiment of the present invention, the transceiver control circuit controls the SIO interface to perform data interaction with the atmosphere light control chip, and the transceiver FIFO circuit performs data interaction with the transceiver control circuit to cache the data to be sent and the received data, and the register stores the data to be sent and the received data, and then, the controller performs data interaction with the transceiver FIFO circuit and the register respectively to transfer the data to be sent to the transceiver FIFO circuit for caching and transfer the received data to the register for storage. Thus, direct communication between the MCU and the atmosphere light control chip is realized through the communication module, which is conducive to the MCU to control the atmosphere light control chip in a timely and effective manner, and effectively reduces the MCU software load.
