Description

Technical Field

[0001] This application relates to the field of data transmission technology, specifically to a serial transmission processing method, apparatus, storage medium, and electronic device. Background Technology

[0002] In serial transmission via the Serial Peripheral Interface (SPI), the host typically needs to transmit the data to the display device through the SPI bus. Currently, there are situations where, with the continuous upgrading of the host (such as the main control MCU or ARM processor), it may no longer support certain standard SPI modes, thus rendering display devices using unsupported standards unusable. For example, if the upgraded host only supports the four-wire standard SPI mode and not the three-wire 9-bit SPI mode, then display devices supporting the three-wire 9-bit SPI mode cannot be used on the host platform.

[0003] Currently, the existing technologies achieve compatibility between different Serial Peripheral Interface (SPI) modes by adding digital circuits or configuration registers, but the number of compatible display devices is limited. The current approach suffers from high serial transmission costs and a limited number of compatible display devices. Summary of the Invention

[0004] This application provides a serial transmission processing scheme that can achieve compatible serial transmission of different Serial Peripheral Interface (SPI) modes at low cost without increasing hardware costs, and can be compatible with more display devices with different serial peripheral interface modes.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0036] Figure 1 A flowchart illustrating a serial transmission processing method according to an embodiment of this application is shown. The subject executing this serial transmission processing method can be any host, such as a main control MCU or an ARM processor.

[0037] The serial transmission processing method is applied to a host computer that supports the interface mode of a first serial peripheral interface, such as... Figure 1 As shown, the serial transmission processing method may include steps S110 to S140.

[0038] Step S110: Receive serial content to be transmitted, wherein the content format of the serial content to be transmitted is a first serial format corresponding to a first serial peripheral interface; Step S120: Identify the serial content to be transmitted to obtain the content type of the serial content to be transmitted; Step S130: Convert the serial content to be transmitted into content that conforms to the first serial format and is compatible with a second serial format according to the content type, to obtain converted serial content, wherein the second serial format is the format corresponding to a second serial peripheral interface; Step S140: Send the converted serial content to a target device through the first serial peripheral interface, wherein the target device is a device that supports the interface mode of the second serial peripheral interface.

[0039] The serial content to be transmitted is the content to be transmitted to the target device. The serial content to be transmitted can be a command or data (data can also be parameters). The host supports the interface mode of the first serial peripheral interface, and the serial content to be transmitted received by the host is the first serial format corresponding to the first serial peripheral interface.

[0040] For example, the first serial peripheral interface supported by the host is a four-wire standard serial peripheral interface, and the serial content to be transmitted received by the host is the first serial format (i.e., the four-wire standard format) corresponding to the four-wire standard serial peripheral interface.

[0041] The host can identify the serial content to be transmitted and obtain the content type of the serial content to be transmitted. The content type can usually be a command type or a data type.

[0042] The host can convert the serial content to be transmitted into content that conforms to the first serial format and is compatible with the second serial format, based on the content type, to obtain the converted serial content. The second serial format is the format corresponding to a second serial peripheral interface, such as a three-wire, 9-bit serial peripheral interface.

[0043] The converted serial content conforms to the first serial format and is compatible with the second serial format. Therefore, the converted serial content can be transmitted by the host through the first serial peripheral interface bus, and the converted serial content can also be recognized by devices that support the interface mode of the second serial peripheral interface.

[0044] Furthermore, the host can successfully send the converted serial content to the target device that supports the interface mode of the second serial peripheral interface through the first serial peripheral interface, and the target device can recognize the converted serial content according to the interface mode of the second serial peripheral interface. This ensures that the platform of the host supporting the interface mode of the first serial peripheral interface is compatible with the target device supporting the interface mode of the second serial peripheral interface.

[0045] In this way, based on steps S110 to S140, the host can reassemble the received serial content to be transmitted into content that conforms to the first serial format and is compatible with the second serial format according to the content type. Then, the reassembled and converted serial content is sent to the target device through the first serial peripheral interface, so that the target device that supports the interface mode of the second serial peripheral interface can extract the content from the converted serial content. In this way, the host that supports the interface mode of the first serial peripheral interface can easily be compatible with target devices with different interface modes of the second serial peripheral interface. It can achieve compatible serial transmission of different serial peripheral interface (SPI) modes at low cost without increasing hardware costs and can be compatible with more display devices with different serial peripheral interface modes.

[0046] The following description Figure 1 Further optional specific embodiments for each step performed during serial transmission processing in the example.

[0047] In one embodiment, identifying the serial content to be transmitted and obtaining the content type of the serial content to be transmitted may include: obtaining the content type feature corresponding to the serial content to be transmitted based on the serial transmission mode corresponding to the first serial peripheral interface; obtaining the content type of the serial content to be transmitted based on the content type feature, wherein the content type includes command type or data type.

[0048] Different serial transmission methods typically have corresponding characteristics that reflect the type of content being transmitted. Content type characteristics are those that reflect the type (command type or data type) of the transmitted content. Based on the serial transmission method corresponding to the first serial peripheral interface, the content type characteristics of the serial content to be transmitted can be obtained, and the content type of the serial content to be transmitted can be determined from these characteristics.

[0049] Taking a serial peripheral interface with a four-wire standard as an example, such as Figure 2 As shown, the bus 200 of a four-wire standard Serial Peripheral Interface (SPI) typically includes a D / C communication line 210. In the serial transmission mode of the four-wire standard SPI, a low level on the D / C line indicates that the transmitted content is a command, and a high level on the D / C line indicates that the transmitted content is data. Therefore, the content type characteristic can be determined by whether the D / C line is high or low. Furthermore, based on whether the D / C line is high or low, it is possible to determine whether the content type is a command type or a data type.

[0050] Furthermore, such as Figure 2 As shown, the bus 200 of the four-wire standard Serial Peripheral Interface (SPI) may also include a clock line (SCLK: Serial Clock) 220, a control line (CS) 230 for controlling transmission enable and disable, a write data line (MOSI) 240 for the host to write data to the target device (e.g., an LCD display device), and a read data line (MISO) 250 for the host to read data.

[0051] For further details, please refer to [link / reference]. Figure 3The three-wire 9-bit standard Serial Peripheral Interface (SPI) bus 300 may include a clock line (SCLK: Serial Clock) 310, a control line (CS) 320 for controlling transmission enable and disable, a write data line (MOSI) 330 for the host to write data to the target device (e.g., an LCD display device), and a read data line (MISO) 340 for the host to read data. It does not include D / C communication lines.

[0052] Furthermore, such as Figure 4 As shown, in the three-wire 9-bit standard Serial Peripheral Interface (SPI) mode, each byte 410 requires 9 SCLK clock cycles. The first bit of each byte is a "type identifier bit (used to identify the content type)," and the last 8 bits of each byte are the transmitted content (command or data). In contrast, in the four-wire standard Serial Peripheral Interface (SPI) mode, each byte 420 requires 8 SCLK clock cycles. The 8 bits of each byte are the transmitted content (command or data), and its content type characteristics are represented by the level of a separate D / C communication line without occupying bits in the byte.

[0053] In one embodiment, the content type includes a command type; the step of reassembling the serial content to be transmitted into content conforming to the first serial format and compatible with the second serial format according to the content type to obtain the converted serial content includes:

[0054] The corresponding first content conversion logic is determined according to the command type; through the first content conversion logic, the serial content to be transmitted is reassembled into content that conforms to the first serial format and is compatible with the second serial format, thereby obtaining the converted serial content.

[0055] The first content conversion logic bit is a preset logic program used to reassemble command-type content. If the content type of the serial content to be transmitted is identified as a command type, the corresponding first content conversion logic can be used to reassemble the serial content to be transmitted. Through the first content conversion logic, the serial content to be transmitted can be reassembled into content that conforms to the first serial format and is compatible with the second serial format, resulting in the converted serial content.

[0056] In one embodiment, reassembling the serial content to be transmitted into content that conforms to the first serial format and is compatible with the second serial format to obtain the converted serial content may specifically include:

[0057] Create a command transmission array of a predetermined compatible byte size, wherein the number of bits in each byte of the command transmission array is the same as the number of bits in the first serial format; in each bit of the command transmission array, set the command identifier content and the content of the serial content to be transmitted according to the second serial format to obtain the converted serial content.

[0058] The predetermined compatible byte count is the number of bytes used for the content of the predetermined reassembly command type. The predetermined compatible byte count can be set according to the actual situation; for example, the predetermined compatible byte count can be 2. A command transmission array of the predetermined compatible byte count size is created. The number of bits in each byte of the command transmission array is the same as the number of bits in the byte corresponding to the first serial format. The serial content to be transmitted is in the first serial format. For example, if the first serial format is the serial format of the four-wire standard Serial Peripheral Interface (SPI), the predetermined compatible byte count can be set to 2, and a 2-byte command transmission array can be created. Each byte in the command transmission array is 8 bits (that is, the number of bits in each byte is the same as the number of bits in the byte corresponding to the first serial format, 8 bits).

[0059] By setting the command identifier content and the content of the serial content to be transmitted in each bit of the created command transmission array according to the second serial format, a converted serial content that conforms to the first serial format and is compatible with the second serial format can be obtained.

[0060] For example, a 2-byte command transmission array is created, where each byte is 8 bits. The second serial format is a 3-wire 9-bit standard Serial Peripheral Interface (SPI) format, where each byte is 9 bits. In this case, the first bit of the "first byte" of the command transmission array can be set to the command identifier (used to identify that the transmitted content is a command), and the next 7 bits can be used to store the first 7 bits of the serial content to be transmitted. The last bit of the serial content to be transmitted can be placed in the first bit of the "second byte" of the command transmission array. This results in a converted serial content that conforms to the first serial format and is compatible with the second serial format; that is, the last 7 bits of the "second byte" of the command transmission array are discarded. Therefore, when the target device supports the 3-wire 9-bit standard Serial Peripheral Interface (SPI) interface mode, it can successfully identify the converted serial content according to the 3-wire 9-bit standard.

[0061] In one embodiment, the content type includes a data type; the step of reassembling the serial content to be transmitted into content that conforms to the first serial format and is compatible with the second serial format according to the content type to obtain the converted serial content may include: determining a corresponding second content conversion logic according to the data type; and reassembling the serial content to be transmitted into content that conforms to the first serial format and is compatible with the second serial format through the second content conversion logic to obtain the converted serial content.

[0062] The second content conversion logic bit is a preset logic program for reconstructing data types. If the content type of the serial content to be transmitted is identified as a data type, the corresponding second content conversion logic can be used to reconstruct the serial content to be transmitted. Through the second content conversion logic, the serial content to be transmitted can be reconstructed into content that conforms to the first serial format and is compatible with the second serial format, resulting in the converted serial content.

[0063] In one embodiment, reassembling the serial content to be transmitted into content that conforms to the first serial format and is compatible with the second serial format to obtain the converted serial content may include: determining the corresponding number of data-compatible bytes based on the number of bytes in the serial content to be transmitted; creating a data transmission array of a size corresponding to the number of data-compatible bytes; and setting data identifier content and the content in the serial content to be transmitted in each bit of the data transmission array according to the second serial format to obtain the converted serial content.

[0064] When the serial content to be transmitted is data, its length is usually not fixed. In this case, the corresponding number of compatible bytes can be determined based on the number of bytes of the serial content to be transmitted. For example, if the number of bytes of the serial content to be transmitted is 8 bytes, if it is converted to the second serial format corresponding to the three-wire nine-bit standard serial peripheral interface, a data identifier (used to identify that the transmitted content is data) needs to be added before every 8 bits of data. Therefore, the number of compatible bytes can be 8 bytes + 1 = 9 bytes.

[0065] Furthermore, by setting the data identifier content and the content of the serial content to be transmitted in each bit of the created data transmission array according to the second serial format, a converted serial content that conforms to the first serial format and is compatible with the second serial format can be obtained.

[0066] For example, if the serial content to be transmitted is 2 bytes long with 8 bits per byte, a 3-byte data transmission array can be created, with each byte in the data transmission array being 8 bits. If the second serial format is the serial format of the three-wire 9-bit standard Serial Peripheral Interface (SPI), then each byte in the second serial format is 9 bits. In this case, the first bit of the "first byte" in the data transmission array can be set as the data identifier, and the next 7 bits can be used to store the first 7 bits of the first byte of the serial content to be transmitted. The last bit of the first byte of the serial content to be transmitted can be placed in the first bit of the "second byte" in the data transmission array. At the same time, the second bit of the "second byte" in the data transmission array can be set as the data identifier, and the next 6 bits can be used to store the first 6 bits of the second byte of the serial content to be transmitted. The last two bits of the second byte of the serial content to be transmitted can be placed in the first two bits of the "third byte" in the data transmission array. This results in a converted serial content that conforms to the first serial format and is compatible with the second serial format. In other words, the last 6 bits of the "third byte" in the data transmission array are discarded. Furthermore, when the target device is an interface mode that supports the three-wire 9-bit standard Serial Peripheral Interface (SPI), the converted serial content can be successfully identified from the converted serial content according to the three-wire 9-bit standard.

[0067] Furthermore, in one embodiment of the foregoing embodiments of this application, the first serial peripheral interface is a four-wire standard serial peripheral interface, and the second serial peripheral interface is a three-wire nine-bit standard serial peripheral interface. Based on the foregoing embodiments of this application, a target device that is compatible with the three-wire nine-bit standard can be effectively achieved, using a four-wire standard host. It is understood that in other embodiments, the first serial peripheral interface and the second serial peripheral interface can be two serial peripheral interfaces of different standards.
