[0064] Figure 1 The flowchart of a method for expanding the UART application based on the MTK platform of the present invention is shown.

[0065] As Figure 1 shown, in a first aspect of the present invention, a method for expanding the UART application based on the MTK platform is disclosed, and the method includes:

[0066] S102, obtaining first level information;

[0067] S104, determining whether the first level information is a preset level threshold;

[0068] S106, if so, determine the first number information according to the first level information;

[0069] S108, send a first handshake command according to the first number information;

[0070] S110, determine whether a first handshake feedback command is received;

[0071] S112, if so, determine the first peripheral device coding information according to the first handshake feedback command;

[0072] S114, set the UART communication configuration according to the first number information and the first peripheral device coding information.

[0073] It should be noted that the first level information is the interface level value used to detect the insertion of a peripheral device, including at least two level states, namely high level and low level; usually, a switching circuit or the like is used. When a peripheral device is connected, the output level of the switching circuit changes. The first number information is the number of the UART interface, which is used to configure the UART interface of the MTK platform. The first handshake command is a command for establishing a communication connection set according to the communication protocol of the preset peripheral device; the first handshake feedback command is a communication command fed back by the peripheral device to the MTK platform according to the correct first handshake command. The first peripheral device coding information is the coding set according to the peripheral device. For example, the coding of the Beidou positioning module is 0x01, and the coding of the RFID module is 0x02.

[0074] In this embodiment, if the first level information switches to a preset level threshold, indicating that a new peripheral device has been connected to the set UART interface, the number of the UART interface of the connected peripheral device is determined according to the first level information to obtain the first number information. A first handshake command is sent to the peripheral device through the UART interface pointed to by the first number information. If a communication command feedback by the peripheral device, that is, the first feedback command, is received, it means that a connection has been established between the UART interface pointed to by the first number information and the peripheral device; and the coding of the peripheral device is determined according to the first feedback command. Finally, the communication protocol is determined according to the coding of the peripheral device, and then the communication configuration parameters of the corresponding UART interface are set according to the first number information.

[0075] Figure 2 The flowchart of receiving the first handshake feedback command provided by the embodiment of the present invention is shown.

[0076] According to the embodiment of the present invention, as Figure 2 shown, the determination of whether the first handshake feedback command is received is specifically:

[0077] S202, sequentially obtain and send the first handshake command according to the preset handshake command library;

[0078] S204, within a preset first time period, determine whether a feedback instruction message is received;

[0079] S206, if so, then the feedback instruction message is a first handshake feedback instruction;

[0080] S208, if not, then update the first timeout count information;

[0081] S210, according to the first timeout count information, determine whether to send the handshake instruction again;

[0082] S212, if not, then the first handshake feedback instruction is not received.

[0083] It should be noted that, in this embodiment, the handshake instructions are sequentially sent according to the handshake instruction library, and by determining whether a feedback instruction message is received within a preset first time period, it is used to determine whether the first handshake feedback instruction is received. First, according to the preset handshake instruction library, the first handshake instruction is sequentially obtained and sent to the peripheral device; if a feedback instruction message returned by the peripheral device is received within the preset first time period, it indicates that the handshake with the peripheral device is successful, that is, the communication is established successfully, and the feedback instruction message of the peripheral device is the first handshake feedback instruction; if a feedback instruction message is not received within the preset first time period, it indicates that the handshake fails, and the first timeout count information of the current first handshake instruction is updated. Finally, according to the first timeout count information, determine whether to send the handshake instruction again. If not, it indicates that the handshake with the peripheral device fails and the communication connection cannot be established, that is, it is determined that the first handshake feedback instruction is not received.

[0084] According to the embodiment of the present invention, the determining whether to send the first handshake instruction again according to the first timeout count information is specifically:

[0085] Determine whether the first timeout count information is lower than a preset count threshold;

[0086] If so, resend the first handshake instruction;

[0087] If not, then determine whether the first handshake instruction is the last handshake instruction in the handshake instruction library;

[0088] If so, stop sending the handshake instruction;

[0089] If not, then according to the preset handshake instruction library, sequentially obtain and send the first handshake instruction.

[0090] It should be noted that in this embodiment, the handshake command in the handshake command library is switched according to the first timeout count information. When the first timeout count information is lower than the preset count threshold, the current first handshake command is resent. When the first timeout count information is not lower than the preset count threshold, the handshake command is switched from the handshake command library. When a handshake command switch is required, it is determined whether the current first handshake command is the last handshake command in the handshake command library; if so, it means that all handshake commands cannot successfully handshake with the peripheral device, and the handshake command sending is stopped; if not, the next handshake command in the handshake command library is selected and set as the first handshake command.

[0091] Figure 3 The flowchart shows the confirmation of the first peripheral device coding information provided by the embodiment of the present invention.

[0092] According to the embodiment of the present invention, as Figure 3 shown, determining the first peripheral device coding information according to the first handshake feedback command specifically includes:

[0093] S302, obtaining communication protocol information according to the first handshake feedback command;

[0094] S304, analyzing the frame header information, frame tail information and check information of the communication protocol information to determine the peripheral communication device;

[0095] S306, obtaining the first peripheral device coding information according to the peripheral communication device.

[0096] It should be noted that in this embodiment, the coding of the peripheral communication device is confirmed by analyzing the communication protocol in the handshake feedback command. First, communication protocol information is obtained according to the first handshake feedback command, including but not limited to the frame header, frame tail, check mode, etc. in the communication data frame. Then, according to the communication protocol information, the type of the peripheral device is determined by querying the communication protocols in the stored peripheral device list, so as to determine the coding of the peripheral device.

[0097] According to the embodiment of the present invention, it further includes:

[0098] The peripheral communication device at least includes a Beidou positioning module and an RFID module.

[0099] It should be noted that in this embodiment, the peripheral communication devices that need to be connected to the MTK platform at least include a Beidou positioning module and an RFID module. The Beidou positioning module refers to an electronic module integrated with Beidou satellite navigation system positioning technology. It can receive signals sent by Beidou satellites, calculate information such as the precise position, speed, and time of the receiver through internal processing algorithms, and then communicate with the MTK platform through the UART interface. The RFID module, that is, the radio frequency identification module, is a wireless electronic tag system. It can identify the tags on items through electromagnetic fields and then communicate with the MTK platform through the UART interface.

[0100] According to an embodiment of the present invention, it further includes:

[0101] Convert the SPI interface to a UART interface through the conversion chip CH432T.

[0102] It should be noted that as an implementation method, the UART interface of the MTK platform is expanded through the conversion chip. CH432T is a UART interface conversion chip. It can convert interfaces such as USB interfaces and SPI interfaces into independent UART interfaces to provide additional communication channels in the case of limited serial port resources.

[0103] It is worth mentioning that it further includes:

[0104] Obtain the first peripheral device coding information;

[0105] Judge whether the first peripheral device coding information is a preset peripheral device coding;

[0106] If so, judge whether the coding of the peripheral device in the UART communication connection state is the same as the first peripheral device coding information;

[0107] If so, generate an installation exception instruction according to the first peripheral device coding information.

[0108] It should be noted that in this embodiment, by automatically identifying peripheral devices, it is used to judge whether there are abnormal situations such as repeated installation of peripheral devices. In practical applications, only one of individual communication modules is used on the same MTK platform. For example, only one Beidou positioning module is installed. In this embodiment, after detecting a newly connected peripheral device, according to the first peripheral device coding information of the newly connected peripheral device and the coding of the peripheral device connected to the configured UART interface, it is judged whether there is a situation of repeated installation of the preset peripheral device. If so, an installation exception instruction is generated according to the first peripheral device coding information, which is used to indicate that the installation of the peripheral device corresponding to the first peripheral device coding information is abnormal.

[0109] It is worth mentioning that it further includes:

[0110] Obtain communication protocol information according to the first handshake feedback instruction;

[0111] Send a first verification instruction according to the communication protocol information in combination with preset verification data;

[0112] Obtain a first verification feedback instruction;

[0113] Adjust the UART communication configuration according to the first feedback instruction.

[0114] It should be noted that in this embodiment, after the handshake of the peripheral device is successful, a secondary verification will be performed to ensure the accuracy of device communication. First, obtain communication protocol information according to the first handshake feedback instruction. Then, send a first verification instruction in combination with preset verification data. If the first verification feedback instruction is received normally, the UART communication configuration will not be adjusted. If the first verification feedback instruction is received abnormally, the connection between the peripheral device and the MTK platform will be disconnected by adjusting the UART communication configuration, and the device identification and verification will be performed again.

[0115] Figure 4 The block diagram of a UART expansion application system based on the MTK platform according to the present invention is shown.

[0116] As Figure 4 shown, in the second aspect of the present invention, a UART expansion application system 4 based on the MTK platform is disclosed, including a memory 41 and a processor 42. The memory includes a UART expansion application method program based on the MTK platform. When the UART expansion application method program based on the MTK platform is executed by the processor, the following steps are implemented:

[0117] Obtain first level information;

[0118] Judge whether the first level information is a preset level threshold;

[0119] If so, determine first number information according to the first level information;

[0120] Send a first handshake instruction according to the first number information;

[0121] Judge whether a first handshake feedback instruction is received;

[0122] If so, determine first peripheral coding information according to the first handshake feedback instruction;

[0123] Set the UART communication configuration according to the first number information and the first peripheral coding information.

[0124] It should be noted that the first level information is the interface level value used to detect the insertion of a peripheral device, including at least two level states, namely high level and low level; usually, a switching circuit or the like is used, and when the peripheral device is connected, the output level of the switching circuit changes. The first number information is the number of the UART interface, which is used to configure the UART interface of the MTK platform. The first handshake command is a command for establishing a communication connection set according to the communication protocol of the preset peripheral device; the first handshake feedback command is a communication command fed back by the peripheral device to the MTK platform according to the correct first handshake command. The first peripheral coding information is the coding set according to the peripheral device. For example, the coding of the Beidou positioning module is 0x01, and the coding of the RFID module is 0x02.

[0125] In this embodiment, if the first level information switches to a preset level threshold, indicating that a new peripheral device has been connected to the set UART interface, the number of the UART interface to which the peripheral device is connected is determined according to the first level information to obtain the first number information. The first handshake command is sent to the peripheral device through the UART interface pointed to by the first number information. If a communication command fed back by the peripheral device, that is, the first feedback command, is received, it means that a connection has been established between the UART interface pointed to by the first number information and the peripheral device; and the coding of the peripheral device is determined according to the first feedback command. Finally, the communication protocol is determined according to the coding of the peripheral device, and the communication configuration parameters of the corresponding UART interface are set according to the first number information.

[0126] According to the embodiment of the present invention, the judgment of whether the first handshake feedback command is received is specifically as follows:

[0127] According to the preset handshake command library, the first handshake commands are sequentially obtained and sent;

[0128] Within a preset first time, it is judged whether feedback command information is received;

[0129] If so, the feedback command information is the first handshake feedback command;

[0130] If not, the first timeout count information is updated;

[0131] According to the first timeout count information, it is judged whether to send the handshake command again;

[0132] If not, the first handshake feedback command is not received.

[0133] It should be noted that in this embodiment, the handshake commands are sequentially sent according to the handshake command library, and by determining whether the feedback command information is received within a preset first time, it is used to determine whether the first handshake feedback command is received. First, according to the preset handshake command library, the first handshake command is sequentially obtained and sent to the peripheral device; if the feedback command information returned by the peripheral device is received within the preset first time, it means that the handshake with the peripheral device is successful, that is, the communication is successfully established, and the feedback command information of the peripheral device is the first handshake feedback command; if the feedback command information is not received within the preset first time, it means that the handshake fails, and the first timeout count information of the current first handshake command is updated. Finally, according to the first timeout count information, it is judged whether it is necessary to send the handshake command again. If not, it means that the handshake with the peripheral device fails and the communication connection cannot be established, that is, it is determined that the first handshake feedback command is not received.

[0134] According to an embodiment of the present invention, the determining whether to send the first handshake command again according to the first timeout count information is specifically:

[0135] Judge whether the first timeout count information is lower than a preset count threshold;

[0136] If so, resend the first handshake command;

[0137] If not, then judge whether the first handshake command is the last handshake command in the handshake command library;

[0138] If so, stop sending the handshake command;

[0139] If not, then according to the preset handshake command library, the first handshake command is sequentially obtained and sent.

[0140] It should be noted that in this embodiment, the handshake commands in the handshake command library are switched according to the first timeout count information. When the first timeout count information is lower than the preset count threshold, the current first handshake command is resent. When the first timeout count information is not lower than the preset count threshold, the handshake command is switched from the handshake command library. When the handshake command needs to be switched, it is judged whether the current first handshake command is the last handshake command in the handshake command library; if so, it means that all handshake commands cannot handshake successfully with the peripheral device, and the handshake command is stopped from being sent; if not, the next handshake command in the handshake command library is selected and set as the first handshake command.

[0141] According to an embodiment of the present invention, the determining the first peripheral coding information according to the first handshake feedback command is specifically:

[0142] Obtain the communication protocol information according to the first handshake feedback command;

[0143] Analyze the frame header information, frame tail information, and check information of the communication protocol information to determine the peripheral communication device;

[0144] Obtain the first peripheral coding information according to the peripheral communication device.

[0145] It should be noted that in this embodiment, by analyzing the communication protocol in the handshake feedback instruction, the coding of the peripheral communication device is confirmed. First, according to the first handshake feedback instruction, obtain the communication protocol information, which includes but is not limited to the frame header, frame tail, check mode, etc. in the communication data frame. Then, according to the communication protocol information, determine the type of the peripheral device by querying the communication protocols in the stored peripheral device list, so as to determine the coding of the peripheral device.

[0146] According to an embodiment of the present invention, it further includes:

[0147] The peripheral communication device at least includes a Beidou positioning module and an RFID module.

[0148] It should be noted that in this embodiment, the peripheral communication devices that need to be connected to the MTK platform at least include a Beidou positioning module and an RFID module. The Beidou positioning module refers to an electronic module integrated with Beidou satellite navigation system positioning technology. It can receive the signals sent by Beidou satellites, calculate the accurate position, speed, time, etc. of the receiver through the internal processing algorithm, and then communicate with the MTK platform through the UART interface. The RFID module, that is, the radio frequency identification module, is a wireless electronic tag system. It can identify the tags on items through the electromagnetic field and then communicate with the MTK platform through the UART interface.

[0149] According to an embodiment of the present invention, it further includes:

[0150] Convert the SPI interface to a UART interface through the conversion chip CH432T.

[0151] It should be noted that as an implementation method, the UART interface of the MTK platform is expanded through the conversion chip. CH432T is a UART interface conversion chip. It can convert interfaces such as USB interfaces and SPI interfaces into independent UART interfaces to provide additional communication channels in the case of limited serial port resources.

[0152] It is worth mentioning that it further includes:

[0153] Obtain the first peripheral coding information;

[0154] Judge whether the first peripheral coding information is a preset peripheral coding;

[0155] If so, judge whether the coding of the peripheral in the UART communication connection state is the same as the first peripheral coding information;

[0156] If so, an installation exception instruction is generated according to the first peripheral coding information.

[0157] It should be noted that in this embodiment, by automatically identifying peripheral devices, it is used to determine whether there are abnormal situations such as repeated installation of peripheral devices. In actual applications, only one individual communication module will be used on the same MTK platform. For example, only one Beidou positioning module is installed. In this embodiment, after detecting a newly connected peripheral device, according to the first peripheral coding information of the newly connected peripheral device and the coding of the peripheral device connected to the configured UART interface, it is determined whether there is a situation of repeated installation of the set peripheral device. If so, an installation exception instruction is generated according to the first peripheral coding information, which is used to indicate that the peripheral device corresponding to the first peripheral coding information is installed abnormally.

[0158] It is worth mentioning that it further includes:

[0160] According to the communication protocol information, combined with preset verification data, send a first verification instruction;

[0161] Obtain a first verification feedback instruction;

[0162] Adjust the UART communication configuration according to the first feedback instruction.

[0163] It should be noted that in this embodiment, after the handshake of the peripheral device is successful, a secondary verification will be performed to ensure the accuracy of device communication. First, obtain communication protocol information according to the first handshake feedback instruction. Then, combined with preset verification data, send a first verification instruction. If the first verification feedback instruction is received normally, the UART communication configuration is not adjusted. If the first verification feedback instruction is received abnormally, the connection between the peripheral device and the MTK platform is disconnected by adjusting the UART communication configuration, and the device identification and verification are performed again.

[0164] The third aspect of the present invention provides a computer-readable storage medium, which includes a UART expansion application method program based on the MTK platform. When the UART expansion application method program based on the MTK platform is executed by a processor, the steps of the UART expansion application method based on the MTK platform as described in any one of the above are realized.

[0165] In summary, the present invention provides a method, system, and storage medium for expanding the application of UART based on the MTK platform. First, it is determined whether there is a peripheral device connected according to the first level information; when there is a peripheral device connected, the first number information of the connected UART interface is obtained, and then the first handshake command is sent according to the first number information; then, if the first handshake feedback command is received, the first peripheral coding information is determined according to the first handshake feedback command; finally, according to the first number information and the first peripheral coding information, the UART communication configuration of the MTK platform is configured to establish a communication connection with the peripheral device; by automatically identifying and configuring the UART interface, while increasing the number of UART peripherals connected to the MTK platform, the problem of unable to communicate due to the peripheral device being connected to the wrong channel is avoided, and the fault tolerance rate of production work is improved.
