When the communication module B sends a high level signal to the receiving port RX1 of the communication module a through the sending port TX2, the voltage of the receiving port RX1 of the communication module a is pulled high by the power supply VCC through the first resistor R1, and the receiving port RX1 of the communication module a receives the high level signal, thereby completing the communication between the communication module a and the communication module B.
The above procedure is that when the transmission port TX1 of the communication module a is connected to the reception port RX2 of the communication module B, and the transmission port TX2 of the communication module B is connected to the reception port RX1 of the communication module a, the communication module a and the communication module B communicate normally. However, in the actual product design process, due to the change of circuit design requirements or the replacement of design schemes, the definitions of the communication ports of the communication module a and the communication module B may be changed, so that the port connections are no longer matched, and the communication module a and the communication module B cannot communicate normally.
Based on this, embodiments of the present application provide a communication port matching method, apparatus, communication module, and storage medium, which can determine whether a port connection relationship between two communication modules is matched, and in case of no match, modify a port definition to match the port connection relationship, thereby ensuring normal communication between the two communication modules.

It should be noted that the following process with the communication module a as the execution subject may also be completed with the communication module B as the execution subject, which is not limited in the embodiment of the present application.
Referring to fig. 2, a schematic flow chart of a communication port matching method according to an embodiment of the present invention is shown, and as shown in fig. 2, the method includes:
s20: and acquiring the data receiving state of the preset receiving port.
In this embodiment, taking the port communication system shown in fig. 1 as an example, two communication ports of a communication module a are communicatively connected with two communication ports of a communication module B, after the communication module a and the communication module B are powered on and initialized, the two communication ports of the communication module a are defined in advance by a Micro Control Unit (MCU) of the communication module a, it is determined that one communication port of the communication module a is a preset receiving port, the other communication port of the communication module a is a preset transmitting port, the two communication ports of the communication module B are defined in advance by a MCU of the communication module B, it is determined that one communication port of the communication module B is a receiving port, and the other communication port of the communication module B is a transmitting port.

The port connection relation mismatch is that a preset receiving port of the communication module A is connected with a receiving port of the communication module B, and a preset sending port of the communication module A is connected with a sending port of the communication module B; correspondingly, the port connection relationship is matched in that a preset receiving port of the communication module a is connected with a sending port of the communication module B, and a preset sending port of the communication module a is connected with an interface port of the communication module B.
In an optional embodiment, the determining whether the port connection relationship between the two communication modules matches according to the data receiving status in S30 may include:
if the data receiving state is: and in a preset period, presetting that the receiving port does not receive data, and determining that the port connection relation is not matched.
In this embodiment, the data receiving rule may be a rule that the preset receiving port receives data in a preset period, and if the data receiving state does not satisfy the preset receiving rule, that is, the preset receiving port of the communication module a does not receive the data sent by the sending port of the communication module B in the preset period, it is determined that the port connection relationship between the communication module a and the communication module B is not matched.
For example, as shown in fig. 1, when the communication module B sends a signal to the communication module a through the sending port, if the port connection relationships of the communication module a and the communication module B are matched, the voltage of the preset receiving port of the communication module a is pulled high by the power VCC through the first resistor R1, the preset receiving port of the communication module a receives a high-level signal, and the communication module a and the communication module B can normally communicate; and if the preset receiving port of the communication module A does not receive the high-level signal in the preset period, determining that the port connection relation between the communication module A and the communication module B is not matched.

In this embodiment, when it is determined that the port connection relationship is not matched, the port connection relationship between the communication module a and the communication module B needs to be modified again, so that the preset receiving port of the communication module a is connected to the sending port of the communication module B, and the preset sending port of the communication module a is connected to the receiving port of the communication module B. Specifically, the manner of modifying the port connection relationship between the communication module a and the communication module B may be: and modifying the port definition of the communication module A to change the preset receiving port into a sending port for sending data and change the preset sending port into a receiving port for receiving data.
After port definitions of a preset receiving port and a preset sending port are modified, data are sent to the communication module A again through the sending port of the communication module B, a micro control unit in the communication module A detects the modified receiving port to obtain a data receiving state of the modified receiving port, whether the data receiving state meets a preset receiving rule or not is judged, if the data receiving state meets the preset receiving rule, port connection relations of the communication module A and the communication module B are determined to be matched, and normal communication can be achieved between the communication module A and the communication module B; if the data receiving state does not meet the preset receiving rule, the port connection relation between the communication module A and the communication module B is modified, so that the condition of port connection relation error is eliminated, and the communication fault between the ports of the communication module A and the communication module B is determined.
In the communication port matching method provided in the above embodiment, whether the port connection relationship between the two communication modules is matched is determined according to the data receiving state of the preset receiving port, and under the condition that the port connection relationship is not matched, the port definitions of the preset receiving port and the preset sending port are modified, the preset receiving port is changed into the sending port, the preset sending port is changed into the receiving port, so that the port connection relationship between the two communication modules is matched, and normal communication between the two communication modules is ensured.
On the basis of the above embodiments, the embodiments of the present application further provide another communication port matching method. Referring to fig. 3, a schematic flow chart of another communication port matching method according to an embodiment of the present application is shown in fig. 3, where before the step S20 obtains a data receiving status of a preset receiving port, the method may further include:
s11: a first port definition instruction for any communication module is received.
In this embodiment, the communication port of the communication module has a self-defined function, and a developer may send a first port definition instruction to the micro control unit of the communication module, where the first port definition instruction is used to define one port of the communication module as a receiving port and define another port of the communication module as a sending port.
S12: and configuring the first port as a preset receiving port and the second port as a preset sending port according to the first port definition instruction.
In this embodiment, the micro control unit configures the first port as a preset receiving port and configures the second port as a preset sending port according to the definition instructions of the two ports of the communication module in the received first port definition instructions, so that the first port is used for receiving data and the second port is used for sending data.
Further, after the port definitions of the communication module a and the communication module B are completed by using the above S11 to S12, the micro control unit of the communication module a or the micro control unit of the communication module a executes the above processes of S20 to S40, so as to match the communication ports between the communication module a and the communication module B.
According to the communication port matching method provided by the embodiment, the first port and the second port of the communication module are defined through the first port definition instruction, and the ports can be customized through the instruction, so that flexible setting of data receiving and data sending of the ports is realized, and the flexibility of circuit design is improved.
On the basis of the above embodiments, the embodiments of the present application further provide another communication port matching method. Referring to fig. 4, a schematic flow chart of another communication port matching method according to an embodiment of the present invention is shown in fig. 4, where as shown in fig. 4, if the port connection relationships are not matched in S40, modifying the port definitions of the preset receiving port and the preset sending port so that the preset receiving port becomes a sending port and the preset sending port becomes a receiving port, may include:
s41: and if the port connection relations are not matched, outputting first prompt information to indicate that the port connection relations are not matched.
In this embodiment, if the micro control unit of the communication module a determines that the port connection relationships of the communication module a and the communication module B are not matched according to the data receiving state, the micro control unit of the communication module a outputs first prompt information, where the first prompt information is used to indicate that the port connection relationships of the communication module a and the communication module B are not matched.
For example, the way for the micro control unit of the communication module a to output the first prompt information may be: a communication fault display unit is arranged on the communication module A, and the first prompt message can be a prompt message for controlling the communication fault display unit to emit light in a first light emitting mode by the micro control unit; the mode of the micro control unit of the communication module a outputting the first prompt information may also be: the micro control unit of the communication module A is connected with the computer device to output a first communication fault code to the computer device, wherein the first communication fault code is used for indicating that the port connection relation of the communication module A and the communication module B is not matched.
S42: a second port definition instruction for any of the communication modules is received.
In this embodiment, the second port definition instruction is used to modify the definitions of two ports of the communication module, modify the first port from a preset receiving port to a sending port, and modify the second port from a preset sending port to a receiving port. For example, the method for obtaining the second port definition instruction may be: after receiving the first prompt message, the research and development personnel send a second port definition instruction to a micro control unit of the communication module; the method can also comprise the following steps: the micro control unit of the communication module a directly triggers and generates the second port definition instruction based on the first prompt information, which is not limited in this application.
S43: and modifying the port definitions of the preset receiving port and the preset sending port according to the second port definition instruction, so that the preset receiving port is changed into a sending port, and the preset sending port is changed into a receiving port.
In this embodiment, according to the received definition instruction of the second port definition instruction on the two ports of the communication module, the micro control unit of the communication module modifies the first port from the preset receiving port to the sending port, and modifies the second port from the preset sending port to the receiving port.
It should be noted that the first port definition instruction needs to be sent to the communication module a and the communication module B to define both the two communication ports of the communication module a and the two communication ports of the communication module B, but when modifying the port definition according to the second port definition instruction, only the second port definition instruction needs to be sent to the communication module a or the communication module B, and only the port definition of one of the communication modules is modified. For example, because the mismatch of the port connection relationship means that the preset sending port of the communication module a is connected with the sending port of the communication module B, and the preset receiving port of the communication module a is connected with the receiving port of the communication module B, a developer may select to send the second port definition instruction to the micro control unit of the communication module a, or send the second port definition instruction to the micro control unit of the communication module B, but may not send the second port definition instruction to both the micro control unit of the communication module a and the micro control unit of the communication module B.
In the communication port matching method provided in the above embodiment, the port definitions of the first port and the second port of the communication module are modified through the second port definition instruction, so that it is ensured that when the port connection relationships are not matched, the port connection manner can be directly modified through the port definition instruction without manually modifying the connection relationship between the first port and the second port, on one hand, the efficiency of modifying the port connection manner is improved, on the other hand, the plugging/unplugging times of the first port and the second port are reduced, and the service life of the port is prolonged.
On the basis of the above embodiments, the embodiments of the present application further provide another communication port matching method. Referring to fig. 5, a schematic flow chart of another communication port matching method according to an embodiment of the present invention is shown in fig. 5, where as shown in fig. 5, if the port connection relationships are not matched in the above step S41, outputting the first prompt information may include:
s411: if the port connection relations are not matched, whether the port definition of any communication module is modified or not is judged.
In this embodiment, if the micro control unit of the communication module a determines that the port connection relationships of the communication module a and the communication module B are not matched according to the data receiving state, before outputting the first prompt information so that the research and development staff inputs the second port definition instruction according to the first prompt information, it is necessary to determine whether the port definition of the communication module a has been modified, that is, determine whether the first port definition instruction is an instruction for modifying the port definition of the communication module a.
In an optional embodiment, if the port connection relationship is not matched in the step S411, the determining whether the port definition of any communication module has been modified may include:
if the port connection relation is not matched, whether the port definition of any communication module is modified or not is judged according to the port interchange identification.
In this embodiment, the port interchange identifier is used to indicate whether the port definition of the communication module has been modified, where the port interchange identifier is a first preset value and is used to indicate that the port definition of the communication module has not been modified; and if the port interchange identifier is a second preset value, the port interchange identifier is used for indicating that the port definition of the communication module is modified. Illustratively, the first preset is 0 and the second preset is 1.
In the case that the port connection relationship is determined not to match, the micro control unit of the communication module a may determine whether the port definition of the communication module a has been modified according to the port interchange identifier. Specifically, the initial value of the port interchange identifier is a first preset value, and if the micro control unit of the communication module a receives a port definition instruction for the first time, that is, the first port definition instruction, the port interchange identifier maintains the first preset value; when the micro control unit of the communication module a receives the port definition instruction for the second time, that is, the second port definition instruction, the port interchange identifier is switched from the first preset to the first preset.
S412: and if the first prompt message is not modified, outputting the first prompt message.
In this embodiment, if the port interchange identifier is the first preset, and indicates that the port definition of the communication module a is not modified, the first prompt information is output, so that a developer sends a second port definition instruction to the micro control unit of the communication module a based on the first prompt information to modify the port definition of the communication module a, and the port interchange identifier is switched from the first preset to the second preset.
In an alternative embodiment, the method further comprises:
and if the communication module is modified, outputting second prompt information to indicate that port communication abnormity exists between the two communication modules.
In this embodiment, if the port interchange identifier is the second preset, and indicates that the port definition of the communication module a has been modified, the second prompt information is output, so that a developer determines that the port communication abnormality exists between the communication module a and the communication module B based on the second prompt information.
For example, the way for the micro control unit of the communication module a to output the second prompt message may be: the micro control unit of the communication module A controls the communication fault display unit to emit light in a second light emitting mode to give prompt information; the way for the micro control unit of the communication module a to output the second prompt information may also be: the micro control unit of the communication module A is connected with the computer equipment so as to output a second communication fault code to the computer equipment, and the second communication fault code is used for indicating that the port communication of the communication module A and the port communication of the communication module B are abnormal.
In the communication port matching method provided in the foregoing embodiment, when the port connection relationship is not matched, it is determined whether the port definition of the communication module has been modified, and if not, the first prompt message is sent to receive the second port definition instruction based on the first prompt message, and if so, the second prompt message is sent to indicate that there is port communication abnormality between the two communication modules, so as to avoid time waste in continuously sending the second state modification instruction when the port connection relationship is determined to be not matched, and improve the efficiency of testing whether the communication port connection relationship is matched.
