[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.

[0053] Embodiment 1:

[0054] Figure 1 This is a flow chart of a method for testing the stability of a universal serial port driver provided in Embodiment 1 of the present invention.

[0055] Reference Figure 1 , the method comprises the following steps:

[0056] Step S101, obtaining test parameters input by a user;

[0057] Step S102, determining whether the number of test parameters is a set number;

[0058] Step S103, if yes, determine the serial port number, serial port parameters, mode type, character string and the number of cycles of sending and receiving according to the test parameters;

[0059] Here, if the number of test parameters is not the set number, the program will exit.

[0060] Step S104, when the mode type is the first mode, the first board sends the character string to the client, and the first board receives the first data sent by the client;

[0061] Step S105, when the mode type is the second mode, the first board is used as a receiving end, and the second board is used as a sending end;

[0062] Step S106, the receiving end accumulates and verifies the second data each time it receives the second data sent by the sending end;

[0063] Step S107, when the verification is successful, the receiving end replies to the sending end with the set mark data, and the sending end continues to send the set mark data after receiving the set mark data, until the number of transmissions reaches the cycle number and the cycle ends.

[0064] In this embodiment, a universal serial port driver stability test method is used to meet the self-test requirements, using a C language source program. When using this test method, different test modes can be started according to different input parameter combinations. This application mainly includes two self-test modes.

[0065] The first mode is that the first board is connected to the client via a standard serial port (such as RS232 / 485, etc.), the first board runs the test program, the client runs the serial port debugging software, the first board can send any string input according to the command line, and receive the first data sent by the client at the same time. The client can receive the string sent by the first board; at the same time, the client can edit any content to be sent and send it to the first board. Among them, the client can be a personal computer, a desktop computer or a laptop.

[0066] In the second mode, the first board and the second board are connected via a standard serial port (such as RS232 / 485, etc.), and the two boards can start the receiving and sending processes respectively according to different input parameters (R / W). The sending end sends 1024 times in a loop, sending 1 byte for the first time, 2 bytes for the second time, and so on, until the last time 1024 bytes are sent, thus realizing the communication flow change data with a granularity of 1 byte (Byte).

[0067] The receiving end accumulates and checks each time after receiving the second data. After the check is correct, it sends back the set mark data (0xa5a5a5a5). After receiving the set mark data, the sending end continues to send the next process until the number of transmissions reaches the number of cycles and the cycle ends. This fine-grained testing process can detect the integrity and stability of the serial port driver, and can promptly discover problems introduced during the transplantation and adaptation process, ensuring the delivery quality of the product.

[0068] The testing method of the present application is easy to implement, efficient and stable. When the platform is imported, it can timely detect possible problems in the transplantation and adaptation of the serial port driver to ensure the delivery quality.

[0069] Further, step S103 includes the following steps:

[0070] Step S201, obtaining the serial port number according to the first parameter of the test parameter;

[0071] Step S202, obtaining serial port parameters according to the second to fifth parameters of the test parameters; wherein the serial port parameters include baud rate, data bits (7 bits or 8 bits) and parity check (N represents no check or E represents even check or O represents odd check);

[0072] Step S203, according to the sixth parameter of the test parameter, obtaining the mode type as the first mode or the second mode;

[0073] Step S204, when the mode type is the first mode, obtaining a character string according to the seventh parameter of the test parameter;

[0074] Step S205, when the mode type is the second mode, the number of cycles is obtained according to the seventh parameter.

[0075] Here, if the mode type is the second mode, the sending buffer is initialized, and the size of the sending buffer is 1024 bytes; the content of the second data is 0 to 255; the elements starting from array subscript 256 are filled with 0, and so on;

[0076] Further, step S104 includes the following steps:

[0077] Step S301, determining whether the user inputs an end instruction;

[0078] Step S302: if not, clear the receiving buffer of the first board and send the character string to the serial communication software of the client so that the serial communication software can view the character string;

[0079] Step S303, the first board receives first data sent by the serial port communication software;

[0080] Step S304: if yes, then end.

[0081] Specifically, the present application adopts two test modes. The first mode is used for the first board to communicate with the serial communication software of the client. The first board can specify the string to be sent in the command line and receive the first data from the serial communication software at the same time.

[0082] The second mode uses two boards to communicate with each other, with the first board as the receiving end and the second board as the sending end. The first board receives (R) and the other board sends (W). The sending and receiving sides can pass in different parameters when starting the test case. The sending end sends 1024 times in a loop, with 1 byte sent for the first time, 2 bytes sent for the second time, and so on, until the last time 1024 bytes are sent, thus realizing the communication flow change data with a granularity of 1 byte.

[0083] The receiving end accumulates and verifies each time it receives data. After the verification is correct, it sends back the set mark data (0xa5a5a5a5). After receiving the set mark data, the sending end continues to send the next time until all cycles are completed.

[0084] Furthermore, the size of the sending buffer of the sending end is 1024 bytes, and the content of the second data is 0-255 bytes.

[0085] Furthermore, the method further comprises the following steps:

[0086] Step S401, opening the corresponding serial port according to the serial port number;

[0087] Step S402, configuring the serial port according to the serial port parameters.

[0088] Here, after the serial port is configured according to the obtained serial port parameters, the test process of the first mode or the second mode is started.

[0089] Furthermore, the first single board is connected to the client via a standard serial port, and the first single board is connected to the second single board via a standard serial port.

[0090] Embodiment 2:

[0091] Figure 2 This is a flow chart of the execution process of the first mode provided in the second embodiment of the present invention.

[0092] Reference Figure 2 , the method comprises the following steps:

[0093] Step S501, determine whether Ctrl+C is pressed to end; if yes, execute step S502; if not, execute step S503;

[0094] Step S502, end;

[0095] Step S503, the receiving buffer is cleared to 0;

[0096] Step S504, executing sending;

[0097] Step S505, executing receiving (blocking type).

[0098] Specifically, the execution process consists of a while(1) loop, and the exit condition is to press the Ctrl+C keys to end the test program; otherwise, the loop continues. When the loop comes in, the receiving buffer is cleared first, and the size of the receiving buffer is 1024 bytes; then the string is sent out; at the same time, the reception is started to receive the first data sent by the serial communication software of the client; the serial communication software can observe the string sent by the first single board, and at the same time, the first data to be sent can be input and sent to the first single board.

[0099] Example of commands for the first mode:

[0100] $. / uart-simple-test 0baud 8N 1A'helloworld1234'

[0101] The 0th parameter "uart-simple-test" indicates the name of the program;

[0102] The first parameter "0" indicates serial port number 0;

[0103] The second parameter "baud" indicates the baud rate, such as 115200;

[0104] The third parameter "8" indicates that the number of bits of data is 8;

[0105] The fourth parameter "N" means not to use parity check;

[0106] The fifth parameter "1" means the stop bit is 1;

[0107] The sixth parameter "A" indicates operation mode one;

[0108] The seventh parameter "helloworld1234" indicates the character string sent by the board.

[0109] Figure 3 This is a flow chart of the execution process of the second mode provided in the second embodiment of the present invention.

[0110] Reference Figure 3 , the method comprises the following steps:

[0111] Step S601, determining at the receiving end whether the number of cycles is full; if yes, then ending; if no, executing step S602;

[0112] Step S602, receiving second data sent by the sending end;

[0113] Step S603, perform accumulation and verification on the second data to determine whether the received verification is OK; if not, end; if yes, execute step S604;

[0114] Step S604, sending back setting mark data (0xa5a5a5a5);

[0115] Step S605, the loop variable body is incremented;

[0116] Step S606, the sending end determines whether the number of cycles is full; if yes, the process ends; if no, the process proceeds to step S607;

[0117] Step S607, sending second data to the receiving end;

[0118] Step S608, receiving setting mark data from the receiving end;

[0119] Step S609, determine whether the received marking data is OK; if yes, execute step S610; if no, end;

[0120] Step S610, the loop variable body is incremented.

[0121] Specifically, the receiving end and the sending end of the process are each composed of a for loop, and the number of loops is 1024. When the program starts, the program of the receiving end is started first (parameter 6 is set to R), and then the program of the sending end is started (parameter 6 is set to W).

[0122] After the receiving end starts receiving, it waits for receiving. After the sending end starts sending, it immediately sends the first byte, and the content of the byte is 0x00. The receiving end receives 0x00 sent by the sending end. After the verification is correct (the verification method is to accumulate the received content by byte), the setting mark data (0xa5a5a5a5) is sent back. After receiving the setting mark data, the sending end starts the second transmission and sends 2 bytes. The content of the bytes is 0x00 and 0x01. The receiving end receives 0x00 and 0x01 sent by the sending end. After the verification is correct, the setting mark data (0xa5a5a5a5) is sent back. After receiving the setting mark data, the sending end starts the third transmission, and so on, until all cycles are completed. The logic of sending data at the sending end is summarized as follows:

[0123] The first time, send 1 byte 0;

[0124] The second time, send 2 bytes 0,1;

[0125] The third time, send 3 bytes 0, 1, 2;

[0126] The fourth time, 4 bytes 0, 1, 2, 3 are sent; ......

[0128] The 256th time, 256 bytes are sent 0, 1, 2, 3...255

[0129] The 257th time, 257 bytes are sent 0, 1, 2, 3... 255, 0 ......

[0131] The 1024th time, 1024 bytes are sent 0,1,2,......255,0,......255,0,......255,0,......255

[0132] Example of commands for the second mode:

[0133] $. / uart-simple-test 0baud 8N 1R 1024#Start the receiving board first

[0134] $. / uart-simple-test 0baud 8N 1W 1024#Restart the sending board

[0135] The 0th parameter "uart-simple-test" indicates the name of the program;

[0136] The first parameter "0" indicates serial port number 0;

[0137] The second parameter "baud" indicates the baud rate, such as 115200;

[0138] The third parameter "8" indicates that the number of bits of data is 8;

[0139] The fourth parameter "N" means not to use parity check;

[0140] The fifth parameter "1" means the stop bit is 1;

[0141] The sixth parameter "R or W" indicates running in the second mode;

[0142] The seventh parameter "1024" indicates the number of cycles of receiving or sending;
