Referring to fig. 3, fig. 3 is a schematic diagram of a detection circuit of a WiFi module provided in another embodiment of the present application, as shown in the figure, in an embodiment, the detection circuit of the WiFi module further includes:
a controller 200.
The controller 200 includes a signal transmitting terminal.
The signal transmitting end of the controller 200 is used for connecting the input end of the WiFi module.
The controller 200 sends a control signal to the input end of the WiFi module through a signal sending end, where the control signal is used to instruct each pin to be tested of the WiFi module to output a corresponding control level signal.
In practical application, a processor can be arranged in the WiFi module, and the processor arranged in the WiFi module controls the output level of the pin to be tested of the WiFi module; the external controller can also be used for controlling the output level of the pin to be tested of the WiFi module.

Fig. 4 is a schematic implementation flowchart of a detection method of a WiFi module provided in the embodiment of the present application, where the method is applied to a detection circuit of a WiFi module provided in the embodiments of fig. 1, fig. 2, and fig. 3. As shown, the method may comprise the steps of:
step S101, controlling all pins to be tested of the WiFi module to output first preset level signals through a signal sending end of the controller, and receiving initial feedback signals through a signal receiving end of the controller, wherein the initial feedback signals are feedback signals generated after the detection module in the detection circuit performs preset processing on the received first preset level signals.
Optionally, the preset processing is an exclusive or operation. The logical expression of the exclusive-or operation is:
F＝A⊕B＝AB’+A’B。
specifically, when a is 0 and B is 0, F is 0; when a is 0 and B is 1, F is 1; when A is 1 and B is 0, F is 1; when a is 1 and B is 1, F is 0.
In practical applications, the first predetermined level signal may be a high level signal or a low level signal. Assuming that the first preset level signal is a high level signal, the detection circuit has two exclusive or gate devices, and a first input end of the first exclusive or gate device is grounded (i.e. a low level signal is input); when a first pin to be tested of the WiFi module outputs a high level signal, namely the second input end of the first XOR gate device receives the high level signal, the output of the first XOR gate device is the high level signal according to the principle of XOR operation; the first input end of the second exclusive-or gate device is connected with the output signal of the first exclusive-or gate device, the second input end of the second exclusive-or gate device is connected with a second pin to be tested of the WiFi module (the second pin to be tested outputs a high level signal), namely, the first input end of the second exclusive-or gate device receives the high level signal, the second input end of the second exclusive-or gate device receives the high level signal, and the output of the second exclusive-or gate device is a low level signal according to the exclusive-or operation principle. The output of the second exclusive or gate is the initial feedback signal, so the initial feedback signal is a low level signal. The above is only an example of obtaining the initial feedback signal, and the number of the specific exclusive or gate devices is not limited specifically.
And step S102, taking any pin to be tested of the WiFi module as a target pin, and controlling the target pin to output a second preset level signal.
The second preset level signal is a signal different from the first preset level signal. If the first preset level signal is a high level signal, the second preset level signal is a low level signal; if the first preset level signal is a low level signal, the second preset level signal is a high level signal.
Step S103, receiving a test feedback signal through a signal receiving end of the controller, where the test feedback signal is a feedback signal generated after the detection module performs a preset process on the received second preset level signal of the target pin.
On the basis of the example in step S101, the obtained initial feedback signal is a low level signal, and assuming that the first pin to be tested of the WiFi module is taken as a target pin, the target pin outputs the low level signal, that is, the second input end of the first exclusive or gate receives the low level signal; the second input end of the first exclusive-OR gate is still grounded, and the output of the first exclusive-OR gate is a low level signal according to the original exclusive-OR operation; the first input end of the second exclusive-or gate receives the output signal of the first exclusive-or gate, namely the first input end of the second exclusive-or gate receives a low level signal; the second input end of the second exclusive-OR gate is connected with the second pin to be tested and still receives a high-level signal; according to the principle of exclusive-or operation, the output of the second exclusive-or gate is a high level signal, i.e. the test feedback signal is a high level signal.
Step S104, judging whether the test feedback signal is the same as the initial feedback signal.
Step S105, if the test feedback signal is different from the initial feedback signal, determining that the target pin is normal.
And step S106, if the test feedback signal is the same as the initial feedback signal, judging that the target pin has a fault.
Based on the examples in S101 and S103, when the first pin to be tested is taken as the target pin, the initial feedback signal is a low level signal, and the test feedback signal is a high level signal, that is, the test feedback signal is different from the initial feedback signal, the target pin is normal, that is, the first pin to be tested is normal. Because, if the first pin to be tested fails, the level signal cannot be output, that is, the output signal of the first pin to be tested does not affect the state of the final feedback signal, then the initial feedback signal is the same as the test feedback signal.
Referring to fig. 5, fig. 5 is a schematic flow chart illustrating an implementation of a detection method for a WiFi module according to another embodiment of the present disclosure, as shown in the drawing, in an embodiment, after determining whether the test feedback signal is the same as the initial feedback signal, the method further includes:
and judging whether a pin to be tested outputting a first preset level signal exists in the N pins to be tested of the WiFi module.
If a pin to be tested which outputs a first preset level signal exists in the N pins to be tested of the WiFi module, marking the pin to be tested as a target pin, and taking the test feedback signal as an initial feedback signal.
And controlling the target pin to output a second preset level signal through a signal sending end of the controller, and receiving a test feedback signal through a signal receiving end of the controller.
And judging whether the test feedback signal is the same as the initial feedback signal.
And if the test feedback signal is different from the initial feedback signal, judging that the target pin is normal.
And if the test feedback signal is the same as the initial feedback signal, judging that the target pin has a fault.
In practical application, the pins to be tested of the WiFi module can be tested according to a certain sequence, such as an arrangement sequence, a numbering sequence, and the like; and random testing can also be carried out, namely, one pin to be tested is randomly selected from the pins to be tested of the WiFi module to be used as a target pin, and the testing is carried out until all the pins to be tested of the WiFi module are tested.
In the testing process, after each pair of pins to be tested is tested, the test feedback signal obtained in the test is used as an initial feedback signal, that is, the feedback signal obtained in each test needs to be compared with the feedback signal obtained in the last test, so that whether the current pin to be tested is normal can be judged.
Optionally, before the controlling, by the signal sending end of the controller, all pins to be tested of the WiFi module to output a first preset level signal, the method further includes:
and numbering each pin to be tested of the WiFi module respectively.
Optionally, after determining whether there is a pin to be tested that outputs a first preset level signal in the N pins to be tested of the WiFi module, the method further includes:
and if the pins to be detected which output the first preset level signal do not exist in the N pins to be detected of the WiFi module, counting the number of the failed pins to be detected in the WiFi module and the serial number of the failed pins to be detected.
And generating a detection report according to the number of the failed pins to be detected and the serial number of the failed pins to be detected.
Specifically, suppose that there are 2 faulty pins to be tested, and the numbers of the faulty pins to be tested are 1 and 3; then the detection report is generated as that the pin 1 to be detected is in fault, the pin 2 to be detected is normal, and the pin 3 to be detected is in fault. The above is only an example, and the number of the pins to be detected and the form of the detection report are not specifically limited.
According to the embodiment of the application, the feedback signal is received from the output end of the detection module by controlling the level signal of the pin to be detected of the WiFi module, and whether the pin to be detected of the WiFi module breaks down or not is judged by judging the state of the feedback signal. By the method, the WiFi module can be automatically detected, manual detection is avoided, and the detection efficiency of the WiFi module is effectively improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
