[0038] Please refer to Figure 1 , Figure 1The utility model provides a system architecture diagram of debugging circuit based on type C interface provides in the embodiment, and the debugging circuit based on type C interface is used to debug one or more chips on electronic hardware product single board 10. The debugging circuit based on type C interface mainly comprises two modules of debugging interface module 100 and communication interface convergence module 110 connected with debugging interface module 100. Among them, debugging interface module 100 includes interface subconnection module 101 and first type C socket module 102;Communication interface convergence module 110 contains second type C socket module 111, anti-reverse insertion detection module 112 and build connection prompting module 113.
[0039] In other embodiments, the communication interface convergence module 110 can be integrated on the electronic hardware product single board, which can be any electronic hardware device, such as a mobile phone, a tablet computer, a camera, and other household electronic hardware products, modules, or development boards in the development and debugging stage. The chips used in the electronic hardware product single board are not limited to central processing units (CPU), graphics processing units (GPU), microcontroller units (MCU), field programmable gate arrays (FPGA), and other types of processor chips.
[0040] The chips on the electronic hardware product single board are connected to the second Type-C socket module 111 through the communication interface, which is not limited to serial ports, inter-integrated circuit (IIC) interfaces, Ethernet interfaces, and other types of interfaces, and can be combined and converged in different numbers and different types.
[0041] In this embodiment, the interface subconnection module 101 is connected to the first Type-C socket module 102, and the interface subconnection module 101 is used to split the multiple interface signals obtained by the first Type-C socket module 102. The interface subconnection module 101 includes different pitch pins and / or sockets and / or flexible flat cable sockets, which are responsible for re-splitting, classifying, and organizing various communication interfaces converged on the pins of the first Type-C socket module 102, and arranging them into connection interfaces that can be externally connected for debugging. The externally connected debugging connection interface can be a connection method of different pitch pins and / or sockets and / or flexible flat cable (FFC) sockets, and can provide external connection in one type or multiple types.
[0042] In the embodiment, the second Type-C socket module 111 and the first Type-C socket module 102 are connected through a data line. The second Type-C socket module 111 is used to connect with one or more communication interface pins and debugging interface pins of one or more chips.
[0043] The second Type-C socket module 111 is used to collect interface signals of one or more communication interface pins and debugging interface pins of one or more chips, and transmit the interface signals of the one or more chips to the first Type-C socket module 102, so that the interface splitting module 101 splits the interface signals of the one or more chips obtained by the first Type-C socket module 102, and then the debugging circuit is used to debug the one or more chips.
[0044] In the embodiment, as shown in Figure 1 The second Type-C socket module 111 includes a pin CC1 corresponding to a fast charging protocol PD in a universal serial bus standard USB. The second Type-C socket module 111 is connected with the anti-reverse plug detection module 112 through the pin CC1.
[0045] In the embodiment, the connection establishment prompt module 113 is connected with the anti-reverse plug detection module 112.
[0046] The anti-reverse plug detection module 112 determines whether the forward connection is successful by detecting the voltage value of the pin CC1. After the anti-reverse plug detection module 112 determines that the forward connection is successful, the anti-reverse plug detection module 112 sends a forward connection success output signal to the connection establishment prompt module 113. The connection establishment prompt module 113 sends a prompt signal according to the forward connection success output signal, so as to prompt the staff that the interface forward connection is successful.
[0047] Preferably, the anti-reverse plug detection module 112 detects the voltage value of the pin CC1, and compares the voltage value with a reference voltage value Vref to determine whether the forward connection is successful. After the anti-reverse plug detection module 112 determines that the forward connection is successful, the anti-reverse plug detection module 112 sends a forward connection success output signal to the connection establishment prompt module 113.
[0048] Optionally, the connection establishment prompt module 113 includes a signal lamp prompt circuit, the signal lamp prompt circuit includes an LED lamp, and the LED lamp is lit when the forward connection success output signal is a high-level signal.
[0049] Optionally, the connection establishment prompt module includes a buzzer prompt circuit, the buzzer prompt circuit includes a buzzer, and the buzzer starts to work in a sound state when the forward connection success output signal is a high-level signal.
[0050] The buzzer starts to work in a sound state when the forward connection success output signal is a high-level signal.
[0051] In the embodiment, the anti-reverse insertion detection module 112 realizes the anti-reverse insertion detection function through a comparator. Specifically, the anti-reverse insertion detection module 112 is connected with the connection establishment prompt module 113 through an output pin of the comparator.
[0052] The first Type-C socket module 102 and the second Type-C socket module 111 are connected with each other through a Type-C data line. When the first Type-C socket module 102 and the second Type-C socket module 111 are connected according to the one-to-one matching of the same pin name definition, the anti-reverse insertion detection module 112 detects that the pin CC1 of the second Type-C socket module 111 is at a high level, which is higher than the comparison voltage Vref (i.e., the reference voltage value Vref) of the comparator inside the anti-reverse insertion detection module 112. The output pin of the comparator of the anti-reverse insertion detection module 112 outputs a high level. The high level signal is a forward connection success output signal. When the connection establishment prompt module 113 receives the high level signal output from the output pin of the comparator, the connection establishment prompt module 113 reminds the staff through an LED lamp, a buzzer and the like, and informs the staff that the connection is successfully established and the wire insertion direction is correct.
[0053] When the first Type-C socket module 102 and the second Type-C socket module 111 are not connected according to the one-to-one matching of the same pin name definition, the anti-reverse insertion detection module 112 detects that the pin CC1 of the second Type-C socket module 111 is at a low level, which is lower than the comparison voltage Vref (i.e., the reference voltage value Vref) of the comparator inside the anti-reverse insertion detection module 112. The output pin of the comparator of the anti-reverse insertion detection module 112 outputs a low level. When the connection establishment prompt module 113 receives the low level signal output from the output pin of the comparator, the LED lamp cannot be lit and the buzzer cannot sound, thereby informing the staff that the connection is failed and the wire insertion direction is reversed.
[0054] In the above implementation mode, the anti-reverse insertion detection module 112 realizes the anti-reverse insertion detection function through a comparator. The anti-reverse insertion detection module 112 detects the voltage value of the pin CC1, compares the voltage value with the reference voltage value Vref through the comparator, and determines whether the forward connection is successful. After the anti-reverse insertion detection module 112 determines that the forward connection is successful, the anti-reverse insertion detection module 112 sends a forward connection success output signal to the connection establishment prompt module 113.
[0055] In other implementation modes, optionally, please refer to Figure 2 , Figure 2Another system architecture diagram of the debugging circuit based on the Type-C interface is provided for the embodiment of the utility model. The anti-reverse insertion detection module 112 includes an input communication interface IN3, a first output communication interface OUT1, and a second output communication interface OUT2. All communication interfaces of the second Type-C socket module 111 are connected in one-to-one correspondence with all first output communication interfaces OUT1 of the anti-reverse insertion detection module 112 in a first connection order, and all communication interfaces of the second Type-C socket module 111 are connected in one-to-one correspondence with all second output communication interfaces OUT2 of the anti-reverse insertion detection module 112 in a second connection order. The first connection order is a forward sequence connection, and the second connection order is a reverse sequence connection.
[0056] In the embodiment, the second Type-C socket module 111 is connected with one or more communication interface pins and debugging interface pins of one or more chips through the input communication interface IN3 of the anti-reverse insertion detection module 112.
[0057] The anti-reverse insertion detection module 112 determines whether the forward connection is successful by detecting the voltage value of the pin CC1. After the anti-reverse insertion detection module 112 determines that the forward connection is successful, the second output communication interface OUT2 is closed. If the anti-reverse insertion detection module 112 determines that the forward connection is not successful, the first output communication interface OUT1 is closed.
[0058] Specifically, when the first Type-C socket module 102 and the second Type-C socket module 111 are connected in one-to-one correspondence according to the same pin name definition, the anti-reverse insertion detection module 112 detects that the pin CC1 of the second Type-C socket module 111 is at a high level, that is, the anti-reverse insertion detection module 112 determines that the forward connection is successful, and the second output communication interface OUT2 is closed. When the first Type-C socket module 102 and the second Type-C socket module 111 are not connected in one-to-one correspondence according to the same pin name definition, the anti-reverse insertion detection module 112 detects that the pin CC1 of the second Type-C socket module 111 is at a low level, that is, the anti-reverse insertion detection module 112 determines that the forward connection is not successful, and the first output communication interface OUT1 is closed.
[0059] In the embodiment, the main difference from the above-mentioned Figure 1 The main difference between the embodiment shown in the figure and the above-mentioned embodiment is that the second Type-C socket module 111 is connected with the anti-reverse insertion detection module 112 through the first output communication interface OUT1 and the second output communication interface OUT2, and the anti-reverse insertion detection module 112 is connected with the single board of the electronic hardware product through the input communication interface IN3. Specifically, the anti-reverse insertion detection module 112 is connected with one or more communication interface pins and debugging interface pins of one or more chips on the single board of the electronic hardware product through the input communication interface IN3.
[0060] In the embodiment, when the first Type-C socket module 102 and the second Type-C socket module 111 are connected one by one according to the same pin name definition through the Type-C data line, the anti-reverse plug detection module 112 detects that the pin CC1 of the second Type-C socket module 111 is at a high level, on the one hand, the anti-reverse plug detection module 112 controls the output pin of the comparator to output a high level, and on the other hand, decides that the first output communication interface OUT1 is used as the signal input end of the second Type-C socket module 111.
[0061] Optionally, in the embodiment, when the anti-reverse plug detection module 112 receives the output pin of the comparator outputting a high level, the connection establishment prompt module 113 prompts the staff through an LED lamp, a buzzer and the like, and informs the staff that the connection is successfully established and the wire direction is correct.
[0062] In the embodiment, when the anti-reverse plug detection module 112 detects that the pin CC1 of the second Type-C socket module 111 is at a low level, on the one hand, the anti-reverse plug detection module 112 controls the output pin of the comparator to output a low level, and on the other hand, decides that the second output communication interface OUT2 is used as the signal input end of the second Type-C socket module 111.
[0063] Optionally, in the embodiment, when the anti-reverse plug detection module 112 receives the output pin of the comparator outputting a low level, the connection establishment prompt module 113 cannot light the LED lamp and cannot make the buzzer sound, thereby informing the staff that the connection fails and the wire direction is reversed.
