[0031] Example 1

[0032] See Figure 1 :

[0033] A universal integrated debugging interface for multi-processor motherboards in industrial machine tools includes a motherboard end and a debugging board end. Both the motherboard end and the debugging board end are provided with FPC connectors, which connect the motherboard end and the debugging board end. The FPC connector on the motherboard end integrates a programming interface, a debugging interface, an expansion interface, and a configuration interface. The FPC connector on the debugging board end integrates a USB signal interface, a 2.54 header pin, and the configuration interface of the debugging board end.

[0034] In one embodiment, the FPC socket used is a 10P 0.5 pitch FPC socket, which refers to an FPC socket with 10 pins and a pin spacing of 0.5 mm.

[0035] Furthermore,

[0036] The USB signal interface includes a TYPE-C signal interface and a USB-A signal interface;

[0038] It supports both Type-C and USB-A interfaces to adapt to the needs of different peripherals. Type-C supports USB 3.1 / 3.2 protocols, which can improve the efficiency of burning and communication. For example, in some real-time cases, the firmware transmission rate can reach more than 5Gbps.

[0039] At the same time, because of the existence of the USB signal interface, the existing USB interface can be expanded by relying on the USB hub to connect more debugging tools or peripherals (such as programmers and sensors) at the same time, thereby improving development efficiency.

[0040] Furthermore,

[0041] The 2.54 pin header is used to connect to other external devices.

[0042] The 2.54 header refers to its pin pitch of 2.54 mm. The 2.54 header allows for flexible expansion, and its standardized header interface can be connected to peripherals such as sensors, displays, and communication modules, supporting functional customization.

[0043] Furthermore,

[0044] Both the configuration interfaces on the debug board and the motherboard adopt a single-line configuration method, and the configuration interface on the debug board corresponds to the configuration interface on the motherboard, which is used to configure and set the debug board.

[0045] In some embodiments, the single-line configuration uses the 1-Wrie protocol for single-line communication, thereby reducing the complexity of wiring, lowering the probability of configuration errors, and making the synchronization between the debug board and the motherboard more efficient.

[0046] Furthermore,

[0047] The debugging interface is a debugging TTL serial port, used for transmitting debugging information and real-time debugging and monitoring.

[0048] The debugging interface uses a TTL serial port, and in some embodiments, a UART serial port is used. It can directly output raw data without level conversion, reducing signal transmission delay. It also has a wide range of compatibility, supporting the debugging needs of most embedded processors, such as ARM and STM32.

[0049] Furthermore,

[0050] The programming interface is used to program or firmware onto the motherboard.

[0051] A dedicated programming interface is also provided to avoid competing for bandwidth with other functions. It supports batch programming and resume interrupted downloads. In some embodiments, the programming interface is also equipped with encryption protocols such as AES to prevent the firmware from being illegally tampered with. The programming interface also supports a variety of standard protocols, such as JTAG and SWD, to adapt to different programming tools.

[0052] Furthermore,

[0053] The motherboard also has a power input interface and a power output interface.

[0054] The power input interface is used to supply power to the motherboard, and no additional power supply is required during program burning and simple debugging.

[0055] The power output interface is used to provide a stable power output and supports connection to external devices.

[0056] Example 2

[0057] like Figure 2 The circuit design shown is for the debug board. This circuit diagram uses a USB Type-C interface to implement power management, signal transmission, and circuit protection.

[0058] Interface section: It adopts interface J7 (model 503480-1000) for connecting external devices or power supply, including VBUS_TYPEC (power supply), TYPEC_D- and TYPEC_D+ (data transmission), EX_5V (external 5V power supply) and GND (ground) pins.

[0059] Power management section: The power management chip U58 (model WS4612EAC) is used to convert the input voltage into a stable 5V output (VSYS_5V), which includes VIN (input), VOUT (output), GND (ground), EN (enable), and ISET / NC (set or not connected) pins.

[0060] The capacitor and resistor section includes two 10μF / 16V electrolytic capacitors, C241 and C242, for power supply filtering; resistor R500 (10KΩ) for current limiting or voltage division; and resistor R499 (10KΩ) for enable control.

[0061] Signal transmission section: Includes USB signal pins DBG_USB_M and DBG_USB_P for debugging, and serial port signal pins M300_RXD_DBG and M300_TXD_DBG, with current limited by 100Ω resistors R244 and R245.

[0062] Protection circuit section: ESD protection diodes D64, D65, D66, D67, D68 and D69 (models ESD5302F and ESD5341N) are used and connected to each signal line to prevent electrostatic discharge from damaging the circuit.

[0063] This circuit receives an external 5V power supply through the EX_5V pin of J7, which, after current limiting by R500, is connected to the VIN pin of U58. U58 converts the input voltage to a stable 5V output, providing it to the system (VSYS_5V) via the VOUT pin. R499 is connected between VSYS_5V and the EN pin of U58 for enable control.

[0064] The data signals (TYPEC_D- and TYPEC_D+) of the TYPE-C interface are connected to external devices via J7 to achieve data transmission.

[0065] The USB signals (DBG_USB_M and DBG_USB_P) and serial port signals (M300_RXD_DBG and M300_TXD_DBG) used for debugging are connected to external debugging devices through corresponding pins for convenient system debugging. R244 and R245 are used to limit the current of the debugging signals and protect the circuit.

[0066] ESD protection diodes are connected to each signal line to prevent electrostatic discharge from damaging the circuit.

[0067] This embodiment connects to power and data signals via the J7 interface, utilizes the U58 power management chip to provide a stable 5V power supply, and ensures circuit safety through ESD protection diodes. The addition of debug signals makes the system more convenient and reliable during development and maintenance. The entire circuit is compact and fully functional, suitable for scenarios requiring debugging and power supply via a USB Type-C interface.

[0068] The principle of this utility model is as follows:

[0069] This utility model consists of a motherboard end and a debugging board end, both of which are connected via FPC connectors. In use, the user only needs to align and insert the FPC connector on the debugging board end with the FPC connector on the motherboard end to achieve electrical connection between the two ends.

[0070] The debug board integrates USB signal interfaces (both Type-C and USB-A), a 2.54-pin header, and a configuration interface. Users can connect debugging tools such as computers and programmers via the USB signal interfaces to program the motherboard, facilitate device communication, and perform high-speed data transfer using debugging software. Simultaneously, the 2.54-pin header provides flexible expansion interfaces for connecting external devices (such as sensors and displays) to meet diverse debugging and testing needs. The configuration interface uses a single-wire configuration method, allowing users to easily configure and control the debug board.

[0071] The motherboard integrates a programming interface, a debugging interface, an expansion interface, and a configuration interface. The programming interface is used to program or firmware onto the motherboard; the debugging interface supports the transmission of real-time debugging information, facilitating real-time debugging and monitoring for users; the expansion interface provides additional connection points, allowing users to expand the interface via devices such as USB hubs; and the configuration interface corresponds to the configuration interface on the debugging board, used to receive configuration commands from the debugging board.

[0072] It does not have various interfaces that are demanding on device conditions and can be further expanded using a USB Hub through expansion interfaces and USB interfaces, thus possessing a certain degree of expandability and versatility.
