[0036] The following is combined Figures 1 to 13 The following describes embodiments of the present invention.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in the figure, according to an embodiment of the utility model, an integrated circuit development board based on HYM32F103AVBT is provided, including a power supply module 2, a main controller MCU 1, and a BOOT module 3, an ADC module 6, a program loading module 4, a UART module 9, a clock module 5, a CAN module 10, an SPI module 11, an IIC module 12, a watchdog reset module 7, and an LED / button test module circuit 8, respectively connected to the main controller 1. The program loading module loads the written program code into the main controller. The power supply module includes a 5V power switch, a self-resetting fuse, a bidirectional transient suppression diode, a ripple capacitor, a linear regulator, and a power output voltage indicator LED to provide a stable operating voltage of 3.3V. The program loading module is a bridge between the development board and an external programming environment, such as a computer. It allows developers to quickly download their written C language program code to the main controller MCU of the development board. Through the program loading module, developers can quickly load and update program code on the development board, thereby performing code debugging in advance in the actual hardware environment. This allows developers to identify and resolve logical and syntax errors in the code early in the development process, thus avoiding hardware damage or functional abnormalities caused by code problems in actual circuit applications.

[0038] Power module 2 includes a 5V power switch, a resettable fuse, a bidirectional transient suppression diode, a filter capacitor, a linear regulator, and a power output voltage indicator LED. Program download module 4 loads the written program code into the main controller MCU 1 via JTAG / SWD communication. The program download module connects the development board to the external programming environment.

[0039] like Figure 4As shown, BOOT module 3 mainly connects the MCU's BOOT pin to a high or low level through a current-limiting resistor. The main function of this part is to select the BOOT boot mode, which is: boot from system memory, boot from main flash memory, or boot from embedded SRAM (internal SRAM).

[0040] like Figure 5 As shown, ADC module 6 includes a voltage reference chip, a 10KΩ adjustable potentiometer, a filter capacitor, and a current-limiting resistor. The voltage reference chip provides a precise and stable reference voltage to the VREF+ pin of MCU module 1, ensuring that the voltage value obtained after conversion of the ADC acquisition value is accurate and reliable. The 10KΩ adjustable potentiometer provides different voltage values ​​to the ADC acquisition of MCU module 1.

[0041] like Figure 6 As shown, program download module 4 primarily loads the written program code into the MCU via JTAG / SWD. Program download module 4 serves as the communication interface between the development board and the external computer programming environment, mainly loading the written program code into the internal memory of the main controller MCU via JTAG / SWD.

[0042] like Figure 7 As shown, UART module 9 includes a TYPE-C interface and a USB-to-UART chip. The main function of this part is to send the MCU's UART signals to the UART host computer via the USB converter chip and the TYPE-C interface, enabling information exchange between the MCU and the UART host computer. Additionally, a jumper cap can be used to switch the signal interface of the TYPE-C interface to the MCU's USB function pin to test the MCU's USB functionality.

[0043] like Figure 8 As shown, clock module 5 mainly consists of two active crystal oscillators, a low-speed 32.768KHz crystal oscillator and a high-speed 8MHz crystal oscillator. The function of this part is to provide a reliable clock signal for the stable operation of the MCU system.

[0044] like Figure 9 As shown, the main component of CAN module 10 is the CAN transceiver 65HVD230. The function of this part is to convert the CAN signal of the MCU into a differential signal through the CAN transceiver, so as to realize the information interaction between the MCU and the CAN bus.

[0045] like Figure 10As shown, the main component of SPI module 11 is the FLASH memory chip W25Q64JVSSSIQ. The function of this part is for the MCU to read and write to the FLASH memory chip through the SPI interface, thereby testing and verifying the MCU's SPI function.

[0046] like Figure 11 As shown, the main component of IIC module 12 is the EEPROM memory chip 24C02. The function of this part is for the MCU to read and write to the EEPROM memory chip through the IIC interface, thereby testing and verifying the IIC function of the MCU.

[0047] like Figure 12 As shown, the reset module 7 includes an RC button power-on reset circuit, a 6822TUK power monitoring / watchdog reset circuit chip, and a tri-state gate circuit, used to implement MCU power-on reset, manual reset, and voltage monitoring reset. The main function of this part is to initialize the MCU, allowing the MCU program to execute from the beginning. The watchdog power monitoring chip monitors whether the MCU's operating voltage is normal to ensure normal operation. When the voltage is lower than the 6822TUK's voltage threshold, a reset signal is generated to reset the MCU and prevent it from operating, thus preventing information processing errors caused by unstable MCU system operation.

[0048] like Figure 13 As shown, the LED of the LED / button test module 8 is connected to the MCU's IO port via a common anode current-limiting resistor, and the button is connected to the MCU's IO port via a current-limiting resistor connected to GND. This part of the circuit can test the MCU's high and low level output and input functions.

[0049] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation.
