EDA project: System board designed using GD32F103CBT6 chip

        This project is an integrated circuit chip that uses very large scale integrated circuit technology to combine a central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, various I/O ports and interrupt systems, timers/timing A small but complete computer system is formed by integrating functions such as display driver circuits, pulse width modulation circuits, analog multiplexers, A/D converters and other circuits on a silicon chip.

        This project is a system board designed using the GD32F103CBT6 chip, which leads to the USB 2.0 full-speed Device interface, the PDI debugging interface, all GPIO pins, and has two LED indicators, two user buttons and a reset button on the board.

         Instructions for use: To program the GD32F103CBT6 chip, plug in the serial port cable and USB cable or external power supply, open the STC-I SP programming software in the random CD, follow the steps on the software, after setting, first press SP-28USB Turn on the power button and turn on the power supply. Then press the "Chip Programming" button on the software to power on the SP-28USB system. At this time, the built-in reset circuit of the STC microcontroller will automatically connect to the computer and you can write your own program and use it. .
