Note: If the support package is not installed, the GigaDevice option will not appear, and the normal installation will appear

In the project folder directory

Add the header file path to let the compiler find the relevant header file and add the folder path where the corresponding header file is located to the project

4. The writing of the test code of the domestic single-chip microcomputer (GD32) library function

Open some necessary macro definitions, configure the project, GD32F10X_HD, __FPU_PRESENT

Note:
GPIOs that are not used by default need to be redirected
