There are Keil version and IAR version of all projects. Keil version of the projects are created
based on Keil MDK-ARM 4.74 uVision4. IAR version of the projects are created based on
IAR Embedded Workbench for ARM 7.40.2. During use, the following points should be
noted:
1. If you use Keil uVision4 to open the project, install the GD32F3x0_AddOn.2.0.0.exe to
load the associated files.
2. If you use Keil uVision5 to open the project, there are two ways to solve the "Device
