PlatformIO+GD32
想要对GD32进行开发，需要在PlatformIO中添加GD32的芯片支持，GD32官方支持库存在于Github，原文如下：
See example projects at https://github.com/CommunityGD32Cores/gd32-pio-projects.
The platform can be installed manually using
pio platform install https://github.com/CommunityGD32Cores/platform-gd32.git on the CLI. This is done automatically when compiling one of the example projects.
需要在PlatformIO终端内执行如下命令：
pio platform install https://github.com/CommunityGD32Cores/platform-gd32.git
vscode中打开终端的方法为：
cmd+shift+p打开命令窗口- 输入
PlatformIO: Open PlatformIO Core CLI - 在打开的终端中执行上述命令
