如何生成示例程序 How to make demo

编译工具为 arm-none-eabi-gcc is the compile toolchain.

调试使用VSCode+OpenOCD，如何在VSCode中配置STM32开发调试环境?

git clone https://github.com/xtoolbox/TeenyUSB.git
cd TeenyUSB
git submodule update --init
cd sample
make all -j8

如果更新mcu库很慢，可以使用gitee.com镜像。https://gitee.com/xtoolbox/st_driver.git

其它支持STM32的开源USB协议栈 Other open source USB stack for STM32

tinyusb 全静态内存分配，不支持多设备，不支持同一设备上使用多个同类型接口，暂时不支持STM32主机模式。
libopencm3 动态生成描述符，不依赖官方库。USB设备类型少，不支持主机模式。
libusb_stm32 资源占用极少的USB设备库，不支持主机模式。

其它嵌入式开源USB协议栈

lufa 运行于AVR的轻量级USB主机和从机栈。
