Teeny USB

Build Status

一个简易的单片机USB主机和设备协议栈,现在支持3.0设备。

A teeny USB device and host stack for MCUs, support super speed device.

关于TeenyUSB的实现细节和使用方式请阅读《STM32 USB设备开发指南》 Github下载 , 21IC下载

设备栈 Device Stack

  • HID class
  • MSC 大容量存储设备,U盘。 Mass storage class
  • CDC ACM 虚拟串口。 Communication device class, abstract control mode, known as virtual serial port.
  • CDC RNDIS 虚拟网口。 Communication device class, remote NDIS
  • Vendor 厂商自定义设备。 vendor class

USB描述符由TeenyDT生成。 在线试用TeenyDT

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。
