Teeny USB

A teeny USB stack for STM32 MCUs, also contain a toolset to create USB descriptors and drivers.

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

特性

1. 设备例程：串口，5路串口，自定义HID，自定义设备批量传输(无需驱动)。
2. 主机例程：无协议栈主机，键盘鼠标+HUB。
3. 使用lua脚本生成USB相关描述符，并根据描述符自动生成初始化配置代码。
4. 根据USB描述自动生成驱动文件，并对驱动文件签名。

Feature

1. Device demo: CDC, multiple CDC, Custom HID, Custom Bulk (No custom driver need, even no inf)
2. Host demo: raw host, hub+keyboard+mouse
3. USB descriptor generation by lua script and UI tool
4. Driver inf generation (based on libwdi)

TeenyDT版本描述符示例，Demo of descriptor in TeenyDT

return Device {
    strManufacture = "TeenyUSB",
    strProduct = "TeenyUSB CDC",
    strSerial = "TUSB123456",
    idVendor = 0x0483,
    idProduct = 0x0002,
    prefix = "CDC",
    Config {
        CDC_ACM{
            EndPoint(IN(3),  Interrupt,  64),
            EndPoint(IN(1),  BulkDouble, 64),
            EndPoint(OUT(2), BulkDouble, 64),
        },
   }
