+
+CherryUSB is a tiny, beautiful and portable USB host and device stack for embedded system with USB IP.
+
+![CherryUSB](CherryUSB.svg)
+
+## Why choose
+
+### Easy to study USB
+
+In order to make it easier for users to learn USB basics, enumeration, driver loading and IP drivers, the code has been written with the following advantages:
+
+- Lean code, simple logic, no complex C syntax
+- Tree-based programming with cascading code
+- Class-drivers and porting-drivers are templating and simplification
+- Clear API classification (slave: initialisation, registration api, command callback api, data sending and receiving api; host: initialisation, lookup api, data sending and receiving api)
+
+### Easy to use  USB
+
+In order to facilitate the use of the USB interface and to take into account the fact that users have learned about uart and dma, the following advantages have been designed for the data sending and receiving class of interface:
+
+- Equivalent to using uart tx dma/uart rx dma
+- There is no limit to the length of send and receive, the user does not need to care about the USB packetization process (the porting driver does the packetization process)
+
+### Easy to bring out USB performance
+
+Taking into account USB performance issues and trying to achieve the theoretical bandwidth of the USB hardware, the design of the data transceiver class interface has the following advantages:
+
+- Porting drivers directly to registers, no abstraction layer encapsulation
+- Memory zero copy
+- If IP has DMA then uses DMA mode (DMA with hardware packetization)
+- Unlimited length make it easier to interface with hardware DMA and take advantage of DMA
+- Subcontracting function is handled in interrupt

+## Device Stack Overview
+
+CherryUSB Device Stack provides a unified framework of functions for standard device requests, CLASS requests, VENDOR requests and custom special requests. The object-oriented and chained approach allows the user to quickly get started with composite devices without having to worry about the underlying logic. At the same time, a standard dcd porting interface has been standardised for adapting different USB IPs to achieve ip-oriented programming.
+
+CherryUSB Device Stack has the following functions：
+
+- Support USB2.0 full and high speed, USB3.0 super speed
+- Support endpoint irq callback register by users, let users do whatever they wants in endpoint irq callback.
+- Support Composite Device
+- Support Communication Device Class (CDC_ACM, CDC_ECM)
+- Support Human Interface Device (HID)
+- Support Mass Storage Class (MSC)
+- Support USB VIDEO CLASS (UVC1.0、UVC1.5)
+- Support USB AUDIO CLASS (UAC1.0、UAC2.0)
+- Support Device Firmware Upgrade CLASS (DFU)
+- Support USB MIDI CLASS (MIDI)
+- Support Remote NDIS (RNDIS)
+- Support WINUSB1.0、WINUSB2.0(with BOS)
+- Support Vendor class
+- Support multi device with the same USB IP

+
+## Host Stack Overview
+
+The CherryUSB Host Stack has a standard enumeration implementation for devices mounted on roothubs and external hubs, and a standard interface for different Classes to indicate what the Class driver needs to do after enumeration and after disconnection. A standard hcd porting interface has also been standardised for adapting different USB IPs for IP-oriented programming. Finally, the host stack is managed using os, and provides osal to make a adaptation for different os.
+
+CherryUSB Host Stack has the following functions：
+
+- Automatic loading of supported Class drivers
+- Support blocking transfers and asynchronous transfers
+- Support Composite Device
+- Multi-level HUB support, expandable up to 7 levels(Testing hub with 10 ports works well,only support dwc2 and ehci now)
+- Support Communication Device Class (CDC_ACM, CDC_ECM)
+- Support Human Interface Device (HID)
+- Support Mass Storage Class (MSC)
+- Support USB Video CLASS (commercial charge)
+- Support USB Audio CLASS (commercial charge)
+- Support Remote NDIS (RNDIS)
+- Support USB Bluetooth class (support nimble and zephyr bluetooth stack, support **CLASS:0xE0** or vendor class like cdc acm)
+- Support Vendor class
+- Support USB modeswitch
+- Support multi host with the same USB IP
+
+The CherryUSB Host stack also provides the lsusb function, which allows you to view information about all mounted devices, including those on external hubs, with the help of a shell plugin.

+# CherryUSB
+
+[English](./README.md)
+
+CherryUSB 是一个小而美的、可移植性高的、用于嵌入式系统(带 USB IP)的 USB 主从协议栈。
+
+![CherryUSB](CherryUSB.svg)
+
+## 为什么选择
+
+### 易于学习 USB
+
+为了方便用户学习 USB 基本知识、枚举、驱动加载、IP 驱动，因此，编写的代码具备以下优点：
+
+- 代码精简，逻辑简单，无复杂 C 语言语法
+- 树状化编程，代码层层递进
+- Class 驱动和 porting 驱动模板化、精简化
+- API 分类清晰（从机：初始化、注册类、命令回调类、数据收发类；主机：初始化、查找类、数据收发类）
+
+### 易于使用 USB
+
+为了方便用户使用 USB 接口，考虑到用户学习过 uart 和 dma，因此，设计的数据收发类接口具备以下优点：
+
+- 等价于使用 uart tx dma/uart rx dma
+- 收发长度没有限制，用户不需要关心 USB 分包过程（porting 驱动做分包过程）
+
+### 易于发挥 USB 性能
+
+考虑到 USB 性能问题，尽量达到 USB 硬件理论带宽，因此，设计的数据收发类接口具备以下优点：
+
+- Porting 驱动直接对接寄存器，无抽象层封装
+- Memory zero copy
+- IP 如果带 DMA 则使用 DMA 模式（DMA 带硬件分包功能）
+- 长度无限制，方便对接硬件 DMA 并且发挥 DMA 的优势
+- 分包功能在中断中处理
+

+
+## Device 协议栈简介
+
+CherryUSB Device 协议栈对标准设备请求、CLASS 请求、VENDOR 请求以及 custom 特殊请求规范了一套统一的函数框架，采用面向对象和链表的方式，能够使得用户快速上手复合设备，不用管底层的逻辑。同时，规范了一套标准的 dcd porting 接口，用于适配不同的 USB IP，达到面向 ip 编程。
+
+CherryUSB Device 协议栈当前实现以下功能：
+
+- 支持 USB2.0 全速和高速设备，USB3.0 超速设备
+- 支持端点中断注册功能，porting 给用户自己处理中断里的数据
+- 支持复合设备
+- 支持 Communication Device Class (CDC_ACM, CDC_ECM)
+- 支持 Human Interface Device (HID)
+- 支持 Mass Storage Class (MSC)
+- 支持 USB VIDEO CLASS (UVC1.0、UVC1.5)
+- 支持 USB AUDIO CLASS (UAC1.0、UAC2.0)
+- 支持 Device Firmware Upgrade CLASS (DFU)
+- 支持 USB MIDI CLASS (MIDI)
+- 支持 Remote NDIS (RNDIS)
+- 支持 WINUSB1.0、WINUSB2.0(带 BOS )
+- 支持 Vendor 类 class
+- 支持相同 USB IP 的多从机

+## Host 协议栈简介
+
+CherryUSB Host 协议栈对挂载在 roothub、外部 hub 上的设备规范了一套标准的枚举实现，对不同的 Class 类也规范了一套标准接口，用来指示在枚举后和断开连接后该 Class 驱动需要做的事情。同时，规范了一套标准的 hcd porting 接口，用于适配不同的 USB IP，达到面向 IP 编程。最后，协议栈使用 OS 管理，并提供了 osal 用来适配不同的 os。
+
+CherryUSB Host 协议栈当前实现以下功能：
+
+- 自动加载支持的Class 驱动
+- 支持阻塞式传输和异步传输
+- 支持复合设备
+- 支持多级 HUB,最高可拓展到 7 级(目前测试 1拖 10 没有问题，当前仅支持 dwc2 和 ehci)
+- 支持 Communication Device Class (CDC_ACM, CDC_ECM)
+- 支持 Human Interface Device (HID)
+- 支持 Mass Storage Class (MSC)
+- Support USB Video CLASS（商业收费）
+- Support USB Audio CLASS（商业收费）
+- 支持 Remote NDIS (RNDIS)
+- 支持 USB Bluetooth (支持 nimble and zephyr bluetooth 协议栈，支持 **CLASS: 0xE0** 或者厂家自定义类，类似于 cdc acm 功能)
+- 支持 Vendor 类 class
+- 支持 USB modeswitch
+- 支持相同 USB IP 的多主机
+
+同时，CherryUSB Host 协议栈还提供了 lsusb 的功能，借助 shell 插件可以查看所有挂载设备的信息，包括外部 hub 上的设备的信息。
