LanguageProject Introduction
Summary
TinyUSB is a robust and highly portable open-source USB stack specifically designed for resource-constrained embedded systems, providing comprehensive support for both device and host modes with a focus on ease of use and low resource consumption.
Problem Solved
Developing USB functionality for embedded systems is often complex and requires deep understanding of USB protocols and specific hardware. TinyUSB abstracts this complexity, providing a simplified API and ready-to-use class drivers.
Core Features
Dual Role Support (Host/Device)
Supports both USB Host and Device modes concurrently for flexible connectivity options.
Rich Class Support
Includes extensive support for standard USB classes such as CDC, HID, MSC, MIDI, DFU, and more.
Cross-Platform Compatibility
Designed with a hardware abstraction layer (HAL) facilitating easy porting to a wide range of microcontrollers.
Low Resource Usage
Optimized for minimal RAM and Flash usage, making it highly suitable for resource-constrained embedded systems.
Tech Stack
C/C++
ARM Cortex-M
RISC-V
ESP32
CMake
Make
使用场景
TinyUSB is ideal for embedded projects requiring standard or complex USB connectivity in various applications:
场景一：构建标准USB设备
Details
Implement standard USB devices such as CDC serial ports, HID keyboards/mice, or MSC mass storage devices on resource-constrained microcontrollers.
User Value
Rapidly add standard USB device functionality without writing complex low-level protocol code, speeding up development.
场景二：开发USB Host应用
Details
Enable embedded systems to act as USB Hosts to communicate with USB peripherals like keyboards, mice, or mass storage drives (e.g., logging data to a USB stick).
User Value
Allow embedded devices to easily interact with and control a wide range of off-the-shelf USB peripherals.
场景三：创建自定义USB设备
Details
Develop custom USB devices with vendor-specific functionalities for unique hardware or communication requirements.
User Value
Provides the flexibility and framework to define and implement custom USB protocols tailored to specific application needs.
