TinyUSB is an open-source cross-platform USB Host/Device stack for embedded system, designed to be memory-safe with no dynamic allocation and thread-safe with all interrupt events are deferred then handled in the non-ISR task function.

[Here is the list of supported Boards](docs/boards.md) that can be used with provided examples.
|
|
|
|
## Device Stack
|
|
|
|
Supports multiple device configurations by dynamically changing usb descriptors. Low power functions such like suspend, resume, and remote wakeup. Following device classes are supported:
|
|
|
|
- Audio Class 2.0 (UAC2) still work in progress
|
|
- Bluetooth Host Controller Interface (BTH HCI)
|
|
- Communication Class (CDC)
|
|
- Device Firmware Update (DFU): DFU mode (WIP) and Runtinme
|
|
- Human Interface Device (HID): Generic (In & Out), Keyboard, Mouse, Gamepad etc ...
|
|
- Mass Storage Class (MSC): with multiple LUNs
|
|
- Musical Instrument Digital Interface (MIDI)
|
|
- Network with RNDIS, CDC-ECM (work in progress)
|
|
- USB Test and Measurement Class (USBTMC)
|
|
- Vendor-specific class support with generic In & Out endpoints. Can be used with MS OS 2.0 compatible descriptor to load winUSB driver without INF file.
|
|
- [WebUSB](https://github.com/WICG/webusb) with vendor-specific class
|
|
|
|
If you have special need, `usbd_app_driver_get_cb()` can be used to write your own class driver without modifying the stack. Here is how RPi team add their reset interface [raspberrypi/pico-sdk#197](https://github.com/raspberrypi/pico-sdk/pull/197)
|
|
|
|
## Host Stack
|
|
|
|
**Most active development is on the Device stack. The Host stack is under rework and largely untested.**
|
|
|
|
- Human Interface Device (HID): Keyboard, Mouse, Generic
|
|
- Mass Storage Class (MSC)
|
|
- Hub currently only supports 1 level of hub (due to my laziness)
|
|
|
|
## OS Abstraction layer
|
|
|
|
TinyUSB is completely thread-safe by pushing all ISR events into a central queue, then process it later in the non-ISR context task function. It also uses semaphore/mutex to access shared resources such as CDC FIFO. Therefore the stack needs to use some of OS's basic APIs. Following OSes are already supported out of the box.
|
|
|
|
- **No OS**
|
|
- **FreeRTOS**
|
|
- **Mynewt** Due to the newt package build system, Mynewt examples are better to be on its [own repo](https://github.com/hathach/mynewt-tinyusb-example)
|

|
## Getting Started
|
|
|
|
[Here are the details for getting started](docs/getting_started.md) with the stack.
