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

|
## Device Stack
|
|
|
|
Support multiple device configurations by dynamically changing usb descriptors. Low power functions such as suspend, resume and remote wakeup. Following device classes are supported:
|
|
|
|
- Communication Class (CDC)
|
|
- Human Interface Device (HID): Generic (In & Out), Keyboard, Mouse, Gamepad etc ...
|
|
- Mass Storage Class (MSC): with multiple LUNs
|
|
- Musical Instrument Digital Interface (MIDI)
|
|
- 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
|
|
|
|
## 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 support 1 level of hub (due to my laziness)
|
|
|
|
## OS Abtraction layer
|
|
|
|
Currently the following OS are supported with tinyusb out of the box with a simple change of **CFG_TUSB_OS** macro.
|
|
|
|
- **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)
|
|
|
|
## Supported MCUs
|
|
|
|
The stack supports the following MCUs
|
|
|
|
- **Nordic:** nRF52840
|
|
- **NXP:** LPC11Uxx, LPC13xx, LPC175x_6x, LPC177x_8x, LPC18xx, LPC40xx, LPC43xx, LPC51Uxx
|
|
- **MicroChip:** SAMD21, SAMD51 (device only)
|
|
- **ST:** STM32F4 (device only)
|
|
|
|
[Here is the list of supported Boards](docs/boards.md)
|
|
|
|
## Compiler & IDE
|
|
|
|
The stack is developed with GCC compiler, and should be compilable with others. Folder `examples` provide Makefile and Segger Embedded Studio build support.
|
|
|
|
## Getting Started
|
|
|
|
[Here is the details for getting started](docs/getting_started.md) with the stack.
|
|
|
|
## Porting
|
|
|
|
Want to help add TinyUSB support for a new MCU? Read [here](docs/porting.md) for an explanation on the low-level API needed by TinyUSB.
