********* Reference ********* .. figure:: ../assets/stack.svg :width: 1600px :alt: stackup representation of the TinyUSB stack. 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) - 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 `__ 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 ========== - 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) License ======= All TinyUSB sources in the `src` folder are licensed under MIT license. However, each file can be individually licensed especially those in `lib` and `hw/mcu` folder. Please make sure you understand all the license term for files you use in your project.
