Repository Details

Experimental device-side USB framework for microcontrollers in Rust.

usb-device

Experimental device-side USB stack for embedded devices in Rust.

This crate is still under development and should not be considered production ready or even USB compliant.

The UsbDevice object represents a composite USB device and is the most important object for application implementors. The UsbDevice combines a number of UsbClasses (either custom ones, or pre-existing ones provided by other crates) and a UsbBus device drives to implement the USB device.

The UsbClass trait can be used to implemented USB classes such as a HID device or a serial port. An implementation may also use a custom class if the required functionality isn't covered by a standard class.

The UsbBus trait is intended to be implemented by device-specific crates to provide a driver for each device's USB peripheral.

Hardware driver crates

  • atsam4 - device-driver implementation for atsam4e & atsam4s microcontrollers (UDP). Examples can be found here. While not expressly supported with this crate, atsam3s and atsam55g could also be supported with a similar code-base.

  • atsamd - device-driver implementation for samd21 & samd51 microcontrollers. An example for the itsybitsy_m4 board from Adafruit can be found here.

  • imxrt-usbd - device-driver implementation for NXP i.MX RT microcontrollers. Examples for i.MX RT boards, like the Teensy 4, are maintained with the driver.

  • stm32-usbd - device-driver implementation for multiple STM32 microcontroller families. Examples can be found in each individual HAL crate that implements the USB peripheral.

  • rp2040-hal - device-driver implementation for the raspberry pi RP2040 microcontroller. Examples can be found in the various boards crates here.

  • The Embassy project has an async USB stack, embassy-usb.
