Implement full SSD1306 OLED display support: - Splash screen on boot (1.5s) with project name, version, board - Dashboard showing radio state, config, counters, RSSI/SNR - RSSI history sparkline (64-sample ring buffer, 2px-wide bars) - DisplayOn/DisplayOff host commands routed via dedicated channel - Pure render functions against generic DrawTarget (no hardware coupling) - Display on/off control bypasses radio task entirely Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

usb-device
USB stack for embedded devices in Rust.
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 driver to implement the USB device.
The UsbClass trait can be used to implement 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.
