[CNX-Software] - CherryUSB – A lightweight USB device/host stack for embedded systems

CherryUSB is a lightweight open-source USB device/host stack for embedded systems with one or more USB interfaces. The stack implements various class drivers such as CDC, HID, MSC, audio, video, and so on. It’s apparently part of Boufalla Labs SDK (e.g. for BL702 MCU), and has been ported and tested with WCH CH32V307 RISC-V MCU, STMicro STM32F4, and Nuvoton NUC442 Cortex-M4 microcontroller, as well as a two Arm Cortex-M3 microcontrollers I’ve never heard of: EastSoft ES32F3 and MindMotion MM32L3xx. CherryUSB device stack highlights: Support for USB2.0 full and high speed Endpoint irq callback USB classes support Composite Device Communication Device Class (CDC) Human Interface Device (HID) including “Custom HID” Mass Storage Class (MSC) USB VIDEO Class (UVC1.0,UVC1.5) USB AUDIO Class (UAC1.0, UAC2.0) Device Firmware Upgrade CLASS (DFU) MIDI CLASS (MIDI) Test and Measurement CLASS (TMC) Vendor class Remote NDIS (RNDIS) support Support WINUSB 1.0,WINUSB 2.0 with BOS (Binary Device Object [...]
