Lightweight USB Device Stack

  • Lightweight and fast
  • Event-driven process workflow
  • Completely separated USB hardware driver and usb core
  • Easy to use.

  1. Single physical endpoint can be used to implement
  • one bi-directional/single-buffer logical endpoint (CONTROL)
  • one uni-directional/double-buffer logical endpoint (BULK OR ISOCHRONOUS)
  • two uni-directional/single-buffer logical endpoints (BULK OR INTERRUPT)
  1. At this moment BULK IN endpoint can use both buffers, but it is not real doublebuffered.

  2. Tested with STM32L052K8, STM32L100RC, STM32L476RG, STM32F072C8, STM32F103C8, STM32F103CB, STM32F303CC, STM32F303RE, STM32F429ZI, STM32F105RBT6, STM32F107VCT6, STM32L433CCT6, STM32F070CBT6, STM32G431RB

Implemented definitions for classes

  1. USB HID based on Device Class Definition for Human Interface Devices (HID) Version 1.11
  2. USB DFU based on USB Device Firmware Upgrade Specification, Revision 1.1
  3. USB CDC based on Class definitions for Communication Devices 1.2

Using makefile

  • to build library module
make module MODULE=path/module.a DEFINES="mcu spcified defines" CFLAGS="cpu cpecified compiler flags"
  • to build demo
make bluepill program
make stm32l052x8
  • to get a help
make help
