emUSB-Device

emUSB-Device is a high speed USB device stack specifically designed for embedded systems. The software is written in ANSI C and can run on any platform. A variety of target drivers are already available. Support for new platforms can usually be added at no extra charge. 
emUSB-Device is available in two packages with differing components included.

Features

  • Optimized to be used with embOS but works with any other supported RTOS or even without an RTOS - in a super loop architecture (depending on the component used)
  • Easy to use
  • Easy to port
  • No custom USB host driver necessary
  • Start / test application supplied
  • Highly efficient, portable, and commented ANSI C source code
  • Hardware abstraction layer allows rapid addition of support for new devices

emUSB-Device components

emUSB-Device consists of three layers: A driver for hardware access, the emUSB-Device core and at least one USB class driver or the bulk communication component.

USB class drivers (MSD, CDC, HID, MTP, RNDIS), Bulk communication component, SmartMSD component and hardware drivers are separate packages, which can be combined and ordered individually to suit the requirements of any project.
