10 * LUFA is not the only stack available for the USB AVRs, although it is perhaps the best (see \ref Page_WhyUseLUFA).
11 * In the interests of completeness and user choice, other known USB AVR stacks are listed here.
13 * \section Sec_HardwareStacks Hardware USB AVR Stacks
14 * These are the known alternative USB stacks which are designed for and run exclusively on the USB AVR series microcontrollers,
15 * which contain on-chip USB controller hardware for maximum features and speed.
17 * - <b>Name:</b> Atmel USB AVR Stack (<i>Atmel Inc.</i>) \n
18 * <b>Cost:</b> Free \n
19 * <b>License:</b> Atmel Limited License (see Atmel download for details) \n
20 * <b>Website:</b> http://atmel.com/dyn/products/app_notes.asp?family_id=607#USB \n
21 * <b>Description:</b> This is the official Atmel USB AVR stack, for their 8-bit USB AVR lineup. Each series of
22 * USB AVR is separated into a separate download stack, which is both AVR-GCC and IAR compatible.
24 * - <b>Name:</b> Dr. Stefan Salewski's AT90USB1287 Stack (<i>Dr. Stefan Salewski</i>) \n
25 * <b>Cost:</b> Free \n
26 * <b>License:</b> GPL \n
27 * <b>Website:</b> http://www.ssalewski.de/AT90USB_firmware.html.en \n
28 * <b>Description:</b> This is a GPL'd library specifically designed for the AT90USB1287, by Dr. Stefan Salewski, a
29 * German Physicist. It compiles for AVR-GCC and can potentially be modified to work on other USB
32 * - <b>Name:</b> FreakUSB Stack (<i>FreakLabs</i>) \n
33 * <b>Cost:</b> Free \n
34 * <b>License:</b> Modified BSD \n
35 * <b>Website:</b> http://freaklabs.org/index.php/FreakUSB-Open-Source-USB-Device-Stack.html \n
36 * <b>Description:</b> An open source simple USB stack for a selection of the USB AVRs. Contains a sample class driver
37 * for the CDC-ACM class, however other class driver implementations are also possible.
39 * - <b>Name:</b> PJRC Teensy Stack (<i>Paul Stoffregen</i>) \n
40 * <b>Cost:</b> Free \n
41 * <b>License:</b> BSD \n
42 * <b>Website:</b> http://www.pjrc.com/teensy/usb_debug_only.html \n
43 * <b>Description:</b> Not so much a complete stack as a collection of USB enabled demos, this library is specifically
44 * designed for the PJRC Teensy line of USB AVRs, and thus may need to be modified for other USB AVR
45 * chips. These minimal code samples shows the inner workings of the USB controller, without all the
46 * abstraction present in most other USB AVR stacks.
48 * \section Sec_SoftwareStacks Software AVR Stacks
49 * These are the known alternative USB stacks which can run on regular AVR models, lacking dedicated hardware USB controllers
50 * via a bit-banged (emulated) version of the USB protocol. They are limited in their capabilities due to the cycles required
51 * to be dedicated to managing the USB bus, but offer a cheap way to implement USB functionality into a design.
53 * - <b>Name:</b> AVR309: Software USB (<i>Atmel</i>) \n
54 * <b>Cost:</b> Free \n
55 * <b>License:</b> None Stated \n
56 * <b>Website:</b> http://www.atmel.com/dyn/Products/app_notes.asp?family_id=607 \n
57 * <b>Description:</b> Atmel's official software USB implementation, an Application Note containing work by Igor Cesko. This
58 * is a minimal assembly-only implementation of software USB, providing HID functionality. Less compile
59 * options than V-USB (see below).
61 * - <b>Name:</b> V-USB (<i>Objective Development</i>) \n
62 * <b>Cost:</b> Free for some uses, see website for licensing \n
63 * <b>License:</b> Dual GPL2/Custom \n
64 * <b>Website:</b> http://www.obdev.at/products/vusb/index.html \n
65 * <b>Description:</b> Well regarded and complete USB 1.1 software stack for several AVR models, implementing Low Speed HID.
66 * Used in many commercial and non-commercial designs, with user-submitted projects available for viewing
67 * on the company's website. Uses C language code mixed with assembly for time-critical sections.
