James Laird-Wah 39bd760faf Use a single endpoint for HID reports (#3951)
* Unify multiple HID interfaces into one

This reduces the number of USB endpoints required, which frees them up
for other things.

NKRO and EXTRAKEY always use the shared endpoint.

By default, MOUSEKEY also uses it. This means it won't work as a Boot
Procotol mouse in some BIOSes, etc. If you really think your
keyboard needs to work as a mouse in your BIOS, set
MOUSE_SHARED_EP = no in your rules.mk.

By default, the core keyboard does not use the shared endpoint, as not
all BIOSes are standards compliant and that's one place you don't want
to find out your keyboard doesn't work.. If you are really confident,
you can set KEYBOARD_SHARED_EP = yes to use the shared endpoint here
too.

* unify endpoints: ChibiOS protocol implementation

* fixup: missing #ifdef EXTRAKEY_ENABLEs

broke build on AVR with EXTRAKEY disabled

* endpoints: restore error when too many endpoints required

* lufa: wait up to 10ms to send keyboard input

This avoids packets being dropped when two reports are sent in quick
succession (eg. releasing a dual role key).

* endpoints: fix compile on ARM_ATSAM

* endpoint: ARM_ATSAM fixes

No longer use wrong or unexpected endpoint IDs

* endpoints: accommodate VUSB protocol

V-USB has its own, understandably simple ideas about the report formats.
It already blasts the mouse and extrakeys through one endpoint with
report IDs. We just stay out of its way.

* endpoints: document new endpoint configuration options

* endpoints: respect keyboard_report->mods in NKRO

The caller(s) of host_keyboard_send expect to be able to just drop
modifiers in the mods field and not worry about whether NKRO is in use.
This is a good thing. So we just shift it over if needs be.

* endpoints: report.c: update for new keyboard_report format

TMK Keyboard Firmware Core Library

This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.

Source code is available here: https://github.com/tmk/tmk_keyboard/tree/master/tmk_core

Updates

2016/02/10

flabbergast's Chibios protocol was merged from https://github.com/flabbergast/tmk_keyboard/tree/chibios. See protocol/chibios/README.md. Chibios protocol supports Cortex-M such as STM32 and Kinetis.

Debugging

Use PJRC's hid_listen to see debug messages. You can use the tool for debug even if firmware use LUFA stack.

You can use xprintf() to display debug info on hid_listen, see common/xprintf.h.
