massdrop alt/ctrl: support saving into nvm (#6068) 
* support saving into SmartEEPROM

Signed-off-by: Alexandre d Alton <alex@alexdalton.org>

* atsam: update smarteeprom implementation

- Use define for SmartEEPROM buffer address
- Check buffer overflow
- Do not perform operation when timeout occurs

Signed-off-by: Alexandre d'Alton <alex@alexdalton.org>

* return 0 instead of ff for invalid address or timeout

Signed-off-by: Alexandre d'Alton <alex@alexdalton.org>

* clang-format

* Add extra bounds checks

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.

Features

These features can be used in your keyboard.

  • Multi-layer Keymap - Multiple keyboard layouts with layer switching
  • Mouse key - Mouse control with keyboard
  • System Control Key - Power Down, Sleep, Wake Up and USB Remote Wake up
  • Media Control Key - Volume Down/Up, Mute, Next/Prev track, Play, Stop and etc
  • USB NKRO - 248 keys(+ 8 modifiers) simultaneously
  • PS/2 mouse support - PS/2 mouse(TrackPoint) as composite device
  • Keyboard protocols - PS/2, ADB, M0110, Sun and other old keyboard protocols
  • User Function - Customizable function of key with writing code
  • Macro - Very primitive at this time
  • Keyboard Tricks - Oneshot modifier and modifier with tapping feature
  • Debug Console - Messages for debug and interaction with firmware
  • Virtual DIP Switch - Configurations stored EEPROM(Boot Magic)
  • Locking CapsLock - Mechanical switch support for CapsLock
  • Breathing Sleep LED - Sleep indicator with charm during USB suspend
  • Backlight - Control backlight levels

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.
