* LED driver update addressing PR #3871
Update sync between IS31FL3733 drivers is causing varying behavior in keyboards including brightness mismatch and slight flicker at very low rgb values. Visually, disabling sync is not noticeable. Ref PR #3871 by guarnacciaa.
Appearenly, teensy controllers have some issues with waking up. If the rgblight is called "too soon", it will cause the controller to lock up, intermittently. Adding a 10 ms
delay seems to fix this issue, as it lets it have enough time to handle things properly.
This has been tested extensively on my Ergodox EZ, and can be seen in the @drashna userspace, under the "suspend_wakeup_init_user" function.
Added support to enter bootloader from software (bootloader version must be newer than "v2.18Jun 22 2018 17:28:08" until workaround for older is created).
Updated CTRL and ALT keymaps for entering bootloader with Fn+b held for >500ms.
Added basic MacOS keymap for ALT.
USB sleep LED indicator now turns off after 1 second.
Slowed down debug LED code printing.
- Added support for NO_USB_STARTUP_CHECK. This allows the keyboard do function and not get stuck in a SUSPENDED state loop in case of no USB connection.
- Added support for WAIT_FOR_USB. In LUFA no keyboard has this flag enable therefor no keyboard waits for usb to be active.
- Added documentation for both configuration flags as they were missing.
Renamed keyboard alt67 to alt and adjusted necessary files where alt67 appeared.
CTRL keymap fixed enum structure name.
usb2422 removed stray define no longer used.
* STM32 EEPROM Emulation

- Remapped EEPROM memory map for 16 byte blocks (as is with STM32f3xx MCUs).
- Added EEPROM initialization in main.c of Chibios.
- Added EEPROM format to clear the emulated pages when EEPROM is marked as invalid.

* Fix non-feature file changes
* Add documentation
* Re-add matrix init docs
* add rgblight code to example
* Remove keyboard init stuff for separate PR
* And and fix _noeeprom functions to many of the RGB Underglow functions
* Many functions are unnecessarily calling the eeprom write code. The toggle/enable is command is especially guilty of this, as it writes to EEPROM 3 times. But rgb mode writes twice, every time it's called. And init resets the rgb eeprom range and then writes back to it twice!
* Fixed the rgblight_sethsv_noeeprom to work as expected, by moving a lot of the code to a helper function.
* Added a noeeprom function for mode, enable, disable, and toggle functions. (didn't bother for increase/decrease stuff, and didn't add new keycodes)
* Add to predefined colors list
* Add new functions to manual/docs
* Update RGB Sleep feature to use _noeeprom
Because that's exactly what it should be doing, actually!
* Fix dead link to USB keycodes doc
Link was dead and the fresher version I could find on usb.org is still older than this one.
Thus, WaybackMachine seems the best option.
* Fix dead link to USB keycodes doc, with 2 options
Give the WaybackMachine link (fresher and for reference of the content of the original link) and the usb.org one (older)
Many a times one would want to use multiple modifiers with the same key,
preferably without having to hold anything, like `Ctrl+Shift+C` or
`Ctrl+Shift+V` to copy/paste in GNOME Terminal. To make this possible, we need
to be able to chain one-shot modifiers, so that we can have multiple of them
active at the same time.
The easiest way to accomplish this is that whenever we activate a one-shot
modifier, we apply it on top of the existing set, instead of re-setting the
state. When deactivating, either due to an interrupt, or due to a timeout, we
deactivate all oneshots anyway, so the clearing part is covered. When we turn
the one-shot modifier into a toggle, that will also clear all one-shot modifiers
first, so we covered that case too.
Fixes#2796, #1580, and #856.

This is an inelegant hack for #2522 but makes things work. Basically we give `action.c` a chance to handle the hold event early so that we can swap the keyboard for later keys. Later, to allow the hold to happen again quickly we nuke the key record so that tapping is reset. I tried to find a cleaner way, honestly.

This is particularly relevant for, e.g., the ergodox EZ and
other keyboards with slow scan rates. Without changing the API or
behavior of individual process_record() calls, we allow a
configuration flag to make multiple calls in a single scan.
This will probably have miniscule effects on non-steno users,
and it's not enabled by default for any keyboards. Added note
about it to ergodox README.

Updated MiniDox split_util.h and eeprom files to reflect this change.
I recommend adding this to any split board that used these files, my changes will not effect them currently.
This protocol breaks out "duplicate" keys into their own entry in the packet so that more complicated logic can be done on the software side, including support for additional languages and alternative theories.
This introduces a grep dependency, which I believe we didn't have
before, but it should be available and installed by default on all the
supported systems.

The oneshot cancellation code do not depend on the
action_tapping_process and since process_record get called via the
action_tapping_process logic moved the oneshot cancellation code into
the action_exec function just before the action_tapping_process call
A macro key can now be easily set to act as a modifier on hold, and
press a shifted key when tapped. Or to switch layers when held, and
again press a shifted key when tapped.
Various other helper defines have been created which send macros when
the key is pressed, released and tapped, cleaning up the
action_get_macro function inside keymap definitions.
The layer switching macros require a GCC extension - 'compound
statements enclosed within parentheses'. The use of this extension is
already present within the macro subsystem of this project, so its use
in this commit should not cause any additional issues.
MACRO_NONE had to be cast to a (macro_t*) to suppress compiler
warnings within some tapping macros.
Since we can't read the real_mods and oneshot_mods static variable
directly within the update_user_visualizer_state
function (Threading and serial link). We are know storing the mods
states in the visualizer_keyboard_status_t structure. We can now
display the status of the modifier keys on the LCD display.
After setting a ONESHOT_TIMEOUT value, the oneshot layer state would
not expire without an event being triggered (key pressed). The reason
was that in the process_record function we would return priort to
execute the process_action function if it detected a NOEVENT cycle. The
process_action contained the codes to timeout the oneshot layer state.
The codes to clear the oneshot layer state have been move just in
front of where we check for the NOEVENT cycle in the process_record
function.
Fix memory leaks by using stack instead of malloc
Reduce memory usage by having less temporary bufffers
Remove warnings by adding includes
Decrease code size by 608 bytes (mostly due to not linking malloc)
More robust handling of buffer overflows
There are a lot of PS/2 commands, some are vendor/device specific, so we
provide a weak ps2_mouse_init_user() to be implemented in each keyboard
that need it.
There are now 3 potential locations to send HID reports:
1. USB
2. The bluefruit easy key
3. Adafruit BLE
Generally speaking, if USB is connected then we should prefer to
send the reports there; it is generally the best channel for this.
The bluefruit module has no feedback about bluetooth connectivity
so the code must speculatively send reports over both USB and bluetooth.
The BLE module has connectivity feedback. In general we want to
prefer to send HID reports over USB while connected there, even
if BLE is connected. Except that it is convenient to force them
over BLE while testing the implementation.
This policy has been extracted out into a where_to_send function
which returns a bitmask of which of the channels should be used.
This implements some helper functions that allow sending key reports
to an SPI based Bluetooth Low Energy module, such as the Adafruit
Feather 32u4 Bluefruit LE.
There is some plumbing required in lufa.c to enable this; that
is in a follow-on commit.
Adopt the macros for saving/restoring the interrupt state
that are provided by the avr gcc environment.
Removing intialization of the timer value; this shaves off
a few bytes because globals are default initialized to zero.
User print disables the normal print messages in the body of QMK/TMK
code and is meant as a lightweight alternative to NOPRINT. Use it when
you only want to do a spot of debugging but lack flash resources for
allowing all of the codebase to print (and store their wasteful
strings).
