Splits up ps2avrGB boards into their own folders (#2014)
* move underglow led count from parent to child * Added pearl support * Added personal keymap for pearl * start splitting up ps2avrGB boards * clean up ps2avrgb boards * Move keycodes to their own section * Clarify `KC_PWR` vs `KC_POWER`. Fixes #1994. * Cleaned uppersonal userspace and keymaps (#1998) * Cleanup of keymaps * Remove Tap Dance from Orthodox keymap * Cleaned up userspace and keymaps * Added sample (template)userspace files to my folder * Document the Teensy hardware reset problem * add mfluid keymap to atreus62 * Update hand_wire.md Change "Resin" to "Rosin" * Add keyboard: mt40 (#2001) * add keyboard: chinese planck clone * rename chinese_planck to mt40 * add image for the mt40 board * lets_split: Fix matrix_init for ROW2COL Signed-off-by: Marian Rusu <rusumarian91@gmail.com> * Add Keymap for Whitefox Truefox layout * Add keyboard: ACR60 (#1999) * base acr60 keyboard folder created * mitch acr60 keymap updates, documentation * latest keymap updates * slight modifications to layer switching * Changes to Atreus and Ergodox EZ Dvorak 42key layout (#1997) * importing 42 key dvorak layout * added comment for build instructions * adding atreus dvorak 42 key layout * added readme * add readme * build instructions * additional MEH shortcuts * added shifted symbols on symbols layer * working extra symbols on COMBINED layer * bring atreus layout inline with the ergodox one * add necessary macros * working ls macro * added more shell macros * added screen rename / screen number macros * add ctrl-a key in shell-nav to use screen more easily * added shell screen layer * assign screen switching macros to screen layer * define all screen switching macros * more screen-related shortcuts added on shell screen layer * change shell nav bottom right row to match base layer (backspace / delete) * remove some mappings on SHELL_NAV layer as they are now in the screen layer * added more screen macros * changes to COMBINED layer (pipe on the right) and modified shell nav * moved pipe/backslash to then right * documented SHELL_SCREEN layer * put backspace/delete on SHELL_NAV layer * add an explicit lisence file for github to pickup * Updated keymaps to allow base layer alternation for QWERTY, Colemak & Dvorak (#1962) * First commit of the Terminus_Mini firmware and the DivergeJM version of the Nyquist firmware * Fix terminus_mini & nyquist/DivergeJM readme files Previously an outdated copy of the default readme. Updated to match the Nyquist/DivergeJM format (DivergeJM is a split 5x12 implementation of the terminus_mini layout) * Update makefiles to rules.mk Renamed both Makefiles to rules.mk, removed references to makefiles * Updated rules.mk Inadvertantly removed important code from the rules.mk in previous commit. This has been restored. Also disabled Tap_Dance in both rules.mk files * Moved terminus_mini to handwired Realised that existing directory was not appropriate for the terminus_mini project, moved to handwired. * New Frosty Flake layout for QFR TKL Added a TKL layout for the Frosty Flake with a navigation cluster on LOWER under the left hand and a similarly functioning MOUSE layer that includes mouse navigation functionality. * README fix & keymap update for 3 keyboards Fixed the markdown for the handwired/terminus_mini:default, Nyqyist:DivergeJM & frosty_flake:QFR_JM. Added TAPPING_TERM = 150 to config.h for all keyboards Switched LT(LOWER) and LAlt on the mod row for ortholinear boards. * Update readme for QFR_JM to include make instructions * Revert "Merge branch 'master' of https://github.com/mogranjm/qmk_firmware" This reverts commit a45f264ada09acc14fb85390407bc7ff5bb021e3, reversing changes made to 62349c33410671a33d4041d50cf27de1d6bdd9cf. * Revert "Revert "Merge branch 'master' of https://github.com/mogranjm/qmk_firmware"" This reverts commit eae54fb3be2c60dffd704261f84bab98c9e06f93. * Added QWERTY support to the QFR_JM Implemented variable default base layer from the Planck default keymap. * Update README to reflect QWERTY support * Nyquist:DivergeJM - Update RESET location Add a reset button to both hands, accessible when halves are disconnected. * Typo fix * Update DivergeJM Switched master to Left hand, Moved Reset key to a different location * Added macros to send R pointer & dplyr pipe Macros added as a string of keypresses, couldn't figure out how to get SEND_STRING to work. * Added ADJUST -> QWERTY, DVORAK, COLEMAK Re-implemented update_tri_layer fuctionality to reset base layer for Terminus_Mini & DivergeJM Nyquist keymaps to QWERTY, DVORAK or COLEMAK via the ADJUST layer. Updated ReadMe files accordingly. * Fix base layout diagram for Terminus_Mini Remove split from diagram * Changed the R operators to SEND_STRING, rather than keypress macros * Added Dvorak to the QFR_JM keymap * fixed duplicate row in Nyquist keymap * Fix readme - LAlt location on mouse layer * Set EE_HANDS to allow either Nyquist hand to work as master. * Update R operator strings, clean up layering for terminus_mini, QFR_JM and DivergeJM "<-" to " <- " "%>%" to " %>% " Also played around with the layering, removed unnecessary TAP_TOGGLE for LOWER and shuffled FUNCTION and MOUSE momentary actions to reflect layer order. * Update bottom alpha row to output symbols on LOWER This row now outputs the following (z -> /) when in the LOWER layer: <- %>% { [ ` | ] } . / * Updated readme files for QFR_JM, terminus_mini & DivergeJM QFR_JM readme reflects correct LOWER bottom row symbol output, terminus_mini & DivergeJM reflect correct command line make instructions. * Add media keys to QFR_JM LOWER - Replicate QFR default functionality * Fix issue with Mouse layering Stuck on mouse layer because the wrong macro was assigned to the 'exit layer' key. Reassigned that key. * Changed " <- " to "<- " for QFR_JM, terminus_mini & DivergeJM * Add "KC_MAKE" to userspace example * QMK DFU bootloader generation (#2009) * adds :bootloader target * update planck and preonic revisions * remove references to .h files for planck * update preonic keymap * only add keyboard.h files that exist * add production target * hook things up with the new lufa variables * update rules for planck/preonic * back backlight key turn of status led when pressed * add manufacturer/product strings to bootloader * fix push script * Added support for let's split kailh socket version (#2010) * Added support for socket version of the let's split * renamed files * socket-version-works * fix up lets_split keymaps * fix up lets_split keymaps * shrink preonic by a bit * fix lets_split keyboards * update travis script * update travis script * update version silencing

+wire the lines to any other port, as long as D+ is also wired to INT0 (or any
+other hardware interrupt, as long as it is the highest level interrupt, see
+section at the end of this file).

+ * Descriptor handling is configured through the descriptor's properties. If

+ * Possible properties are:
+ * + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched

+ * in static memory is in RAM, not in flash memory.
+ * + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),

+ * found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):

+ * char usbDescriptorConfiguration[];
+ * char usbDescriptorHidReport[];

+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
