[Keyboard] gBoards GergoPlex (#13027)
* Moved gergoplex to seperate PR
* vendor + cformat
* Update keyboards/gboards/k/gergoplex/matrix.c
Co-Authored-By: Drashna Jaelre <drashna@live.com>
* lifiting keyboards up
* Update readme.md
* Update keyboards/gboards/gergoplex/config.h
Co-authored-by: Drashna Jaelre <drashna@live.com>
* remove English dicts
* cformatted
* Prettify keymap
* Remove via keymaps
Via doesn't support chords/combos, and this makes the keymap on such a
small keyboard quite uncomfortable and incomplete.
* Address QMK pull code review notes
* Cleanup (tabs, excessive comments)
* Fix keymap typos
* Use enum to define layers
* Multiple changes
- got rid of LAYOUT_kc in favour of LAYOUT_split_3x5_3
- fixed matrix custom C code to build with updated external dependencies (gcc)
- fixed used combo docs
keyboards/gboards/gergoplex/matrix.c:189:9: error: implicit declaration of function 'phex' [-Werror=implicit-function-declaration]
phex(row);
^~~~
keyboards/gboards/gergoplex/matrix.c:191:9: error: implicit declaration of function 'pbin_reverse16'; did you mean 'print_bin_reverse16'? [-Werror=implicit-function-declaration]
pbin_reverse16(matrix_get_row(row));
* Remove apparently redundant macros
* Replace direct pin control with IO functions
* config mouse enable and combo delay fix
The default delay is 200:
#define COMBO_TERM 200
how long for the Combo keys to be detected. Defaults to TAPPING_TERM if not defined.
tmk_core/common/action_tapping.h|22| 13:# define TAPPING_TERM 200
* Remove redundant defines
* Unambiguously refer to the Special layer
* Fix formatting
* gboards/gergoplex set IGNORE_MOD_TAP_INTERRUPT
This solves my issue was with KC_CTL_A working correctly and it was set in @germ's repo

https://beta.docs.qmk.fm/using-qmk/software-features/tap_hold#ignore-mod-tap-interrupt
* Name change
See commit 581368596ed
* Wording change
* Update keyboards/gboards/gergoplex/keymaps/default/keymap.c
Co-authored-by: Drashna Jaelre <drashna@live.com>
* Add copyright headers
* Fix debounce type
| avr-gcc: error: .build/obj_gboards_gergoplex_default/quantum/debounce/eager_pr.o: No such file or directory
* Implement colemak-dhm keymap
