From f30f12ec8122b7c025ff83c5e38e171c4107052b Mon Sep 17 00:00:00 2001 From: Joe Wasson Date: Wed, 26 Jul 2017 21:51:41 -0700 Subject: [PATCH] Add support for GeminiPR steno protocol. 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. --- keyboards/planck/keymaps/steno/Makefile | 4 +- keyboards/planck/keymaps/steno/keymap.c | 5 +- quantum/keymap_extras/keymap_steno.h | 9 +- quantum/process_keycode/process_steno.c | 115 +++++++++++++++++++----- quantum/process_keycode/process_steno.h | 4 + quantum/quantum_keycodes.h | 2 + tmk_core/common/eeconfig.c | 3 + tmk_core/common/eeconfig.h | 1 + tmk_core/common/keyboard.c | 6 ++ 9 files changed, 121 insertions(+), 28 deletions(-) diff --git a/keyboards/planck/keymaps/steno/Makefile b/keyboards/planck/keymaps/steno/Makefile index 3ed9d2db45f..874154af630 100644 --- a/keyboards/planck/keymaps/steno/Makefile +++ b/keyboards/planck/keymaps/steno/Makefile @@ -3,5 +3,5 @@ ifndef QUANTUM_DIR endif MOUSEKEY_ENABLE = no # Mouse keys(+4700) -STENO_ENABLE = yes # Enable TX Bolt protocol for Stenography, requires VIRTSER and may not work with mouse keys - +STENO_ENABLE = yes # Additional protocols for Stenography(+1700), requires VIRTSER +AUDIO_ENABLE = no # Audio output on port C6 diff --git a/keyboards/planck/keymaps/steno/keymap.c b/keyboards/planck/keymaps/steno/keymap.c index b4e30169fb3..38540a26137 100644 --- a/keyboards/planck/keymaps/steno/keymap.c +++ b/keyboards/planck/keymaps/steno/keymap.c @@ -41,6 +41,9 @@ enum planck_keycodes { EXT_PLV }; +#define ST_BOLT QK_STENO_BOLT +#define ST_GEM QK_STENO_GEMINI + const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = { /* Qwerty @@ -166,7 +169,7 @@ const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = { [_ADJUST] = { {_______, RESET, _______, _______, _______, _______, _______, _______, _______, _______, _______, KC_DEL }, {_______, _______, MU_MOD, AU_ON, AU_OFF, AG_NORM, AG_SWAP, QWERTY, COLEMAK, DVORAK, PLOVER, _______}, - {_______, MUV_DE, MUV_IN, MU_ON, MU_OFF, MI_ON, MI_OFF, _______, _______, _______, _______, _______}, + {_______, MUV_DE, MUV_IN, MU_ON, MU_OFF, MI_ON, MI_OFF, _______, _______, _______, ST_BOLT, ST_GEM}, {_______, _______, _______, _______, _______, _______, _______, _______, _______, _______, _______, _______} } diff --git a/quantum/keymap_extras/keymap_steno.h b/quantum/keymap_extras/keymap_steno.h index 4eb1c7477ad..4ce91cc1352 100644 --- a/quantum/keymap_extras/keymap_steno.h +++ b/quantum/keymap_extras/keymap_steno.h @@ -18,8 +18,12 @@ #include "keymap.h" +// List of keycodes for the steno keyboard.
