Two for VCC and GND and one + for serial communication. +* Optional support for I2C connection between the two halves if for some + reason you require a faster connection between the two halves. Note this + requires an extra wire between halves and pull-up resistors on the data lines. + +Required Hardware +----------------- + +Apart from diodes and key switches for the keyboard matrix in each half, you +will need: + +* 2 Arduino Pro Micro's. You can find theses on aliexpress for ≈3.50USD each. +* 2 TRS sockets +* 1 TRS cable. + +Alternatively, you can use any sort of cable and socket that has at least 3 +wires. If you want to use I2C to communicate between halves, you will need a +cable with at least 4 wires and 2x 4.7kΩ pull-up resistors + + +Wiring +------ + +The 3 wires of the TRS cable need to connect GND, VCC, and digital pin 3 (i.e. +`PD0` on the ATmega32u4) between the two Pro Micros. + +Then wire your key matrix to any of the remaining 17 IO pins of the pro micro +and modify the `MATRIX_COL_PINS` and `MATRIX_ROW_PINS` in `config.h` accordingly. + +The wiring for serial: + +![serial wiring](imgs/split-keyboard-serial-schematic.png) + +The wiring for i2c: + +![i2c wiring](imgs/split-keyboard-i2c-schematic.png) + +The pull-up resistors may be placed on either half. It is also possible +to use 4 resistors and have the pull-ups in both halves, but this is +unnecessary in simple use cases. + +Notes on Software Configuration +------------------------------- + +Configuring the firmware is similar to any other TMK project. One thing +to note is that `MATIX_ROWS` in `config.h` is the total number of rows between +the two halves, i.e. if your split keyboard has 4 rows in each half, then +`MATRIX_ROWS=8`. + +Also the current implementation assumes a maximum of 8 columns, but it would +not be very difficult to adapt it to support more if required. + + +Flashing +-------- + +Before you go to flash the program memory for the first time, you will need to +EEPROM for the left and right halves. The EEPROM is used to store whether the +half is left handed or right handed. This makes it so that the same firmware +file will run on both hands instead of having to flash left and right handed +versions of the firmware to each half. To flash the EEPROM file for the left +half run: +``` +make eeprom-left +``` +and similarly for right half +``` +make eeprom-right +``` + +After you have flashed the EEPROM for the first time, you then need to program +the flash memory: +``` +make program +``` +Note that you need to program both halves, but you have the option of using +different keymaps for each half. You could program the left half with a QWERTY +layout and the right half with a Colemak layout. Then if you connect the left +half to a computer by USB the keyboard will use QWERTY and Colemak when the +right half is connected. + + diff --git a/keyboard/foobar/actionmap_common.h b/keyboard/foobar/actionmap_common.h new file mode 100644 index 00000000..013f3adc --- /dev/null +++ b/keyboard/foobar/actionmap_common.h @@ -0,0 +1,22 @@ +#ifndef ACTIONMAP_COMMON_H +#define ACTIONMAP_COMMON_H + +#define ACTIONMAP( \ + K00, K01, K02, K03, K04, \ + K10, K11, K12, K13, K14, \ + K20, K21, K22, K23, K24, \ +\ + K30, K31, K32, K33, K34, \ + K40, K41, K42, K43, K44, \ + K50, K51, K52, K53, K54 \ +) { \ + { AC_##K00, AC_##K01, AC_##K02, AC_##K03, AC_##K04 }, \ + { AC_##K10, AC_##K11, AC_##K12, AC_##K13, AC_##K14 }, \ + { AC_##K20, AC_##K21, AC_##K22, AC_##K23, AC_##K24 }, \ +\ + { AC_##K34, AC_##K33, AC_##K32, AC_##K31, AC_##K30 }, \ + { AC_##K44, AC_##K43, AC_##K42, AC_##K41, AC_##K40 }, \ + { AC_##K54, AC_##K53, AC_##K52, AC_##K51, AC_##K50 } \ +} + +#endif diff --git a/keyboard/foobar/actionmap_plain.c b/keyboard/foobar/actionmap_plain.c new file mode 100644 index 00000000..c07d78a9 --- /dev/null +++ b/keyboard/foobar/actionmap_plain.c @@ -0,0 +1,97 @@ +#include "actionmap.h" +#include "action_code.h" +#include "actionmap_common.h" + + +/* + * Actions + */ +#define AC_BLD ACTION_BACKLIGHT_DECREASE() +#define AC_BLI ACTION_BACKLIGHT_INCREASE() +#define AC_TL1 ACTION_LAYER_TAP_KEY(1, KC_SPACE) +#define AC_TL2 ACTION_LAYER_TAP_KEY(2, KC_BSPACE) +#define AC_TL3 ACTION_LAYER_TAP_KEY(3, KC_C) +#define AC_TL4 ACTION_LAYER_TAP_KEY(4, KC_V) +#define AC_TL5 ACTION_LAYER_TAP_KEY(5, KC_B) +#define AC_TM1 ACTION_MODS_TAP_KEY(MOD_RSFT, KC_ENT) +#define AC_TM2 ACTION_MODS_TAP_KEY(MOD_LCTL, KC_Z) +#define AC_TM3 ACTION_MODS_TAP_KEY(MOD_LALT, KC_X) +#define AC_TM4 ACTION_MODS_TAP_KEY(MOD_RALT, KC_N) +#define AC_TM5 ACTION_MODS_TAP_KEY(MOD_RCTL, KC_M) +#define AC_S01 ACTION_MODS_KEY(MOD_LSFT, KC_1) +#define AC_S02 ACTION_MODS_KEY(MOD_LSFT, KC_2) +#define AC_S03 ACTION_MODS_KEY(MOD_LSFT, KC_3) +#define AC_S04 ACTION_MODS_KEY(MOD_LSFT, KC_4) +#define AC_S05 ACTION_MODS_KEY(MOD_LSFT, KC_5) +#define AC_S06 ACTION_MODS_KEY(MOD_LSFT, KC_6) +#define AC_S07 ACTION_MODS_KEY(MOD_LSFT, KC_7) +#define AC_S08 ACTION_MODS_KEY(MOD_LSFT, KC_8) +#define AC_S09 ACTION_MODS_KEY(MOD_LSFT, KC_9) +#define AC_S10 ACTION_MODS_KEY(MOD_LSFT, KC_0) +#define AC_S11 ACTION_MODS_KEY(MOD_LSFT, KC_MINS) +#define AC_S12 ACTION_MODS_KEY(MOD_LSFT, KC_EQL) +#define AC_S13 ACTION_MODS_KEY(MOD_LSFT, KC_LBRC) +#define AC_S14 ACTION_MODS_KEY(MOD_LSFT, KC_RBRC) +#define AC_S15 ACTION_MODS_KEY(MOD_LSFT, KC_BSLS) +#define AC_S16 ACTION_MODS_KEY(MOD_LSFT, KC_COMM) +#define AC_S17 ACTION_MODS_KEY(MOD_LSFT, KC_DOT) +#define AC_S18 ACTION_MODS_KEY(MOD_LSFT, KC_SLSH) +#define AC_S19 ACTION_MODS_KEY(MOD_LSFT, KC_SCLN) +#define AC_S20 ACTION_MODS_KEY(MOD_LSFT, KC_QUOT) + +const action_t PROGMEM actionmaps[][MATRIX_ROWS][MATRIX_COLS] = { + [0] = ACTIONMAP( + Q, W, E, R, T, + A, S, D, F, G, + TM2, TM3, TL3, TL4, TL2, + + Y, U, I, O, P, + H, J, K, L, ESC, + TL1, TL5, TM4, TM5, TM1), + + [1] = ACTIONMAP( + 1, 2, 3, 4, 5, + F1, F2, F3, F4, F5, + TRNS, TRNS, TRNS, TRNS, DEL, + + 6, 7, 8, 9, 0, + F6, F7, F8, F9, F10, + TRNS, TRNS, TRNS, TRNS, TRNS), + + [2] = ACTIONMAP( + S01, S02, S03, S04, S05, + F11, F12, TRNS, TRNS, TRNS, + TRNS, TRNS, TRNS, TRNS, TRNS, + + S06, S07, S08, S09, S10, + TRNS, TRNS, TRNS, TRNS, GRV, + TRNS, TRNS, TRNS, TRNS, TRNS), + + [3] = ACTIONMAP( + TRNS, TRNS, TRNS, TRNS, TRNS, + TAB, TRNS, TRNS, TRNS, TRNS, + TRNS, TRNS, TRNS, TRNS, TRNS, + + MINS, EQL, LBRC, RBRC, BSLS, + COMM, DOT, SLSH, SCLN, QUOT, + TRNS, LEFT, DOWN, UP, RGHT), + + [4] = ACTIONMAP( + TRNS, TRNS, TRNS, TRNS, TRNS, + TAB, TRNS, TRNS, TRNS, TRNS, + TRNS, TRNS, TRNS, TRNS, TRNS, + + S11, S12, S13, S14, S15, + S16, S17, S18, S19, S20, + TRNS, HOME, PGDN, PGUP, END), + + [5] = ACTIONMAP( + CALC, WHOM, MAIL, MYCM, TRNS, + TRNS, TRNS, TRNS, TRNS, TRNS, + TRNS, TRNS, TRNS, TRNS, BTLD, + + TRNS, TRNS, TRNS, TRNS, PSCR, + TRNS, TRNS, TRNS, BLD, BLI, + TRNS, TRNS, TRNS, TRNS, TRNS), +}; + diff --git a/keyboard/foobar/config.h b/keyboard/foobar/config.h new file mode 100644 index 00000000..e104289a --- /dev/null +++ b/keyboard/foobar/config.h @@ -0,0 +1,113 @@ +/* +Copyright 2012 Jun Wako + +This program is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 2 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
