BlueMicro nRF52: Tap/Hold for Layers

Tap for single key, hold to access layer

 1. Add new folder under Keymaps "tapholdlayer"

2. Copy keymap.cpp and keymap.h (from spacecadet)

3. Create a new set of keymap as format below. layer1, tap, hold...change accordingly.

void setupKeymap() {

    uint32_t press[MATRIX_ROWS][MATRIX_COLS] =
        KEYMAP( \
  KC_GRAVE,KC_1,    KC_2,    KC_3,    KC_4,   KC_5, KC_UNDS,  \

);


uint32_t layer1[MATRIX_ROWS][MATRIX_COLS] =
        KEYMAP( \

uint32_t tap[MATRIX_ROWS][MATRIX_COLS] =

); 

uint32_t hold[MATRIX_ROWS][MATRIX_COLS] =
        KEYMAP( \

); 

uint32_t singletap[MATRIX_ROWS][MATRIX_COLS] =
        KEYMAP( \

); 

 

 next part is:

do note the _L1/2/3/0, it is defined in keymap.h, eg. #define _QWERTY 0

4. change the following lines for new layers added for mod/tap

      /*
     * add the other layers on the regular presses.
     */
    for (int row = 0; row < MATRIX_ROWS; ++row)
    {
        for (int col = 0; col < MATRIX_COLS; ++col)
        {
            //Method::Press Standard keypress
			//Method::MT_TAP This key is sent once when the key is tapped.
			//Method::MT_HOLD This key is sent once when the key is held. 
			//Method::DT_TAP This key is sent once when the key is tapped. 
			//Method::DT_DOUBLETAP This key is sent once when the key is tapped twice. 
			matrix[row][col].addActivation(_QWERTY, Method::MT_TAP, tap[row][col]);
			matrix[row][col].addActivation(_QWERTY, Method::MT_HOLD, hold[row][col]);
			matrix[row][col].addActivation(_L1, Method::PRESS, layer1[row][col]);
        }
    }
