# Terrazzo
|
|
|
|
|
|
|
|
Terrazzo is a 40% pro micro keyboard kit with a fun, hot-swapable LED module. It is offered in both staggered and ortholinear variations, each with multiple layout options. A left hand macro column has 4 positions for switches or rotary encoders.
|
|
|
|
Extended layout options and multiple encoder support will require use of an Elite-C controller. Key switch support is MX soldered only.
|
|
|
|
* Keyboard Maintainer: MsMustard, [Anne Demey](https://github.com/ademey)
|
|
* Hardware Supported: Terrazzo v1 & v2 PCB in staggered and ortholinear
|
|
|
|
Make example for this keyboard (after setting up your build environment):
|
|
|
|
- `make terrazzo:default` Split spacebar staggered layout

## Custom Keycodes
|
|
|
|
Terrazzo has several custom keycodes for LED control.
|
|
|
|
| Key | Description |
|
|
|-----|-------------|
|
|
| `TZ_NXT` | Next Animation |
|
|
| `TZ_PRV` | Previous Animation |
|
|
| `TZ_OFF` | LED Off |
|
|
|
|
## LED Animations
|
|
|
|
LED animations for Terrazzo are reactive to keyboard input. Each key press or encoder turn increments an internal counter, looping through the number of individual LEDs.
|
|
|
|
This counter (`terrazzo_led_index`) is used as a seed for the animation functions, along with a boolean indicating the direction. Turning the encoder counter-clockwise, or pressing backspace will decrement the counter, allowing for animations to reverse or display alternative frames.
|
|
|
|
The current animations are:
|
|
|
|
- DINO: It's like your internet went out
|
|
- DOT: Just a single led at a time, for debugging
|
|
- HEART: Love you too
|
|
- OUTRUN: Driving into the sunset
|
|
- PAC_DUDE: Vintage arcade fun
|
|
- STRIPES: Just a nice gradient
|
|
- WPM_CHART: 2 digit readout with lights indicating speed, each pixel = 2 wpm
|
|
|
|
Not all animations are enabled by default. You can enable or disable animations in the `config.h` file to limit firmware size.
|
|
|
|
```
|
|
// #define DISABLE_TERRAZZO_EFFECT_STRIPES
|
|
// #define DISABLE_TERRAZZO_EFFECT_DINO
|
|
// #define DISABLE_TERRAZZO_EFFECT_OUTRUN
|
|
#define DISABLE_TERRAZZO_EFFECT_PAC_DUDE
|
|
#define DISABLE_TERRAZZO_EFFECT_HEART
|
|
// #define DISABLE_TERRAZZO_EFFECT_WPM_CHART
|
|
#define DISABLE_TERRAZZO_EFFECT_DOT
|
|
```
|
|
|
|
## Microcontroller Support
|
|
|
|
Terrazzo is designed for use with a Pro Micro (or compatible, like Bit-C), or an Elite-C. The extra pinouts of an Elite-C are required for the ortho MIT and ALL layouts and multiple encoders. By default the firmware is set up for an Elite-C. For a Pro Micro some changes to `config.h` are needed.
|
|
|
|
Change number of rows from 9 to 8.
|
|
```
|
|
#define MATRIX_ROWS 8
|
|
```
|
|
|
|
Change pinouts, Pro Micro does not have the "F0" pin.
|
|
```
|
|
#define MATRIX_ROW_PINS { D2, D7, E6, B4, B5, B6, B2, B3 }
|
|
```
|
|
|
|
Set encoder to just top or bottom position.
|
|
```
|
|
#define ENCODER_A_PINS { C6 }
|
|
#define ENCODER_B_PINS { D4 }
|
|
```
|
|
|
|
## Encoder Setup
|
|
|
|
Terrazzo has 4 positions for encoders in the left-hand column. Up to 3 may be used at a time, but this requires the extra pins of an Elite-C. Please refer to `config.h` for examples of pin configurations.
|
|
|
|
The default keymaps are setup for one encoder. Encoders can change behavior based on the current layer. Here, on the "NAV" layer, the encoder changes volume instead of scrolling.
|
|
|
|
```c
|
|
bool encoder_update_user(uint8_t index, bool clockwise) {
|
|
terrazzo_scroll_pixel(clockwise);
|
|
switch(get_highest_layer(layer_state)) {
|
|
case _NAV:
|
|
// Change volume when on nav layer
|
|
clockwise ? tap_code(KC_AUDIO_VOL_UP) : tap_code(KC_AUDIO_VOL_DOWN);
|
|
break;
|
|
default:
|
|
// Default encoder behavior of Page Up and Down
|
|
clockwise ? tap_code(KC_PGDN) : tap_code(KC_PGUP);
|
|
break;
|
|
}
|
|
return true;
|
|
}
|
|
```
|
|
|
|
If using multiple encoders, the `index` param can be used to distingish which is providing input.
|
|
|
|
```c
|
|
bool encoder_update_user(uint8_t index, bool clockwise) {
|
|
terrazzo_scroll_pixel(clockwise);
|
|
switch(index) {
|
|
case 0:
|
|
clockwise ? tap_code(KC_PGDN) : tap_code(KC_PGUP);
|
|
break;
|
|
case 1:
|
|
clockwise ? tap_code(KC_AUDIO_VOL_UP) : tap_code(KC_AUDIO_VOL_DOWN);
|
|
break;
|
|
}
|
|
return true;
|
|
}
|
|
```
