# Charybdis (3x5) default keymap
> :bulb: Have a look at the [`via` keymap](../via) for a more feature-rich layout.
The Charydbis (3x5) default keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap.
This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.

# Charybdis (3x5) `via` keymap
The Charydbis (3x5) `via` keymap is based on a QWERTY layout with [home row mods](https://precondition.github.io/home-row-mods) and [Miryoku-inspired layers](https://github.com/manna-harbour/miryoku), and some features and changes specific to the Charybdis.
This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.
This layout also supports VIA.
## Customizing the keymap
### Dynamic DPI scaling
Use the following keycodes to change the default DPI:
- `POINTER_DEFAULT_DPI_FORWARD`: increases the DPI; decreases when shifted;
- `POINTER_DEFAULT_DPI_REVERSE`: decreases the DPI; increases when shifted.
There's a maximum of 16 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
Use the following keycodes to change the sniping mode DPI:
- `POINTER_SNIPING_DPI_FORWARD`: increases the DPI; decreases when shifted;
- `POINTER_SNIPING_DPI_REVERSE`: decreases the DPI; increases when shifted.
There's a maximum of 4 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
### Drag-scroll
Use the `DRAGSCROLL_MODE` keycode to enable drag-scroll on hold. Use the `DRAGSCROLL_TOGGLE` keycode to enable/disable drag-scroll on key press.
### Sniping
Use the `SNIPING_MODE` keycode to enable sniping mode on hold. Use the `SNIPING_TOGGLE` keycode to enable/disable sniping mode on key press.
Change the value of `CHARYBDIS_AUTO_SNIPING_ON_LAYER` to automatically enable sniping mode on layer change. By default, sniping mode is enabled on the pointer layer:
```c
#define CHARYBDIS_AUTO_SNIPING_ON_LAYER LAYER_POINTER
```
### Auto pointer layer
The pointer layer can be automatically enabled when moving the trackball. To enable or disable this behavior, add or remove the following define:
```c
#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_ENABLE
```
By default, the layer is turned off 1 second after the last registered trackball movement:
```c
#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_TIMEOUT_MS 1000
```
The trigger sensibility can also be tuned. The lower the value, the more sensible the trigger:
```c
#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_THRESHOLD 8
```

# Charybdis (4x6) default keymap
> :bulb: Have a look at the [`via` keymap](../via) for a more feature-rich layout.
The Charydbis (4x6) default keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap.
This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.

# Charybdis (4x6) `via` keymap
The Charydbis (4x6) `via` keymap is inspired from the original [Dactyl Manuform](../../../../../handwired/dactyl_manuform) default keymap, with some features and changes specific to the Charybdis.
This layout supports RGB matrix. However, due to space constraints on the MCU, only a limited number of effect can be enabled at once. Look at the `config.h` file and enable your favorite effect.
## Customizing the keymap
### Dynamic DPI scaling
Use the following keycodes to change the default DPI:
- `POINTER_DEFAULT_DPI_FORWARD`: increases the DPI; decreases when shifted;
- `POINTER_DEFAULT_DPI_REVERSE`: decreases the DPI; increases when shifted.
There's a maximum of 16 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
Use the following keycodes to change the sniping mode DPI:
- `POINTER_SNIPING_DPI_FORWARD`: increases the DPI; decreases when shifted;
- `POINTER_SNIPING_DPI_REVERSE`: decreases the DPI; increases when shifted.
There's a maximum of 4 possible values for the sniping mode DPI. See the [Charybdis documentation](../../README.md) for more information.
### Drag-scroll
Use the `DRAGSCROLL_MODE` keycode to enable drag-scroll on hold. Use the `DRAGSCROLL_TOGGLE` keycode to enable/disable drag-scroll on key press.
### Sniping
Use the `SNIPING_MODE` keycode to enable sniping mode on hold. Use the `SNIPING_TOGGLE` keycode to enable/disable sniping mode on key press.
Change the value of `CHARYBDIS_AUTO_SNIPING_ON_LAYER` to automatically enable sniping mode on layer change. By default, sniping mode is enabled on the pointer layer:
```c
#define CHARYBDIS_AUTO_SNIPING_ON_LAYER LAYER_POINTER
```
### Auto pointer layer
The pointer layer can be automatically enabled when moving the trackball. To enable or disable this behavior, add or remove the following define:
```c
#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_ENABLE
```
By default, the layer is turned off 1 second after the last registered trackball movement:
```c
#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_TIMEOUT_MS 1000
```
The trigger sensibility can also be tuned. The lower the value, the more sensible the trigger:
```c
#define CHARYBDIS_AUTO_POINTER_LAYER_TRIGGER_THRESHOLD 8
```

# Charybdis (6x4, 5x3 "Nano")
An ergonomic keyboard with integrated trackball.
Engineered to be a full mouse replacement solution with high-quality, custom-developed components.
There are 6x4 and 5x3 "Nano" versions.
- Keyboard Maintainer: [Bastard Keyboards](https://github.com/Bastardkb)
- Hardware Supported: elite-C V4
- Hardware Availability: [Bastard Keyboards](https://bastardkb.com)
See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
Brand new to QMK? Start with the [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
Check out the [keyboard build guides](https://docs.bastardkb.com) for the Charybdis and other ergonomic keyboards.
## Building the firmware
### Charybdis (4x6)
The `default` keymap is inspired from the original [Dactyl Manuform](../../handwired/dactyl_manuform) layout.
```shell
qmk compile -kb bastardkb/charybdis/4x6 -km default
```
Check out the `via` layout if you're looking for VIA support:
```shell
qmk compile -kb bastardkb/charybdis/4x6 -km via
```
### Charybdis (3x5)
The `default` keymap is inspired from the original [Dactyl Manuform](../../handwired/dactyl_manuform) layout.
```shell
qmk compile -kb bastardkb/charybdis/3x5 -km default
```
Check out the `via` layout if you're looking for VIA support:
```shell
qmk compile -kb bastardkb/charybdis/3x5 -km via
```
## Customizing the firmware
### Dynamic DPI scaling
The pointer's DPI can be changed at runtime.
By default, the DPI is set to `400`. The Charybdis supports up to 16 different DPI values. By default, it cycles between `400` and `3400`, with a step of `200` (_ie._ `400`, `600`, `800`, …, `3400`).
Calling `charybdis_cycle_pointer_default_dpi(bool forward)` will cycle forward or backward the possible values.
Use `charybdis_cycle_pointer_default_dpi_noeeprom(bool forward)` to change the DPI value without persisting the change to EEPROM (_ie._ resetting the board will revert to the last saved value).
`charybdis_get_pointer_default_dpi()` returns the current DPI value.
This behavior can be further customized with the following defines:
```c
#define CHARYBDIS_MINIMUM_DEFAULT_DPI 400
#define CHARYBDIS_DEFAULT_DPI_CONFIG_STEP 200
```
### Drag-scroll
Drag-scroll enables scrolling with the trackball. When drag-scroll is enabled, the trackball's `x` and `y` movements are converted into `h` (horizontal) and `v` (vertical) movement, effectively sending scroll instructions to the host system.
Call `charybdis_set_pointer_dragscroll_enabled(bool enable)` to enable/disable drag-scroll.
`charybdis_get_pointer_dragscroll_enabled()` returns whether sniping mode is currently enabled.
To invert the horizontal scrolling direction, define `CHARYBDIS_DRAGSCROLL_REVERSE_X`:
```c
#define CHARYBDIS_DRAGSCROLL_REVERSE_X
```
To invert the vertical scrolling direction (_ie._ mimic macOS "natural" scroll direction), define `CHARYBDIS_DRAGSCROLL_REVERSE_Y`:
```c
#define CHARYBDIS_DRAGSCROLL_REVERSE_Y
```
This only affects the vertical scroll direction.
### Sniping mode
Sniping mode slows down the pointer for more precise gestures. It is useful when combined with a higher default DPI.
Call `charybdis_set_pointer_sniping_enabled(bool enable)` to enable/disable sniping mode.
`charybdis_get_pointer_sniping_enabled()` returns whether sniping mode is currently enabled.
Like the default pointer's DPI, the sniper mode DPI can be changed at runtime.
By default, sniping mode lowers the DPI to `200`. This can be changed at runtime: the Charybdis supports up to 4 different DPI values for sniping mode. By default, it cycles between `200`, `300`, `400` and `500`.
Calling `charybdis_cycle_pointer_sniping_dpi(bool forward)` will cycle forward or backward the possible values.
Use `charybdis_cycle_pointer_sniping_dpi_noeeprom(bool forward)` to change the sniping mode DPI value without persisting the change to EEPROM (_ie._ resetting the board will revert to the last saved value).
`charybdis_get_pointer_sniping_dpi()` returns the current sniping mode DPI value.
This behavior can be further customized with the following defines:
```c
#define CHARYBDIS_MINIMUM_SNIPING_DPI 200
#define CHARYBDIS_SNIPING_DPI_CONFIG_STEP 100
```
### Acceleration
By default, the pointer's movements are linear. To enable acceleration, add the following define:
```c
#define CHARYBDIS_POINTER_ACCELERATION_ENABLE
```
The acceleration factor can be further tune _via_ the `CHARYBDIS_POINTER_ACCELERATION_FACTOR`:
```c
#define CHARYBDIS_POINTER_ACCELERATION_FACTOR 24
```
### Custom keycodes
The Charybdis firmware defines a number of keycodes to leverage its features, namely:
```
#ifndef NO_CHARYBDIS_KEYCODES
enum charybdis_keycodes {
POINTER_DEFAULT_DPI_FORWARD = SAFE_RANGE,
POINTER_DEFAULT_DPI_REVERSE,
POINTER_SNIPING_DPI_FORWARD,
POINTER_SNIPING_DPI_REVERSE,
SNIPING_MODE,
SNIPING_MODE_TOGGLE,
DRAGSCROLL_MODE,
DRAGSCROLL_MODE_TOGGLE,
CHARYBDIS_SAFE_RANGE,
};
#define DPI_MOD POINTER_DEFAULT_DPI_FORWARD
#define DPI_RMOD POINTER_DEFAULT_DPI_REVERSE
#define S_D_MOD POINTER_SNIPING_DPI_FORWARD
#define S_D_RMOD POINTER_SNIPING_DPI_REVERSE
#define SNIPING SNIPING_MODE
#define SNP_TOG SNIPING_MODE_TOGGLE
#define DRGSCRL DRAGSCROLL_MODE
#define DRG_TOG DRAGSCROLL_MODE_TOGGLE
#endif // !NO_CHARYBDIS_KEYCODES
```
Users extending the keycode set themselves (either in their keymap, or in their userspace) must start at `CHARYBDIS_SAFE_RANGE` to avoid conflicts, _eg._:
```c
enum userspace_keycodes {
#ifndef NO_CHARYBDIS_KEYCODES
MY_FIRST_KEYCODE = CHARYBDIS_SAFE_RANGE,
#else
MY_FIRST_KEYCODE = SAFE_RANGE,
#endif // !NO_CHARYBDIS_KEYCODES
MY_SECOND_KEYCODE,
…
};
```
To disable the custom keycodes, and reduce binary size, simply add a definition in `config.h`:
```c
#define NO_CHARYBDIS_KEYCODES
```
