Its possible to hook up a PS/2 mouse (for example touchpads or trackpoints) to your keyboard as a composite device.
Then, decide whether to use USART (best), interrupts (better) or busywait (not recommended), and enable the relevant option.
There are three available modes for hooking up PS/2 devices: USART (best), interrupts (better) or busywait (not recommended).
### Busywait version
@ -1316,6 +1316,116 @@ In your keyboard config.h:
#endif
```
### Additional Settings
#### PS/2 mouse features
These enable settings supported by the PS/2 mouse protocol: http://www.computer-engineering.org/ps2mouse/
```
/* Use remote mode instead of the default stream mode (see link) */
#define PS2_MOUSE_USE_REMOTE_MODE
/* Enable the scrollwheel or scroll gesture on your mouse or touchpad */
#define PS2_MOUSE_ENABLE_SCROLLING
/* Some mice will need a scroll mask to be configured. The default is 0xFF. */
#define PS2_MOUSE_SCROLL_MASK 0x0F
/* Applies a transformation to the movement before sending to the host (see link) */
#define PS2_MOUSE_USE_2_1_SCALING
/* The time to wait after initializing the ps2 host */
#define PS2_MOUSE_INIT_DELAY 1000 /* Default */
```
You can also call the following functions from ps2_mouse.h
```
void ps2_mouse_disable_data_reporting(void);
void ps2_mouse_enable_data_reporting(void);
void ps2_mouse_set_remote_mode(void);
void ps2_mouse_set_stream_mode(void);
void ps2_mouse_set_scaling_2_1(void);
void ps2_mouse_set_scaling_1_1(void);
void ps2_mouse_set_resolution(ps2_mouse_resolution_t resolution);
void ps2_mouse_set_sample_rate(ps2_mouse_sample_rate_t sample_rate);
```
#### Fine control
Use the following defines to change the sensitivity and speed of the mouse.
Note: you can also use `ps2_mouse_set_resolution` for the same effect (not supported on most touchpads).
```
#define PS2_MOUSE_X_MULTIPLIER 3
#define PS2_MOUSE_Y_MULTIPLIER 3
#define PS2_MOUSE_V_MULTIPLIER 1
```
#### Scroll button
If you're using a trackpoint, you will likely want to be able to use it for scrolling.
Its possible to enable a "scroll button/s" that when pressed will cause the mouse to scroll instead of moving.
To enable the feature, you must set a scroll button mask as follows:
```
#define PS2_MOUSE_SCROLL_BTN_MASK (1<<PS2_MOUSE_BUTTON_MIDDLE) /* Default */
```
To disable the scroll button feature:
```
#define PS2_MOUSE_SCROLL_BTN_MASK 0
```
The available buttons are:
```
#define PS2_MOUSE_BTN_LEFT 0
#define PS2_MOUSE_BTN_RIGHT 1
#define PS2_MOUSE_BTN_MIDDLE 2
```
You can also combine buttons in the mask by `|`ing them together.
Once you've configured your scroll button mask, you must configure the scroll button send interval.
This is the interval before which if the scroll buttons were released they would be sent to the host.
After this interval, they will cause the mouse to scroll and will not be sent.
```
#define PS2_MOUSE_SCROLL_BTN_SEND 300 /* Default */
```
To disable sending the scroll buttons:
```
#define PS2_MOUSE_SCROLL_BTN_SEND 0
```
Fine control over the scrolling is supported with the following defines:
```
#define PS2_MOUSE_SCROLL_DIVISOR_H 2
#define PS2_MOUSE_SCROLL_DIVISOR_V 2
```
#### Debug settings
To debug the mouse, add `debug_mouse = true` or enable via bootmagic.
```
/* To debug the mouse reports */
#define PS2_MOUSE_DEBUG_HID
#define PS2_MOUSE_DEBUG_RAW
```
## Safety Considerations
You probably don't want to "brick" your keyboard, making it impossible
