### Rotate Mouse Axes :id=rotate-mouse-axes
|
||||
|
||||
Transform the output of the device with a clockwise rotation of 90, 180, or 270
|
||||
degrees.
|
||||
|
||||
When compensating for device orientation, rotate the output the same amount in
|
||||
the opposite direction. E.g. if the normal device orientation is considered to
|
||||
be North-facing, compensate as follows:
|
||||
|
||||
```c
|
||||
#define PS2_MOUSE_ROTATE 270 /* Compensate for East-facing device orientation. */
|
||||
```
|
||||
```c
|
||||
#define PS2_MOUSE_ROTATE 180 /* Compensate for South-facing device orientation. */
|
||||
```
|
||||
```c
|
||||
#define PS2_MOUSE_ROTATE 90 /* Compensate for West-facing device orientation. */
|
||||
```
|
||||
|
||||
### Debug Settings :id=debug-settings
|
||||
|
||||
To debug the mouse, add `debug_mouse = true` or enable via bootmagic.
