into config.h.
### 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.
