Such as adding DPI control, or to use the ball to scroll while holding a button. To allow for this sort of control, there is a callback for both the scroll wheel and the mouse censor. + +The default behavior for this is: + +```c +void process_wheel_user(report_mouse_t* mouse_report, int16_t h, int16_t v) { + mouse_report->h = h; + mouse_report->v = v; +} + +void process_mouse_user(report_mouse_t* mouse_report, int16_t x, int16_t y) { + mouse_report->x = x; + mouse_report->y = y; +} +``` + +This should allow you to more heavily customize the behavior. + +Alternatively, the `process_wheel` and `process_mouse` functions can both be replaced too, to allow for even more functionality. + +Additionally, you can change the DPI/CPI or speed of the trackball by calling `pmw_set_cpi` at any time.
