  • user_data – use lv_draw_eve_display_get_user_data to get this pointer inside the op_cb

Returns:

the EVE display

void *lv_draw_eve_display_get_user_data(lv_display_t *disp)

Parameters:

disp – pointer to the lv_draw_eve display

Returns:

the user_data pointer

lv_indev_t *lv_draw_eve_touch_create(lv_display_t *disp)

Parameters:

disp – pointer to the lv_draw_eve display

Returns:

the EVE touchscreen indev
