一、USB HID驱动
二、查看鼠标信息
ls -l /dev/input/by-id/
root@rk3506-buildroot:/dev/input# ls -l /dev/input/by-id/
total 0
lrwxrwxrwx 1 root root 9 Jan 1 00:00 usb-Compx_2.4G_Dual_Mode_Mouse-event-if01 -> ../event7
lrwxrwxrwx 1 root root 9 Jan 1 00:00 usb-Compx_2.4G_Dual_Mode_Mouse-event-mouse -> ../event5
lrwxrwxrwx 1 root root 9 Jan 1 00:00 usb-Compx_2.4G_Dual_Mode_Mouse-if01-event-kbd -> ../event6
root@rk3506-buildroot:/dev/input#
三、lvgl接入鼠标设备
不用/dev/input/event5是因为鼠标重新插入后event可能会变
四、创建鼠标样式并绑定鼠标
static void cursor_create(lv_indev_t * indev )
{lv_obj_t * cursor = lv_obj_create(lv_scr_act());lv_obj_set_size(cursor, 8, 8);lv_obj_set_style_bg_color(cursor, lv_color_white(), 0);lv_obj_set_style_bg_opa(cursor, LV_OPA_COVER, 0);lv_obj_set_style_radius(cursor, LV_RADIUS_CIRCLE, 0);lv_obj_clear_flag(cursor, LV_OBJ_FLAG_SCROLLABLE);lv_indev_set_cursor(indev, cursor);if (!indev) {printf("mouse indev create failed!\n");}
}
样式可以根据自己的喜好进行创建
