SiS USB 触摸屏通常是一种外接式触摸屏设备通过 USB 接口连接到计算机或其他设备上。这种触摸屏设备可以提供触摸输入功能用户可以通过手指或触控笔在屏幕上进行操作实现点击、拖动、缩放等操作。 SiS USB 触摸屏通常需要安装相应的驱动程序才能正常工作在计算机系统中被识别为触摸输入设备。驱动程序会将触摸屏输入转换为计算机可识别的信号从而实现触摸屏在操作系统中的正常使用。 二驱动文件配置
1. hid_sis内核模块驱动文件 hid-sis_ctrl.c :在Linux内核中HID设备驱动程序负责与各种输入设备如键盘、鼠标、游戏手柄等进行通信和管理。包含与特定类型的HID设备通信的代码实现包括设备的初始化、数据传输、事件处理等功能。这个文件可能会被编译到内核中以便在系统启动时加载并与相应的HID设备进行交互。 /** Character device driver for SIS multitouch panels control** Copyright (c) 2023 SIS, Ltd.**//** This program is free software; you can redistribute it and/or modify it* under the terms of the GNU General Public License as published by the Free* Software Foundation; either version 2 of the License, or (at your option)* any later version.*/#include linux/hid.h

};3. 移植hid_sis驱动
a. 将驱动(hid-sis_ctrl.chid-sis_ctrl.h)拷贝到下面的文件夹
kernel/drivers/hid/b. 在 Makefile 中添加hid-sis_ctrl设备
kernel/drivers/hid/Makefile:#/ SiSdrv Start /
obj-$(CONFIG_HID_SIS_CTRL) hid-sis_ctrl.o
#/ SiSdrv End /c. 在 Kconfig 中添加hid-sis_ctrl

1.授予sis节点权限
