连接树莓派使用
连接树莓派使用时，支持Raspbian/Ubuntu/Kali/Retropie和 WIN 10 IOT系统，支持单点触控（在某些软件界面可以支持多点触控，最高支持5点触控，具体视系统情况而定）。
由于树莓派不支持自动适配屏幕，因此在连接树莓派使用的时候，需要手动设置分辨率，否则将显示异常，这里以Raspbain为例，介绍如何设置屏幕。（其他系统的设置方法基本类似）
- 从树莓派官网下载最新的Raspbian镜像（建议下载带图形界面的版本）
- 将TF卡连接到电脑，用格式化软件将TF卡格式化
- 如果你已经烧写好镜像，请直接跳到config.txt文件的设置一步
- 使用镜像烧录软件，将准备好的镜像文件烧写到TF卡上。
- 注意，如果是下载的压缩包，需要先将压缩包解压，获得.img文件才可以
- 烧写完成后，打开TF卡BOOT目录下的config.txt文件，找到语句dtoverlay=vc4-fkms-V3D，将这条语句注释掉
- 在语句的前面加#
- 在cofnig.txt文件的最后加入以下设置语句，保存。然后将TF卡安全弹出
max_usb_current=1 hdmi_force_hotplug=1 config_hdmi_boost=10 hdmi_group=2 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0
- 将TF卡插入树莓派
- 将屏幕的Touch接口用micro USB线连接到树莓派的USB接口
- 如果树莓派的USB口供电不足，可能导致屏幕出现闪屏，可以另外连接5V电源到Power Only 接口做额外供电。
- 将屏幕的Display接口用HDMI县连接到树莓派的HDMI接口
- 如果需要音频，将耳机线接入到HP接口，注意将树莓派的音频输出设置为HDMI
- 上电启动树莓派，等待几秒后即可正常显示
连接Jetson Nano Developer Kit使用
连接Jetson Nano Developer Kit 使用时，由于主板可以自动适配屏幕，无需另外做配置
- 将屏幕的Touch接口用micro USB线连接到Jetson Nano的USB接口
- 如果Jetson Nano的USB口供电不足，可能导致屏幕出现闪屏，可以另外连接5V电源到Power Only 接口做额外供电。
- 将屏幕的Display接口用HDMI线连接到Jetson Nano的HDMI接口
- 如果需要音频，将耳机线接入到HP接口，注意将Jetson Nano音频输出接口设置为HDMI屏幕
- 上电启动Jetson Nano，等待几秒后可以看到LCD正常显示。
