Ensure that the LCD is an EDP interface and the touch is an IIC interface. In principle, it can light up normally, but the driver part needs to be modified. Check if there are any universal specifications later.

@jack_admin 你好，这个的引脚是怎么使用的，我用引脚显示无权限

这是用V4L2-TEST打开时demsg打印的

@花月
ov5647兼容

可以使用gstreamer套件调用

@大法师
好 有时间我试试

@haiting2022 如果需要通过命令行拨号方式上网，更新一下附件驱动。v5.10.11.zip

@tonyone0902 显示异常的时候，打印一下下面两个命令，结果发上来：
sudo cat /sys/kernel/debug/dri/0/summary
sudo cat /sys/kernel/debug/dw-hdmi0/status

@大法师 建议尽快支持一下树莓派的HQ Camera，传感器型号是IMX477R，现在这款摄像头很火，可以匹配各种不同的镜头。IMX708支持自动对焦，是新出的产品。

@jack_admin 已经成功

@AugustRobot_Zou x谢谢，果然是如此。修改后两个语句初始化。可以用了。

@xws 部分适配器功率切换瞬间会掉电，会导致机器重启。

@xws
5V~24V 都可以的

@retroman Because the pi 4b box has no power key location, direct use will cause pwr key is stuck. In addition, the size of the DP output port is larger than Pi 4b, and the size of the metal radiator of PI4b is too far from the DP interface. 3D printing is the only option before the surrounding accessories of the cool pi come out.

How about OV9281, compatible with Raspberry PI 4B
