[SOLVED] Increase brightness with DSI connection

[nagras]

Hello
I have a problem with the brightness of the Waveshare 7.9 DSI screen.

I have a Raspi PI4 2GB, I use the latest version of Moode
I insert the correct line in /boot/firmware/config.txt
I set the parameters in "DSI displays (Pi Touch1/Touch2)" everything works fine, except the brightness. you can't go beyond 31 and the screen remains dim.

On the waveshare site I find the command to install the file for increase the brightness.

I install it and try
via an SSH connection I launch the command "echo 255 | sudo tee /sys/class/backlight/*/brightness" and the brightness also works, until the next reboot. Then dim again.

Thanks for any replies

The help for the DSI Brightness setting is below.
"Touch1: 0-255, Touch2: 1-31"

I can prolly add a Type "Other" with 0-255 brightness range and 0|90|180|270 rotation options

In my case, a 90° rotation would be needed and therefore the Touch1 configuration would be used

I made the change and added Type "Other". You should be all set in upcoming 9.3.4

Hi Tim
I have installed the latest version of Moode and now for the Waveshare DSI 7.9 screen, just insert the correct line in "/boot/firmware/config.txt" with the rotation of 90° and everything works fine.

Thanks
