CrowPanel 5.0 V3 - DIS07050H, Backlight Controller doesn't work
Hi, I'm a newbie in CrowPanel - but have read many hints and tutorials about CrowPanel 5.0 and I' really happy about this new ESP32 Display and I want to use this for my Homematic Display.
So for this purpose I want to switch of the backlight, if no use for let's say 1min. I've read some discussion also in this Forum and it should be possible to switch of the backlight via "IO2_LCD_BL_CTR", but I can't get it as expected 
I'm using Arduino IDE 2.3.4 AppImage, esp32 (Espressif Systemes) board Lib 2.0.15 & "ESP32S3 Dev Module" as the board.
In Arduino IDE I've tried:
pinMode(2,OUTPUT);
digitalWrite(2,LOW);
doesn't work. Maybe I've used a wrong pin?
Any hint/help is appreciated, thanks a lot!
