CrowPanel 7.0" -HMI ESP32 Display How to change screen brightness?

I have this screen working with OpenHasp and need to know:
How to increase/decrease screen brightness
I have read that Pin 4 is the display, does it accept high/low to power the screen off?

  • Hello @chris2172 ,
    The IO2 can control the screen backlight turn on/off, but the brightness can not be adjusted.

    Thanks for this.
    I now have a great-looking screen with everything I want on it and it will dim after 1 minute and turn off after 5 of inactivity.
    I was so impressed that I showed a colleague at work who also ordered his first screen,

    @chris2172 So it is possible to reduce the brightness with a PWM signal on GPIO2, contrary to what was said above?

  • @lboue
    No, the GPIO2 can't generate PWM signal.

  • Thanks for the explanation
