5. M5.Lcd.setBrightness() not working

M5.Lcd.setBrightness() not working

  • J

    The core2 does use AXP192's DC3 channel and generates the LCD backlight voltage. I have tried to modify the LCD brightness with M5.Lcd.setBrightness(val). But there is not change! In M5.init(), the DC3 PWM channel seems be set to 80. In the previous M5Stack core API the value could be changed in between 0-255. Any ideas?

  • Hello @jhubsch

    on M5Core2 LCD brightness is controlled by AXP192 (as you've already figured out yourself) so changing LCD brightness should work with:

    M5.Axp.SetLcdVoltage(v); // v from 2500 to 3300

    Thanks
