So I’m trying to change the brightness on the HyperPixel 4 (touch and non-touch). I could only find this solution online, and it does not work:
wiringpi is installed. “gpio” is an accepted command, these don’t return an error, but they do nothing to the brightness
# Set the pin to PWM mode gpio -g mode 19 pwm # Set the value/brightness to 60 gpio -g pwm 19 60
I even tried 0, 20, 90, 1023 as brightness values.
As well I did reboot to see if that was necessary. Still nothing
I’m on a Raspberry Pi 4B
