1.2" 4-Digit 7-Segment Display w/I2C Backpack brightness in

by jokre on Wed Jan 13, 2021 8:52 am

I have an Adafruit 4-digit display attached to a Raspberry Pi. The display itself works as expected, but it's not possible to set the brightness.

The use of "display.brightness" (with any valid value) doesn't change anything, it just runs at standard/default brightness. It doesn't seem to matter where in the code I try to invoke the brightness control.

Related to the following product

Code used (or at least based on it)

What am I doing wrong?
