I am hoping someone can help me. I have a Raspberry Pi 4 and I want to use an Adaffruit backpack for displays. I have managed to install Blinka and it seems to work. I am trying to find a library for the backpack. I found on Github
Adafruit_Puthon_LED_Backpack
but this is deprecated. There is a new version for Circuit Python but I can’t find a new version for Raspberry Pi.
I have used i2c multiplexers before.
However this might not translate to your exact situation.
That’s why I wanted to offer you a guide rather than my own thoughts.
When the work week starts someone from CE staff might have more hands on experience with this exact model.
I have done some work on this and now have the backpack and display connected to the Raspberry Pi and all working. I have attached some documentation which may be useful to others.
