Other using of Pins on no using chain

Hello together,

I’ve a Project where I’m using two chains led matrix with Python binding. Is it possible to use the Pins of not using third chain row for other actors like a relay with no problems or is the library always blocking the pins of all chain rows?

Thank you very much


In my experience it is fine to use pins of unused chains for other things. I have used them for LEDs and buttons and there is no interference. Signals are probably only going to pins for 2nd or 3rd chains if you are adding the flag for them.
