Thanks. Now it's clear. Unfortunately, I don't understand why the project isn't working with 1 device.

Make sure you have the latest version of the LedControl code. Check for updated in your Arduino IDE.

The problem was when I put 1 device in initialization and then in shutdown, setIntensity, setRow also used 1. But there must be 0, because it's the address of the 1 device. Thank you so much for help
