Hello, I have encountered such a problem that the backlight does not work. Arduino nano and tape ws2812b 144/1m. The ribbon flashes after connecting the arduino nano to the computer but then silence and does not light, the sketch installed adalight and in the configuration of the sketch set the length of the ribbon 288 as I have 2m, I thought maybe because the arduino can not process such a number of LEDs and set 60 in the sketch but did not help, the ribbon and arduino working I checked them
