Re: 2x LCD arduino IC2 / Matrix.dll
So is this multiple LCD from one arduino?
Different lines to different LCD or all lines duplicated on all LCD's?

Re: 2x LCD arduino IC2 / Matrix.dll
ITA vorrei utlizzarlo come unico grande LCD, per visualizzare più informazioni contemporaneamente
ENG: I would like to use it as the only large LCD, to view more information at once

Re: 2x LCD arduino IC2 / Matrix.dll
OK, this sounds more like an arduino project than an LCD Smartie project.
Do you already have an arduino sketch for one display?
Take a look at https://lastminuteengineers.com/i2c-lcd ... -tutorial/ for information on I2C Address of LCD.
Each screen needs its own address.
