Communication between Maxi Automation and Nextion Display

Post by marcel00 » Fri Oct 11, 2019 1:46 pm

Hello

So far I worked with an Arduino Mega and a Nextion Enhanced display.Communication is via serial2 at 112500 baud without any issues. If I connect
RX2 and TX2 of Nextion display to TXD2(X2.22) and RXD2(X2.23) and power up the Nextion display via external 5V with common ground I am not able to communicate anymore. The Arduino IDE was used and the same program was flashed to the Maxi Automation. What can be the reason for that?

Kind regards
Marcel
