Nextion screen problem with DUE

Official Hardware Mega Due
5

dlloyd:
Just noticed you should be using Serial2 for pins 18 and 19...

Nextion myNextion(Serial2, 9600); //TOUCH A ---> TX to pin 18 and RX to pin 19

Actually that is only comment because I am using 2 touch screens one on SERIAL1 and the other on SERIAL2

Note that on the Due, pins 0 and 1 are 3.3V ... pin0 (RX0) has already been level shifted to 3.3V using a single bus buffer.

This is why I dont understand why it does not work. I only get "e ÿÿÿ" instead of for exemple 65 0 4 1 ffff ffff ffff

On pins 0 and 1 I get this rubbish e ÿÿÿ and on the other serials nothing at all, the TX/RX LEDs on the DUE dont even blink when I press a button on the touchscreen.

Any other ideas?
