Nextion screen problem with DUE

Official Hardware Mega Due
11

Guys, just trying to figure out this problem, I've got the messages from the Nextion to reach the arduino through Hardware serial 2 by doing the following:

Check the file NexConfig.h for the configuration:

#define nexSerial Serial2

Removing the mention to SoftwareSerial from the NexUpload.c file;
Adding

#include"SD.h"

Including to the Setup:
nexSerial.begin(9600);

Yeah, it seems that the messages to and from the Nextion are at 9600 bps

Still will try to update the Nextion variables, but the buttons are being captured successfully.

Regards,

Luciano.
