Hello I am the requester and I am very happy that the subject interests many people. I checked the solution with the icon ..good job ..and thank for this approach....

this is the solution For UNO #define UNO_RXPIN 10 #define UNO_TXPIN 11 SoftwareSerial nextionSerial(UNO_RXPIN, UNO_TXPIN); // RX, TX For MEGA #define MEGA_RX_PIN 53 #define MEGA_TX_PIN 51 SoftwareSerial nextionSerial(MEGA_RX_PIN, MEGA_TX_PIN); //...

Hi, If you can change the value that means your TX_PIN is the good one . GetValue = Rx_PIN = read pin if you cannot read there are 2 assumptions...

Hi Another possibility. Into your source code add the screen name into the variable declaration: see **ECRANS.onoff_pompBois** //---------------------------------------- #define ECRAN_1 1 ..... Nextion nex(nextionSerial); NextionPage ecran1(nex, ECRAN_1, 0, "**ECRANS**"); NextionVariableNumeric...

you solve your problem using which port on Mega ( RX3/TX3 , RX/TX2 or RX/TX1 ) ?

this is the solution For UNO #define UNO_RXPIN 10 #define UNO_TXPIN 11 SoftwareSerial nextionSerial(UNO_RXPIN, UNO_TXPIN); // RX, TX For MEGA #define MEGA_RX_PIN 53 #define MEGA_TX_PIN 51 SoftwareSerial nextionSerial(MEGA_RX_PIN, MEGA_TX_PIN); //...

Thank you a lot Dan for your great Library !!
