testNextionNumberBox

[vicplasma]

I am trying to use NexNumber to get value from n1 entered with a Nextion keyboard.
then display it/ setValue to n0.
and print it to serial.

It works till I enter a number greater than 32767 .
My simple modification of testNextionNumberBox sketch is below.

Please advise I need to be able to enter 20000000 and ever number in between.

#include "Nextion.h"

include <NexNumber.h> // could not find till I added.

uint32_t number = 0;

NexNumber n0 = NexNumber(0, 1, "n0");
NexNumber n1 = NexNumber(0,3,"n1");

void setup() {
nexInit();

}

void loop() {
// ****** Per online suggestion I modified NexNumber.cpp utoa(number, buf, 10);to ultoa(number, buf, 10);

n1.getValue(&number); // n1 is set by a Nextion Keyboard
// GET NEXTION VALUE FROM n1 page 0 ////////

n0.setValue(number);// SET THE VALUE to uint32_t number to n0, to verify arduino has the number /////////

Serial.println(number);// Serial print number again to verify number is correct//

}

The HMI is simple n0 is a number box local .
n1 is a number box global keybdA because keybdB keys disappear after a few seconds.

Data from my test below

Number entered in n1 Number didplayed n1 Number Serial Printed

32767 32767 32767

32768 0 4294936223 had to restart serial monitor 0 just before err
