testNextionNumberBox #105
Description
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
