hey
I am try to read variable data from HMI to Mega 2560 and stored it value in it using Easy Nextion Library function myNex.readNumber() but i am not getting data which is stored in variable.

so plz help me.

Use code tags to format code for the forum
#include <EasyNextionLibrary.h>
#include <trigger.h>

EasyNex myNex(Serial);

uint32_t Sitering_Temp = 0,DummyCycle_Temp = 0;
uint32_t STemp = 0,DTemp = 0;

#define loop_time 2000
unsigned long timer;

void setup() {
// put your setup code here, to run once:
//Serial.begin(9600);
myNex.begin(9600);

delay(500);

timer = millis();
}

void loop() {
// put your main code here, to run repeatedly:
// Serial.println("Hello");
if(millis() - timer > loop_time){
Sitering_Temp = myNex.readNumber("S_Temp.val");
Serial.println(Sitering_Temp);
if(Sitering_Temp != 99){
STemp = Sitering_Temp;
Serial.println("STemp:");
Serial.println(STemp);
}
else if(Sitering_Temp == 99){
Sitering_Temp = STemp;
}

  timer = millis();

}
if(millis() - timer > loop_time){
DummyCycle_Temp = myNex.readNumber("D_Temp.val");

if(DummyCycle_Temp != 99){
DTemp = DummyCycle_Temp;
Serial.println("DTemp:");
Serial.println(DTemp);
}
else if(DummyCycle_Temp == 99){
DummyCycle_Temp = DTemp;
}

timer = millis();
}

}

Moved to Displays section.... Please don't post in Uncategorized again.

Please also put your code tags, the <CODE/> button.
You can edit your post to include the above by using the little pencil in the bottom right corner.

Thanks.
