Hello everybody
I try to send data from my arduino nano to my nextion display but it doesn't work.
I would like to send datas from arduino without libraries
I made this code :
Int SortieA = 6;
void setup() {
Sérial.begin(9600);
}
void loop () {
SortieA = 12;
Serial.print("ne.val=");
Serial.print(SortieA);
Sérial.print(0xff);
Sérial.print(0xff);
Sérial.print(0xff);
delay(200);
}
And i put
Rx-->tx
Tx-->RX
Could you help me please i m lost ?
Thank you in advance
Hello,
Please use the </> tag to include code.
So far, ne is not a valid object name, must be something like n0 or n1,n2...etc, if it is numeric, or t0,t1,t2...etc, if it is text.
Int SortieA = 6;
void setup() {
Sérial.begin(9600);
}
void loop () {
SortieA = 12;
Serial.print("ne.val="); // ne is not a valid object name. Must be something like n0 or n1 , n2
Serial.print(SortieA);
Serial.write(0xff); // Sérial.print(0xff); //
Serial.write(0xff); // Sérial.print(0xff); //
Serial.write(0xff); // Sérial.print(0xff); //
// Serial.print("\xFF\xFF\xFF"); // Or you can use this instead of 3 times Serial.write
delay(200);
}
I prefer the Serial.print("\xFF\xFF\xFF"); , as it sends ASCII .
