Arduino to processing

kurtys

Hello guys i'm french boy. Sorry for ma English :) I have a project, display arduino data to processing. For this i have the card of Arduino(Mega 2560), i get data in arduino, but i can't display to arduino :(. That's is my program Arduino

char Vitesse; char Autonomie; char Utilisateur;

void setup() { Serial.begin(9600); //set baud rate on Arduino to 9600 }

void loop() { // Pour la Vitesse...... if (Serial.available() > 0) { Vitesse = Serial.read(); Serial.write(Vitesse);

}

 // Pour l'Autonomie.......

if (Serial.available()> 0) { Autonomie = Serial.read(); Serial.write(Autonomie); }

// Pour l'Utilisateurs.......... if (Serial.available()>0) { Utilisateur = Serial.read(); Serial.write(Utilisateur); } }

and this is my program Processing

import processing.serial.*;

// Attention: Changez ce numéro pour le bon port au besoin int numero_du_port = 0; // ...ou 1, 2, 3...

Serial mon_port; String vitesse = "";
String autonomie = "";
String utilisateur = "";

void setup() { size(500, 550); println("Liste des ports: \n" + Serial.list()); String nom_du_port = Serial.list()[numero_du_port]; mon_port = new Serial(this, nom_du_port, 9600); background(93, 143, 94); }

void draw() {

if (mon_port.available() != 0) { // Conversion du int en char vitesse = str(mon_port.read()); autonomie = str(mon_port.read()); utilisateur = str(mon_port.read()); }

text("Vitesse du Gyropode: " + vitesse, 10, 50); text("Batterie du Gyropode: " + autonomie, 10, 70); text("Utilisateur du Gyropode: " + utilisateur, 10, 90); } Ps: Sorry for my english. Please i need help

In the Processing menu you can select example code to run. One of the examples for serial is called SerialDuplex. Try that code because it will allow you to transmit a keyboard character out the serial port and then display a character received by the serial port.

Thank you for your help :) i test it !
