Hello,
So I am not an expert in arduino so maybe I can have forget a configuration but ...
I begin the guide for Arduino Yun here:
And all was good until process and bridge part.
Indeed I can change the stat of the led 13 with console but I can't with the REST URL... and I don't see the ASCII Arduino Logo with the process and curl.
Ma Yun card is connected on lan on 192.168.1.71, I can access to it configuration with http://192.168.1.71/cgi-bin/luci/webpanel/homepage and in SSH but I can't with arduino.local
My code for bridge (it's copy/paste to : http://arduino.cc/en/Tutorial/Bridge) and all it's good when I download it in my Yun card.
// Possible commands are listed here:
//
// "digital/13" -> digitalRead(13)
// "digital/13/1" -> digitalWrite(13, HIGH)
// "analog/2/123" -> analogWrite(2, 123)
// "analog/2" -> analogRead(2)
// "mode/13/input" -> pinMode(13, INPUT)
// "mode/13/output" -> pinMode(13, OUTPUT)
#include <Bridge.h>
#include <YunServer.h>
#include <YunClient.h>
// Listen on default port 5555, the webserver on the Yun
// will forward there all the HTTP requests for us.
YunServer server;
void setup() {
Serial.begin(9600);
// Bridge startup
pinMode(13,OUTPUT);
digitalWrite(13, LOW);
Bridge.begin();
digitalWrite(13, HIGH);
// Listen for incoming connection only from localhost
// (no one from the external network could connect)
server.listenOnLocalhost();
server.begin();
}
void loop() {
// Get clients coming from server
YunClient client = server.accept();
// There is a new client?
if (client) {
// Process request
process(client);
// Close connection and free resources.
client.stop();
}
delay(50); // Poll every 50ms
}
void process(YunClient client) {
// read the command
String command = client.readStringUntil('/');
// is "digital" command?
if (command == "digital") {
digitalCommand(client);
}
// is "analog" command?
if (command == "analog") {
analogCommand(client);
}
// is "mode" command?
if (command == "mode") {
modeCommand(client);
}
}
void digitalCommand(YunClient client) {
int pin, value;
// Read pin number
pin = client.parseInt();
// If the next character is a '/' it means we have an URL
// with a value like: "/digital/13/1"
if (client.read() == '/') {
value = client.parseInt();
digitalWrite(pin, value);
}
else {
value = digitalRead(pin);
}
// Send feedback to client
client.print(F("Pin D"));
client.print(pin);
client.print(F(" set to "));
client.println(value);
// Update datastore key with the current pin value
String key = "D";
key += pin;
Bridge.put(key, String(value));
}
void analogCommand(YunClient client) {
int pin, value;
// Read pin number
pin = client.parseInt();
// If the next character is a '/' it means we have an URL
// with a value like: "/analog/5/120"
if (client.read() == '/') {
// Read value and execute command
value = client.parseInt();
analogWrite(pin, value);
// Send feedback to client
client.print(F("Pin D"));
client.print(pin);
client.print(F(" set to analog "));
client.println(value);
// Update datastore key with the current pin value
String key = "D";
key += pin;
Bridge.put(key, String(value));
}
else {
// Read analog pin
value = analogRead(pin);
// Send feedback to client
client.print(F("Pin A"));
client.print(pin);
client.print(F(" reads analog "));
client.println(value);
// Update datastore key with the current pin value
String key = "A";
key += pin;
Bridge.put(key, String(value));
}
}
void modeCommand(YunClient client) {
int pin;
// Read pin number
pin = client.parseInt();
// If the next character is not a '/' we have a malformed URL
if (client.read() != '/') {
client.println(F("error"));
return;
}
String mode = client.readStringUntil('\r');
if (mode == "input") {
pinMode(pin, INPUT);
// Send feedback to client
client.print(F("Pin D"));
client.print(pin);
client.print(F(" configured as INPUT!"));
return;
}
if (mode == "output") {
pinMode(pin, OUTPUT);
// Send feedback to client
client.print(F("Pin D"));
client.print(pin);
client.print(F(" configured as OUTPUT!"));
return;
}
client.print(F("error: invalid mode "));
client.print(mode);
}
And I lance a request with : http://192.168.1.71/arduino/digital/13/0 in my web browser but nothing happened and I have not a not found just nothing.
Someone can tell me what is the stupid mistake that I made...
