Hi,
I'm using the basic code for on/off relay:
There is any way to modify the code that the client connection will be as an interrupt? (during the delay(3000))?
Thanks!
I'm using the basic code for on/off relay:
Code: Select all
#include <ESP8266WiFi.h>
const char* ssid = "your-ssid";
const char* password = "your-password";
// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
// prepare GPIO2
pinMode(2, OUTPUT);
digitalWrite(2, 0);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.println(WiFi.localIP());
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String req = client.readStringUntil('\r');
Serial.println(req);
client.flush();
// Match the request
int val;
if (req.indexOf("/gpio/0") != -1)
val = 0;
else if (req.indexOf("/gpio/1") != -1)
val = 1;
else {
Serial.println("invalid request");
client.stop();
return;
}
// Set GPIO2 according to the request
digitalWrite(2, val);
delay (3000);
client.flush();
// Prepare the response
String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<!DOCTYPE HTML>\r\n<html>\r\nGPIO is now ";
s += (val)?"high":"low";
s += "</html>\n";
// Send the response to the client
client.print(s);
delay(1);
Serial.println("Client disonnected");
// The client will actually be disconnected
// when the function returns and 'client' object is detroyed
}
There is any way to modify the code that the client connection will be as an interrupt? (during the delay(3000))?
Thanks!
