Т.к. на данный момент у меня под рукой были Arduino Uno и Ethernet Shield W5100, решил проверить на них.
Скетч на основе ChatServer.
Код:
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network.
// gateway and subnet are optional:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};
IPAddress ip(192, 168, 0, 177);
IPAddress myDns(192,168,0, 1);
IPAddress gateway(192, 168, 0, 1);
IPAddress subnet(255, 255, 255, 0);
// telnet defaults to port 4711
EthernetServer server(4711);
boolean alreadyConnected = false; // whether or not the client was connected previously
void setup() {
// initialize the ethernet device
Ethernet.begin(mac, ip, myDns, gateway, subnet);
// start listening for clients
server.begin();
// Open serial communications and wait for port to open:
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.print("Chat server address:");
Serial.println(Ethernet.localIP());
}
void loop() {
// wait for a new client:
EthernetClient client = server.available();
// when the client sends the first byte, say hello:
if (client) {
if (!alreadyConnected) {
// clear out the input buffer:
client.flush();
Serial.println("We have a new client");
alreadyConnected = true;
}
if (client.available() > 0) {
// read the bytes incoming from the client:
char thisChar = client.read();
// echo the bytes to the server as well:
Serial.write(thisChar);
}
}
}
Работает.
В результате имеем:
