Bom dia, estou tentando Conectar o meu notebook com o Arduino
utilizando o Ethernet Shield, via roteador eu consigo normalmente,
agora computador -> arduino, não estou consiguindo, estou utilizando o
cabo crossover.
O código do Arduino é este:
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip( 192, 168, 1, 177 );
IPAddress gateway( 192, 168, 1, 1 );
IPAddress subnet( 255, 255, 255, 0 );
EthernetServer server(80);
void setup() {
Ethernet.begin(mac, ip, subnet, gateway);
server.begin();
}
void loop() {
EthernetClient client = server.available();
if (client) {
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
if (c == '\n' && currentLineIsBlank) {
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();
for (int analogChannel = 0; analogChannel < 6; analogChannel+
+) {
client.print("analog input ");
client.print(analogChannel);
client.print(" is ");
client.print(analogRead(analogChannel));
client.println("<br />");
}
break;
}
if (c == '\n') {
currentLineIsBlank = true;
}
else if (c != '\r') {
currentLineIsBlank = false;
}
}
}
delay(1);
client.stop();
}
}
utilizei o ping e esta foi a resposta:
PING 192.168.1.6 (192.168.1.6) 56(84) bytes of data.
