软件IDE：Arduino 1.6.3
1、库的安装：
从https://github.com/jcw/ethercard 下载源码包，解压，复制ethercard-master文件夹到Arduino的安装目录所在的库文件夹下：D:\Program Files (x86)\Arduino\libraries，并且重命名为EtherCard
2、打开Arduino
复制相关代码，保存，编译，上传。
#include <EtherCard.h>
static byte mymac[] = {0xDD,0xDD,0xDD,0x00,0x00,0x01}; //这里是问题所在
static byte myip[] = {,,,};
byte Ethernet::buffer[];
const int ledPin = ;
boolean ledStatus;
char* on = "ON";
char* off = "OFF";
char* statusLabel;
char* buttonLabel;
void setup () {
Serial.begin();
Serial.println("WebLed Demo");
if (!ether.begin(sizeof Ethernet::buffer, mymac, ))
Serial.println( "Failed to access Ethernet controller");
else
Serial.println("Ethernet controller initialized");
if (!ether.staticSetup(myip))
Serial.println("Failed to set IP address");
Serial.println();
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
ledStatus = false;
}
void loop() {
word len = ether.packetReceive();
word pos = ether.packetLoop(len);
if(pos) {
if(strstr((char *)Ethernet::buffer + pos, "GET /?status=ON") != ) {
Serial.println("Received ON command");
ledStatus = true;
}
if(strstr((char *)Ethernet::buffer + pos, "GET /?status=OFF") != ) {
Serial.println("Received OFF command");
ledStatus = false;
}
if(ledStatus) {
digitalWrite(ledPin, HIGH);
statusLabel = on;
buttonLabel = off;
} else {
digitalWrite(ledPin, LOW);
statusLabel = off;
buttonLabel = on;
}
BufferFiller bfill = ether.tcpOffset();
bfill.emit_p(PSTR("HTTP/1.0 200 OK\r\n"
"Content-Type: text/html\r\nPragma: no-cache\r\n\r\n"
"<html><head><title>WebLed</title></head>"
"<body>LED Status: $S "
"<a><input type=\"button\" value=\"$S\" onClick=\"location.href='/?status=$S';\"></a>"
"</body></html>"
), statusLabel, buttonLabel, buttonLabel);
ether.httpServerReply(bfill.position());
}
}
3、设置电脑ip为192.168.2.2
4、浏览器登录192.168.2.1
