用php+apache+mysql在自己的电脑上搭建一个网站,或者如果你有一个网站的话也可以。可以让W5100发送查询字符串到一个网站,网站再根据收到的字符串做一个数据库写入或者查询。下面是一段php的查询和写入代码。 - $statue = $_GET['statue'];
- if($statue==NULL || $statue!=1){
- $statue=0;
- }
- switch ($statue)
- {
- case 0: getHistory();break;
- case 1: getStatue();break;
- default:getHistory();break;
-
- }
- function getStatue(){
- require('inc\conn.inc.php');
- $sensor = $_GET['sensor'];
- $sdata = $_GET['sdata'];
- $geeker = $_GET['geeker'];
- $showtime = date("Y-m-d H:i:s");
-
- if (mysqli_connect_errno()){
- echo 'can not connect to database!';
- } else {
- if($sensor==NULL || $sdata == NULL || $geeker==NULL){
- echo 'Error. Please check your data!';
-
- }else{
- $query="insert into arduino values(".'NULL'. ", '".$geeker. "', '".$sensor. "', '".$sdata. "', '".$showtime."')";
- $result = $db->query($query);
- echo 'Submitted OK!';
- }
- }
- }
- function getHistory(){
- require('inc\conn.inc.php');
- echo '<html xmlns="http://www.w3.org/1999/xhtml">
- <head><title>Arduino上传数据至网络测试页面</title></head>
- <div align="center"><h1>Arduino上传数据至网络测试历史记录</h1></div>';
-
- if (mysqli_connect_errno()){
- echo 'can not connect to database!';
- } else {
- $query='select * from arduino order by id desc limit 100';
- $result=$db->query($query);
- $num=$result->num_rows;
-
- if($num!=0)
- {
- echo '<table width="640" border="1" align="center">
- <tr>
- <td><strong>编号</strong></td>
- <td><strong>作者</strong></td>
- <td><strong>传感器</strong></td>
- <td><strong>传感器数据</strong></td>
- <td><strong>上传时间</strong></td>
- </tr>';
-
- while($allrow=$result->fetch_array()){
- echo '<tr>';
- echo '<td>'.$allrow['id'].'</td>';
- echo '<td>'.$allrow['geek'].'</td>';
- echo '<td>'.$allrow['sensor'].'</td>';
- echo '<td>'.$allrow['sensor_data'].'</td>';
- echo '<td>'.$allrow['time'].'</td>';
- echo '</tr>';
- }
- echo '</table>';
- }else{
- echo '没有历史记录可查';
- }
- }
- echo '<body></body></html>';
- $db->close();
- }

W5100的代码如下,你需要自己写获取传感器数据的部分,不过如果只是做测试的,直接使用下面的代码也行。红色的部分需要改成你自己的,黄色的部分可以改也可以不改。具体的做法参见 http://www.soxitoday.com/archives/1926.html: - #include <SPI.h>
- #include <Ethernet.h>
- [color=Red] byte mac[] = { 0x8C, 0xB8, 0×64, 0xEF, 0×71, 0×97 };
- IPAddress ip(218,23,63,34);[/color]
- EthernetClient client;
- char serverName[] = "www.lycabc.com";
- void setup() {
- Serial.begin(9600);
- while (!Serial) {
- ; // wait for serial port to connect. Needed for Leonardo only
- }
- Serial.println("Attempting to get an IP address using DHCP:");
- if (!Ethernet.begin(mac)) {
- Serial.println("failed to get an IP address using DHCP, trying manually");
- Ethernet.begin(mac, ip);
- }
- Serial.print("My address:");
- Serial.println(Ethernet.localIP());
- connectToServer();
- }
- void loop()
- {
- if (client.connected()) {
- if (client.available()) {
- char inChar = client.read();
- Serial.print(inChar);
- }
- }
- }
- void connectToServer() {
- Serial.println("connecting to server…");
- if (client.connect(serverName, 80)) {
- Serial.println("making HTTP request…");
- String Requesting;
- [backcolor=Yellow]String sensor="mysensor";//传感器的名称
- int sdata=100;//传感器的数值
- String geeker="yourname";//你的昵称[/backcolor]
- Requesting= "GET /?sensor="+sensor+"&sdata="+sdata+"&geeker="+geeker+"&statue=1 HTTP/1.1";
- client.println(Requesting);
- client.println("HOST: [url]www.lycabc.com[/url]");
- client.println();
- }
- }
