Yeelink arduino uno + W5100 实现11个LED开关点亮
本帖最后由 布列松 于 2014-12-13 23:03 编辑Yeelink arduino uno + W5100 把11个LED开关点亮，分别接数字口{5, 6, 7, 8, 9, 14, 15, 16, 17, 18, 19}，A0～A5代替数字D14～D19。
#include <SPI.h>
#include <Ethernet.h>
#include <Wire.h>
#include <math.h>
byte buff;
#define APIKEY "xxxxxx" // 此处替换为你自己的API KEY
#define DEVICEID xxxxxx // 此处替换为你的设备编号
char flag = 0; //定义开关循环控制变量
String SENSORID[] = {"xxxxx", "xxxxx", "xxxxx","xxxxx","xxxxx","xxxxx","xxxxx","xxxxx","xxxxx","xxxxx","xxxxx"}; // 把sensor ID 依次替在这里，程序定义为数组，几个开关就写几个
byte ledPin[] = {5, 6, 7, 8, 9, 14, 15, 16, 17, 18, 19};
// assign a MAC address for the ethernet controller.
byte mac[] = { 0x00, 0x1D, 0x72, 0x82, 0x35, 0x9D};
// initialize the library instance:
EthernetClient client ;
char server[] = "api.yeelink.net"; // name address for yeelink API
unsigned long lastConnectionTime = 0; // last time you connected to the server, in milliseconds
boolean lastConnected = false; // state of the connection last time through the main loop
const unsigned long postingInterval = 3 * 1000; // delay between 2 datapoints, 30s
String returnValue = "";
boolean ResponseBegin = false;
void setup() {
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(14, OUTPUT);
pinMode(15, OUTPUT);
pinMode(16, OUTPUT);
pinMode(17, OUTPUT);
pinMode(18, OUTPUT);
pinMode(19, OUTPUT);
for (int i = 0; i < 11; i++) //I<7，几个开关，就把7改成几，其实就是循次数
{
pinMode(ledPin, OUTPUT);
}
Wire.begin();
// start serial port:
Serial.begin(57600);
// start the Ethernet connection with DHCP:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
for (;;)
;
}
else {
Serial.println("Ethernet configuration OK");
}
}
void loop() {
// if there's incoming data from the net connection.
// send it out the serial port.This is for debugging
// purposes only:
if (client.available()) {
char c = client.read();
// Serial.print(c);
if (c == '{')
ResponseBegin = true;
else if (c == '}')
ResponseBegin = false;
if (ResponseBegin)
returnValue += c;
}
if (returnValue.length() != 0 && (ResponseBegin == false))
{
Serial.println(returnValue);
if (returnValue.charAt(returnValue.length() - 1) == '1') {
Serial.println("turn on the LED");
digitalWrite(ledPin, HIGH);
}
else if (returnValue.charAt(returnValue.length() - 1) == '0') {
Serial.println("turn off the LED");
digitalWrite(ledPin, LOW);
}
returnValue = "";
flag++;
}
// if there's no net connection, but there was one last time
// through the loop, then stop the client:
if (!client.connected() && lastConnected) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
}
// if you're not connected, and ten seconds have passed since
// your last connection, then connect again and send data:
if (!client.connected() && (millis() - lastConnectionTime > postingInterval)) {
// read sensor data, replace with your code
//int sensorReading = readLightSensor();
Serial.print("yeelink:");
//get data from server
// getData();
if (flag < 11) ///更改为开关的个数
{
//get data from server
getData();
}
else
{
//put data to server
if (flag = 12) {
flag = 0; ///更改为开关的个数+1
}
}
}
// store the state of the connection for next time through
// the loop:
lastConnected = client.connected();
}
// this method makes a HTTP connection to the server and get data back
void getData(void) {
// if there's a successful connection:
if (client.connect(server, 80)) {
Serial.println("connecting...");
client.print("GET /v1.0/device/");
client.print(DEVICEID);
client.print("/sensor/");
client.print(SENSORID);
client.print("/datapoints");
client.println(" HTTP/1.1");
client.println("Host: api.yeelink.net");
client.print("Accept: *");
client.print("/");
client.println("*");
client.print("U-ApiKey: ");
client.println(APIKEY);
client.println("Content-Length: 0");
client.println("Connection: close");
client.println();
Serial.println("print get done.");
}
else {
// if you couldn't make a connection:
Serial.println("connection failed");
Serial.println();
Serial.println("disconnecting.");
client.stop();
}
// note the time that the connection was made or attempted:
lastConnectionTime = millis();
}
这段代码原本是 论坛：风生水起、口腔（戴志强）等，然后我再修改。
有几个问题请大家帮忙：
1、 if (flag < 11) ///更改为开关的个数
{
//get data from server
getData();
}
else
{
//put data to server
if (flag = 12) {
flag = 0; ///更改为开关的个数+1
}
这部分代码不明白作用，但对整个有影响。请问我要加入LM35上传数据，应该怎样修改。
2、D18、D19数字口，不知为什么无法控制。（初步验证，Yeelink的网络传输是正常的，是UNO主板的D18、D19（A4、A5）数字端口的电平电压过分的低，不知原因，更换其它UNO主板问题都一样。而且这两个口的会被其它数据口的开关控制着、联动）10、11、12、13号端口用于SPI通信；4号端口用于TF卡片选； 10号端口为W5100片选；
2014/12/13 发现W5100主板会有死机现象，LED灯开了就关不了，不知是主板问题还是代码问题。
测试视频：
http://v.youku.com/v_show/id_XODQ2NzUyMDcy.html 上视频吧，读代码多枯燥啊:( 这个还是比较厉害的！！！！！哟哟一定的使用价值！！！ 你不是买的r3网卡吗. kokomi 发表于 2014-12-22 17:14 static/image/common/back.gif
你不是买的r3网卡吗.
W5100 R3版本的 就正常 if (flag = 12) {
flag = 0; ///更改为开关的个数+1
}
是不是是应该换成falg ==12呢？这是错误吧？:L 而且我想知道我随机打开开关也是可以控制的，那flag的作用是用来干嘛的，按顺序才能打开灯吗 简单侣图 发表于 2015-1-22 14:00 static/image/common/back.gif
if (flag = 12) {
flag = 0; ///更改为开关的个数+1
}
这个我也觉得是个问题。。。。。。 纳尼:o为什么你控制那么快，我才带了六个灯就延迟很厉害 怎么将DHT11加上去，代码怎么样，谢谢！
