去年看了reiyawea的短信铃+ESP8266改造为天气显示器帖子，
https://www.yleee.com.cn/forum.php?mod=viewthread&tid=45863

用esp8266能做天气预报。
照着做了，但是原作者的方案将天气信息的解码部分放在另外的服务器上来实现，国内连不上，只能显示一堆错误的数据。
随后在网上搜索了，没有找到完整的能在国内方便使用的完整的代码。

只好自己动手了。

首先确定天气预报的源，
参考链接 有哪些免费开放且收录城市较完整的天气 API 接口？http://www.zhihu.com/question/20521716/answer/21247376
我找了方便注册，开放接口，免费的和风天气http://www.heweather.com/。
（P.S忘了当初不选国家气象局源的原因了，可能是注册麻烦。希望现在这个不要用着就挂了）
（做好放了3个月，突然发现之前的程序无法正常使用了，3月返回的get请求，第9波是是JSON代码，到了6月变成第7波是JSON代码了，只好改程序，使用字符串长度来判断）


和风天气的数据是 JSON格式的，就是你发个请求过去，它会回你一大坨数据。

这么一大坨，普通的arduino板肯定无法处理了。

网上找了个arduino 的JSON库，可以从JSON中提取出所需要的数据。经过反复测试，数据量太大，无法解析。（砍掉一半数据是可以解析的）
后来使用了字符串查找函数，取出了所需的数据，修改原程序，任务完成。
做完放了三个月，现在有空整理下发出来。

(P.S 后来原作者又更新了NTP获取时间的功能，等哪天有空再给抄上。)

• 准备元件
  

esp8266 我选的是ESP-12
OLED 用1306控制芯片，IIC接口
LDO之前选过XC6206，但是电流太小，初始化的时候老是会复位

• 安装 arduino 1.6.5
  

我用的是1.6.5 其它版本未测试，太老的不支持新功能。

• 安装 esp8266 扩展
  

Installing the ESP8266 Arduino Addon There are a variety of development environments that can be equipped to program the ESP8266. You can go with a simple Notepad/gcc setup, or fine-tune an Eclipse environment, use a virtual machine provided by Espressif, or come up with something of your own. Fortunately, the amazing ESP8266 community recently took the IDE selection a step further by creating an Arduino addon. If you’re just getting started programming the ESP8266, this is the environment we recommend beginning with, and the one we’ll document in this tutorial. This ESP8266 addon for Arduino is based on the amazing work by Ivan Grokhotkov and the rest of the ESP8266 community. Check out the ESP8266 Arduino GitHub repository for more information. Installing the Addon With the Arduino Boards Manager With the release of Arduino 1.6.4, adding third party boards to the Arduino IDE is easily achieved through the new board manager. If you’re running an older version of Arduino (1.6.3 or earlier), we recommend upgrading now. As always, you can download the latest version of Arduino fromarduino.cc. To begin, we’ll need to update the board manager with a custom URL. Open up Arduino, then go to the Preferences (File > Preferences). Then, towards the bottom of the window, copy this URL into the “Additional Board Manager URLs” text box: COPY CODE http://arduino.esp8266.com/stable/package_esp8266com_index.json If you already have a URL in there, and want to keep it, you can separate multiple URLs by placing a comma between them. (Arduino 1.6.5 added an expanded text box, separate links in here by line.) Hit OK. Then navigate to the Board Manager by going to Tools > Boards > Boards Manager. There should be a couple new entries in addition to the standard Arduino boards. Look for esp8266. Click on that entry, then select Install. The board definitions and tools for the ESP8266 Thing include a whole new set of gcc, g++, and other reasonably large, compiled binaries, so it may take a few minutes to download and install (the archived file is ~110MB). Once the installation has completed, an Arduino-blue “INSTALLED” will appear next to the entry. Selecting the ESP8266 Thing Board With the Board addon installed, all that’s left to do is select “ESP8266 Thing” from the Tools >Boards menu. Then select your FTDI’s port number under the Tools > Port menu. Upload Blink To verify that everything works, try uploading the old standard: Blink. Instead of blinking pin 13, like you may be used to though, toggle pin 5, which is attached to the onboard LED. COPY CODE #define ESP8266_LED 5void setup() {  pinMode(ESP8266_LED, OUTPUT);}void loop() {  digitalWrite(ESP8266_LED, HIGH);  delay(500);  digitalWrite(ESP8266_LED, LOW);  delay(500);} If the upload fails, first make sure the ESP8266 Thing is turned on – the red “PWR” LED should be illuminated. Faster Uploads! The serial upload speed defaults to 115200 bps, which is reliable, but can feel a bit slow. You can increase the upload speed by a factor of about 8 by selecting 921600 under the Tools > Upload Speed menu. This faster upload speed can be slightly less reliable, but will save you loads of time! There are still some bugs to be fleshed out of the esptool, sometimes it may take a couple tries to successfully upload a sketch. If you continue to fail, try turning the ESP8266 Thing on then off, or unplug then replug the FTDI in. If you still have trouble, get in touch with our amazing tech support team. 来源： https://learn.sparkfun.com/tutorials/esp8266-thing-hookup-guide/installing-the-esp8266-arduino-addon

编译时有可能会出现下图错误，原因是某个库文件有问题，把它替换掉就行了。


使用附件中的文件替换
C:\Documents and Settings\Administrator\Application Data\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\1.20.0-26-gb404fb9\xtensa-lx106-elf\lib\libm.a

这个牛!刚好有ESP8266模块,可以测试以下.非常感谢楼主分享!

返回的数据格式，总会变， 不实际 。。。。。。。。。

reiyawea

这就奇怪了，我这里还是能连的。可能是不同地区连接海外服务器有不同的限制吧。
作者开的私服会把原始的超长数据精简掉，以便于8266处理。看起来应该众筹在国内开个同样的私服。作者的私服也是开源的。
感觉天气不太实用，每天就看一次，用手机也足够了，还是NTP更实用一点，加个刷新闻功能或许不错，随时了解时事。

我碰到个问题,就是arduino的ESP8266扩展无法安装,速度特别慢,有手动安装的方法吗?版本 1.6.5

hefanghua

如果直接从预报网站搜刮HTML文件放入SD卡，然后用单片机解析呢？

既然都能搜刮html了，搜刮JSON格式的数据应该会比较省力。
