Yeelink初步体验

环境

Qemu: 2.8.0
开发板：vexpress-ca9

概述

    前面的博文已经使我们的虚拟开发板具备了访问外网的目的，离物联网越来越近了。要玩物联网，Yeelink不得不说，它提供了云平台，可以将设备的数据上传到云端，然后可以通过手机客户端或在网页端查看或修改，从而达到用手机客户端跟嵌入式设备通信的目的。
    下面我们实现一个非常简单的功能： 添加一个虚拟开关，通过Yeelink的手机客户端或在网页端可以查看和修改这个开端的状态，而我们的板子会每隔2s联网读取一次这个虚拟开关的状态，最后板子根据开关的状态打印不同的提示。

正文

一、首先登陆Yeelink官网，手动添加一个device，然后在该device下面再创建一个sensor用来代表虚拟开关。

二、为Python添加requests模块
Requests 是用Python语言编写，基于urllib，采用Apache2 Licensed开源协议的HTTP库。它比urllib更加方便，可以节约我们大量的工作，完全满足HTTP测试需求。
1、下载requests模块
下载地址： https://pypi.python.org/pypi/requests/2.3.0 或 requests-2.3.0.tar.gz
解压后：
  1. $ls
  2. HISTORY.rst  NOTICE      requests/           setup.cfg
  3. LICENSE      PKG-INFO    requests.egg-info/  setup.py*
  4. MANIFEST.in  README.rst  requirements.txt    test_requests.py*
其中的requests既可以用于Python2也可以用于Python3，然后将这个requests目录拷贝到对应Python的site-packages下面。
在导入requests模块的时候，会提示找不到zlib模块。
2、重新编译Python，支持zlib
下载zlib： http://www.zlib.net/zlib-1.2.11.tar.gz 或 zlib-1.2.11.tar.gz 
  • 编译zlib：
  1. #!/bin/bash
  3. export CC=arm-none-linux-gnueabi-gcc
  5. ../zlib-1.2.11/configure \
  6. 	--prefix=`pwd`
修改Makefile，修改AR和RANLIB如下：
  1. AR=arm-none-linux-gnueabi-ar
  2. RANLIB=arm-none-linux-gnueabi-ranlib
然后执行make && make install
  • 编译Python3：
  1. #!/bin/bash
  3. ../Python-3.6.0/configure \
  4.     --host=arm-none-linux-gnueabi \
  5.     --build=armv7 \
  6.     --prefix=`pwd` \
  7.     --enable-ipv6 \
  8.     --enable-shared \
  9.     ac_cv_file__dev_ptmx="yes" \
  10.     ac_cv_file__dev_ptc="no" \
  11.     LDFLAGS="-L/home/pengdonglin/disk_ext/Third_Part/SQlite3/aarch32/lib \
  12.     -L/home/pengdonglin/disk_ext/Third_Part/Readline/aarch32/lib \
  13.     -L/home/pengdonglin/disk_ext/Third_Part/Termcap/aarch32/lib \
  14.     -L/home/pengdonglin/disk_ext/Third_Part/Zlib/aarch32/lib"\
  15.     CPPFLAGS="-I/home/pengdonglin/disk_ext/Third_Part/SQlite3/aarch32/include \
  16.     -I/home/pengdonglin/disk_ext/Third_Part/Readline/aarch32/include \
  17.     -I/home/pengdonglin/disk_ext/Third_Part/Termcap/aarch32/include \
  18.     -I/home/pengdonglin/disk_ext/Third_Part/Zlib/aarch32/include"\
  19.     LDLAST="-L/home/pengdonglin/disk_ext/Third_Part/Readline/aarch32/lib \
  20.     -L/home/pengdonglin/disk_ext/Third_Part/Termcap/aarch32/lib \
  21.     -L/home/pengdonglin/disk_ext/Third_Part/Zlib/aarch32/lib"
  23. make -j4
  24. make install
  • 编译Python2：
mk1_conf.sh:
  1. #!/bin/bash
  3. ../Python-2.7.13/configure --prefix=`pwd` \
  4.     --host=arm-none-linux-gnueabi \
  5.     --build=x86_64-linux-gnu \
  6.     --enable-ipv6 \
  7.     --enable-shared \
  8.     ac_cv_file__dev_ptmx="yes" \
  9.     ac_cv_file__dev_ptc="no" \
  10.     LDFLAGS="-L/home/pengdonglin/disk_ext/Third_Part/SQlite3/aarch32/lib \
  11.     -L/home/pengdonglin/disk_ext/Third_Part/Readline/aarch32/lib \
  12.     -L/home/pengdonglin/disk_ext/Third_Part/Termcap/aarch32/lib \
  13.     -L/home/pengdonglin/disk_ext/Third_Part/Zlib/aarch32/lib"\
  14.     CPPFLAGS="-I/home/pengdonglin/disk_ext/Third_Part/SQlite3/aarch32/include \
  15.     -I/home/pengdonglin/disk_ext/Third_Part/Readline/aarch32/include \
  16.     -I/home/pengdonglin/disk_ext/Third_Part/Termcap/aarch32/include \
  17.     -I/home/pengdonglin/disk_ext/Third_Part/Zlib/aarch32/include"\
  18.     LDLAST="-L/home/pengdonglin/disk_ext/Third_Part/Readline/aarch32/lib \
  19.     -L/home/pengdonglin/disk_ext/Third_Part/Termcap/aarch32/lib \
  20.     -L/home/pengdonglin/disk_ext/Third_Part/Zlib/aarch32/lib"\
mk2_make.sh:
  1. #!/bin/bash
  3. make HOSTPYTHON=../x86_64/python \
  4.     HOSTPGEN=../x86_64/Parser/pgen \
  5.     BLDSHARED="arm-none-linux-gnueabi-gcc -shared" \
  6.     CROSS_COMPILE=arm-none-linux-gnueabi- \
  7.     CROSS_COMPILE_TARGET=yes \
  8.     HOSTARCH=arm-none-linux-gnueabi \
  9.     BUILDARCH=x86_64-linux-gnu \
  10.     -j4
mk3_install.sh:
  1. #!/bin/bash
  3. make install HOSTPYTHON=../x86_64/python \
  4.     BLDSHARED="arm-none-linux-gnueabi-gcc -shared" \
  5.     CROSS_COMPILE=arm-none-linux-gnueabi- \
  6.     CROSS_COMPILE_TARGET=yes \
  7.     prefix=`pwd`
  • 然后修改mk_ramdisk.sh:
  1. #!/bin/bash
  3. thiry_part=/home/pengdonglin/disk_ext/Third_Part/
  4. cross_compile=/home/pengdonglin/disk_ext/Cross_Compiler/aarch32/
  6. sudo rm -rf rootfs
  7. sudo rm -rf tmpfs
  8. sudo rm -rf ramdisk*
  9. sudo losetup -d /dev/loop0
  10. sudo losetup /dev/loop0 ./fs_vexpress_1G.img

3、测试
  1. [root@vexpress ]# python3
  2. Python 3.6.0 (default, May  6 2017, 00:08:14) 
  3. [GCC 4.8.3 20140320 (prerelease)] on linux
  4. Type "help", "copyright", "credits" or "license" for more information.
  5. >>> import requests
  6. >>> 
  7. [root@vexpress ]# python2
  8. Python 2.7.13 (default, May  6 2017, 00:11:41) 
  9. [GCC 4.8.3 20140320 (prerelease)] on linux2
  10. Type "help", "copyright", "credits" or "license" for more information.
  11. >>> import requests
  12. >>>
三、编写python程序获取开关状态
get_switch.py2:
  1. #!/usr/bin/env python2
  3. import requests
  4. import time
  6. apiurl = "http://api.yeelink.net/v1.0/device/7445/sensor/405914/datapoints"
  8. apiheaders = {‘U-ApiKey‘:‘3957bd54eaddd2fda1f35841d52776d9‘}
  10. while True:
  11. 	r = requests.get(apiurl, headers=apiheaders)
  12. 	print(r.text)
  14. 	sw = r.json()
  15. 	if sw[‘value‘] == 1:
  16. 		print("Switch On")
  17. 	elif sw[‘value‘] == 0:
  18. 		print("Switch Off")
  19. 	time.sleep(2)
get_switch.py3:
  1. #!/usr/bin/env python3
  3. import requests
  4. import time
  6. apiurl = "http://api.yeelink.net/v1.0/device/7445/sensor/405914/datapoints"
  8. apiheaders = {‘U-ApiKey‘:‘3957bd54eaddd2fda1f35841d52776d9‘}
  10. while True:
  11. 	r = requests.get(apiurl, headers=apiheaders)
  12. 	print(r.text)
  14. 	sw = r.json()
  15. 	if sw[‘value‘] == 1:
  16. 		print("Switch On")
  17. 	elif sw[‘value‘] == 0:
  18. 		print("Switch Off")
  19. 	time.sleep(2)
四、测试
运行测试程序，然后在手机客户端或在网页端修改开关的状态：
