本文将在前面mini2440建立的domoticz、mosquitto为服务器的基础上，以Android做远程客户端来实现对STM32芯片的开发板的LED进行灯控制，当然，这是一个基本功能的实现，如果长期使用的话，还需要做很多其他的工作（例如断网重连，重连多少次重启系统等等，还要有个可以在SD卡上读入的硬件配置信息等等）。
首先展示一下开发板这边情况，硬件方面是在2011年买的“金牛开发板”，主控芯片是STM32F107VC，PHY芯片是DP83848，烧固件的工具是随开发板带来的Jlink，从JTAG口烧录进去。
软件方面，使用RTThread-2.1.0作为操作系统，该系统自带移植的嵌入式TCP/IP协议栈LwIP。
本文中使用的LwIP协议栈版本是1.4.1，是rtthread默认bsp中默认的版本。
bsp工程文件位置：rt-thread\bsp\stm32f107\project.uvproj
bsp已经实现了PHY芯片DP83848的驱动，所以就省了很多事。
使用的集成开发环境是：MDK 4.11 版本
本人在工程中是用了对c99的支持（主要是为了调试）。
本来看介绍，还以为RTThread-2.1.0已经移植好了MQTT客户端程序，但实际上，只是把代码放过来，还没有做什么移植。
所以，要实现本文的目标，就需要对MQTT客户端做个移植。
mqtt的客户端程序在rtthread软件包的位置是：
rt-thread\components\external\paho-mqtt
不知道这个是什么版本的，总之，本人是用在mini2440上已经验证过的版本，就是官方在GitHub上的最新版本，封包解包的那部分用MQTTPacket，可以不用改动，直接就用。
MQTTClient-C这个模块部分，用自己的实现。
放到rt-thread\components\external\paho-mqtt\MQTTClient-C\samples\domoticz目录下。
主要实现有三个部分：
1、对socket的读写的基本操作简单封装。相关内容放到MQTTRTThread.h和MQTTRTThread.c中。
2、对MQTT连接和消息的解析详细过程。相关内容放到MQTTClient.h和MQTTClient.c中。
3、对整个过程的控制，使用rtthread的一个线程实现。相关内容放到DomoticzThread.h和DomoticzThread.c中。
源码放在后面附上。
接下来要说的内容就是把曾在mini2440上用过的domoticz消息解析框架移植过来。
果然keil的arm编译器跟GCC是不同的，要做一些改动。改好的源码在后面附上。
这一部分放在rt-thread\bsp\stm32f107\applications目录下。
在STM32开发板上，也控制了两个LED作为例程。
效果跟mini2440上的是一样的，以后有时间再上图吧。
后面有时间把整个工程打包上传上来。
