利用Python读取串口数据并发送到远程服务器

好久没更新了，拿出点前段东西写的东西发出来吧。硬件是用的树莓派，系统是代号为Wheezy的Debian系统，树莓派的串口设置去网上搜去，一搜一大堆。python依赖包用的PySerial，包括一个主文件和一个配置文件，配置文件如下：

[HARDWARE]SERIAL_DEV=/dev/ttyAMA0BAUDRATE=9600[SEND]REMOTE_URL=http://www.maben.com.cn/test.phpDELAY=5[RECV]REMOTE_URL=http://www.maben.com.cn/index.phpDELAY=100[LOG]ENABLE=1PATH=log.txt

程序如下：

这只是个半成品，只能读取数据并发送到远程，配置文件里面留了一个接口，就是从远程读取文件，然后发送到串口，由于暂时用不到，所以没再进行补充。
