从busybox提取的ftp客户端程序，main函数是测试函数。用arm-linux-gcc ftpClient.c -o main编译后即可运行。-Busybox extracted from the ftp client program, main function is to test the function. Use arm-linux-gcc ftpClient.c-o main compiled to run.

PIC690做的控制板，有IIC模块，有串口模块，适合初学单片机的同学们做参考，也适合工程师直接调用内部封装的函数，省去了很多不必要的麻烦。如果有更好的请大家一起分享。

This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO. -This model is just an idea of testing MIMO. IEEE802.11n which will have. But I havo not seen the standard.

超声波模块HC-SR04,MCU ATmega16，不是通过中断实现。MCU先发一个使能信号，然后检测回波信号高电平的时间，通过串口显示。实际测试精确度很高。
