PIC16F877单片机使用外部中断最简单的演示程序，适合PIC单片机初学者使用。...

服务端一方面对图像进行采集压缩传送，另一方面接受网络传送过来的运动控制指令。客户端一方面负责接受图像数据，并解压后显示，另一方面发送用户界面操作所产生的运动遥控信息。

Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.
