PWM

an elastic meshless efg program

该程序对4个点目标进行仿真成像，距离向采用解线频调方法进行压缩，方位向采用传统的脉冲压缩，最后获得了4个点目标的像。程序中给出了详细的参数设置，便于理解。(The program on a four point target simulation imaging, distance to the solution line frequency modulation, compression, orientation to the traditional pulse compression, and finally a four point targets like. The program gives a detailed parameter settings, easy to understand.)

好书共享-《实例解读51单片机完全学习与应用》，全实例教学，难得的好教材。(Book Share- Instance interpretation of the 51 single-chip fully learning and teaching of all examples, a rare good material.)

pic单片机对红外设备控制得一个源程序，可读性较强(Singlechip pic of infrared device control source was a highly readable)

说明：  ELM327协议解析说明手册，做OBD开发必要手册(ELM327 protocol interpretation manual)

AD数模转换程序，是设计数据采集的一个参考c语言代码(AD digital-analog conversion process, is designed as a reference data collection c language code)

AT89S52键盘程序,这是一个变频器的键盘驱动程序，简单，可靠，芯片为51单片机(one simple progrem for 51,if you like ,you can use it freely.)

采用stm32f4核心板，实现AD采集，效果很理想，可测量流量，液位(Achieving Flow Acquisition)
