Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorre

适用于AT89C2051的基于2.4G频段NRF24L01无线射频通信程序，通俗易懂，值得借鉴！-Applicable to the AT89C2051 based on NRF24L01 radio frequency band 2.4 G, understandable, communication program is worth using for reference!

利用Labview写的简易串口程序,G绘图简易-Use Labview to write a simple serial program, G simple drawing

DXF轨迹图转G代码，有 直线，圆，圆弧，样条曲线，优化多段线，多段线。与下位机串口通讯！无法编译，是因为要先注册mscomm控件-DXF trajectories turn the G-code, line, circle, arc, spline curves to optimize the polyline, polyline. With lower serial communications! Not compile because the first registered mscomm
