提出了对包装跌落冲击信号的快速,高效数据采集方法及其实现原理,通过设置“采样开始”和“采样结束”控制信号来实现对跌落冲击信号的准确捕捉;采用DMA方式实现内存和外设间数据的快速递。
A fast and efficient data acquisition method and its realization principle for drop impact signal of package are proposed. The accurate capture of drop impact signal is achieved by setting the control signals of “sample start” and “sample end”. The DMA and memory Quick delivery of data between.
