本文介绍了冲击碰撞数据采集处理仪的硬件和软件设计。其中着重阐述了以普通、廉价的 DAC 等芯片实现高速 A/D 转换和用 DMA 方式实现高速数据传送,以及实现信号予触发的方法。本文还介绍了用状态变量法设计监控程序。
This article describes the hardware and software design of the Impact Collision Data Acquisition and Processing Instrument. Which focuses on the ordinary, cheap DAC and other chips to achieve high-speed A / D conversion and the use of DMA to achieve high-speed data transfer, and signal to trigger the method. This article also describes the design of monitoring procedures using state variables.
