基于SPI总线的高精度数据采集器

High Accuracy Data ollector Based on SPIBus

介绍了采用TLC2543C串行A/D转换芯片设计的一种基于SPI总线的数据采集器 ,并给出了TLC2543C的工作时序和采集器的软件流程图。该采集器应用在温度测试、压力测试、环境参数监控等测试监控仪器仪表中 ,具有分辨率高。

This paper introduces a data collector based on SPI bus which applies TLC2543C serial A/D conversion chip and gives out the timing diagram of TLC2543C and the flow chart of the collector. This collector can be directly applied in temperature test, high sampling stabilization and enlargement pliancy.
