【摘要】 为了满足数据采集的高速、高精度要求,提出16 bit A/D转换器LTC1606与LPC2210结合使用的方案。分析了LTC1606的基本特性与其A/D转换的两种工作模式,探讨以LPC2210作为系统主控芯片来控制LTC1606的采集和A/D转换的硬件接口电路设计;软件设计采用中断方式来处理采集到的数据,并给出了部分程序代码。经实践证明,应用在高速测量、CCD图像采集系统中处理效果良好。更多还原

【Abstract】 The project of 16 bit A/D converter LTC1606 and LPC2110 is presented for meeting with the high-speed and high-precision of acquisition data.The basic characteristic of LTC1606 and two working modes of its A/D converter are analyzed,design of hardware interfaces circuit are discussed,which acquisition data and A/D convert of LTC1606 is controlled by LPC2110;dealing with the acquired data via interrupt method is used in design of software,and part of program are offered.With practice,the effect is finer apply the system to high-speed measure and system of acquiring CCD framing.更多还原
