串行A/D、D/A转换器与89C51单片机的接口设计

Interface Design of Serial A/D Converter and Serial D/A Conveter for 89C51 Single-chip Microcomputer

介绍串行A/D转换器MAX186的数据采集过程及串行D/A转换器TLC5615的控制输出过程,并叙述了上述两种芯片与MCS-51单片机在同一系统中的接口技术及软件设计原理和实现细节。

This paper introduces data sampling of the serial A/D converter MAX186 and the working process of the serial D/A converter TLC5615. The application of their interface circuit with 89C51 in the same system are demonstrated, both in hardware and software.
