摘要
本文介绍用89C51单片微机控制直接数字频率合成器(DDS)芯片AD9835设计的高精度多种信号发生器,着重讨论了AD9835基本工作原理、与89C51接口,单片微机控制系统的硬件结构及软件设计框图。
This paper introduced one kind of multi-signal generator based on DDS chip AD9835 and derectly controled by MCU. The general working theory of AD9835 and the interface with 89C51, including the hardware structure and sofeware design flow chart are mostly presented.
