摘要
本文介绍了由AVR单片机ATmega8控制DDS芯片AD9832开发的一种高频率精度信号发生器,着重讨论了DDS技术的基本工作原理、特点,以及ATmega8控制系统的硬件结构和基于BASCOM-AVR的软件设计流程图。此外,还对ATmega8和BASCOM-AVR的特点进行了介绍。
In this paper, a kind of high precision frequency signal generator based on DDS chip AD9832 and controlled by AVR MCU ATmega8 is introduced. The general working theory of DDS technology and its characteristics, including the hardware structure of the ATmega8 controlled system and the software design flow chart based on BASCOM-AVR, are discussed. What＇ s more, the features of ATmega8 and BASCOM-AVR are also presented.
