基于Atmega16L的高精度频率调节器
1 引言 在现代化工业生产与高精度测试中，我们需要相当精确的频率来帮助判断设备性能指标。而且我们希望能够微调该频率。采用压控振荡器得到的频率不够精确，微调频率步骤烦琐，耗时漫长，因此有些测试项目限制了压控振荡器的使用。 Mega系列单片机是Atmel公司于2002年起陆续推出的。这款AVR增强型单片机具有速度快，抗干扰能力强，价格低廉等诸多优点。为了加快AVR单片机的软件编制，Atmel以及第三方提供的开发工具多种多样，程序开发方便有效。该单片机内部FLASH结构功能灵活，加锁后很难解密，可以最大限度地保护知识产权。AVR单片机可以广泛应用于通信、野外测试、汽车电子、医疗器械等领域，并且适用于各种低电压、低功耗的场合。 本
