西南科技大学本科生毕业论文 PAGE \* MERGEFORMAT IV 基于ATMEGA16的新型家用智能化闹钟电路设计 摘要：本文首先描述系统硬件工作原理，并附以系统结构框图加以说明，着重介绍了本系统所应用的各硬件接口技术和各接口模块的功能及工作过程。其次，详细阐述了程序的各个模块和实现过程。本设计以数字集成电路为基础，单片机技术为核心。本文撰写的主导思想是软硬件相结合，以硬件为基础来进行各个功能模块的编写。 本系统以AVR系列单片机Atmega16为控制核心，以实时时钟DS1302对年、月、日、周、时、分、秒进行计时，以温度传感器DS18B20测量测温度。同时用C语言进行软件设计，增加了程序的读可性和可移植性。系统通过LCD显示数据，通过键盘进行人机交互。所以具有人性化的操作和美观效果。模块化设计和调试方法在整个课题研究过程中至关重要，事实上在任何设计中也同样关键和有效。 关键词：智能闹钟；仿真；单片机；硬件设计；软件设计 New type of household intelligent alarm clock circuit design based on ATMEGA16 Abstract: This article will first describe the working principle of the system hardware with the system block diagram to illustrate the structure, highlighted by the application of the system interface technology of the hardware and the interface module functions and work processes. And secondly, the procedures described in detail the various modules and realization of process. The design of digital integrated circuits technology takes single-chip technology as the core. This article is the guiding philosophy of preparation of a combination of hardware and software to hardware-based, to the preparation of various functional modules. ATMEGA16 in the system for the control of single-chip core to real-time clock circuitry on the DS1302 year, month, day, weekdays, hours, minutes, seconds for time, also has multiple functions, such as a leap year compensation, at the same time with C language software design, increase the readability and probability procedures. LCD display date through the system and therefore have a user-friendly operation and aesthetic results. Modularized design and debug are most important in the whole course of the topic research. In fact, it is as well as vital and effective in any other design course.
