基于LPC2210的电子钟设计.doc

本 科 毕 业 设 计 论 文 题 目 基于LPC2210的电子钟设计 系 别 电气与信息工程 专 业 班 级 学 号 学生姓名 指导老师 2011年 6月 摘 要 电子钟的发展是非常迅速的，从刚开始的机械式钟表到现在普遍用到的数字式钟表小型化、多功能化校准功能HS12864-10A液晶显示屏相结合，通过独立式键盘控制时间的调节。软件设计是将RTC产生的时钟信号通过I2C高速通道经液晶的驱动T6963C对年、月、日、星期、时、分、秒显示输出。 本设计基本上完成了所要求的任务，通过按键可调整年、月、日、星期、时、分、秒的走时。这次毕业设计的制作，使本人对ADS1.2的运用更加的熟练，对LPC2210这款芯片了解的更多。 关键字：LPC2210，ARM，时钟，RTC，ADS1.2 ABSTRACT Clock is very rapid development, from the beginning of mechanical watches to digital is now widely used in watches, from the beginning of the large-type, single-function, then to the present small, multi-functional. The design of the main tasks are: the internal real time clock through LPC2210 RTC generates the clock signal displayed on the LCD screen. It can be year, month, day, weeks, hours, minutes, seconds for time, also has a calibration through the key functions of time. This topic is based on the LPC2210 electronic clock design. Hardware and software into the guidelines to give full play to the microprocessor function, and its simple circuit design, system stability, in real life to get a very wide range of applications. Hardware design is based on LPC2210 as the core controller, with HS12864-10A LCD screen, and stand-alone keyboard. Software design is the RTC generates the clock signal, through the I2C high-speed access to its data and clock for reading and feedback, and then by T6963C LCD driver on the year, month, day, weeks, hours, minutes, seconds display output. The design is basically completed the required tasks, through the button to adjust the year, month, day, week, hours, minutes, seconds travel time. The production of the graduation project, so I am more skilled use of ADS1.2 on LPC2210 chip learn more.
