2、机应用系统的总体方案的设计；2单片机应用系统的硬件设计；3单片机应用系统的软件程序设计；4单片机开发系统的应用和调试能力2、课程设计题目和实现目标本次课程设计的题目是；制作一个波形发生器，产生单极性、幅度可调、周期可调的方波、锯齿波、三角波、正弦波信号，不同波形用不同符号显示在一个LED上，用一个 LCD显示幅值和频率。本次课程设计的目标：设计一个波形发生器，带有四个按钮，分别是波形选择、增加频率、减少频率、调节幅度，并带有一个LCD和一个 LED，LED用来显示波形的符号LCD用来显示频率、幅值。波形符号用1 表示正弦波，2 表示三角波，3 表示方波，4 表示锯齿波。频率的调节幅度是10HZ
3、，幅值调节幅度分别是0.2V，0.02V,0.3V,0.4V。3、设计方案本次设计采用 AT89C51 及其外围扩展系统和PCF8591，软件方面主要是应用C语言设计1/20 程序。系统以 AT89C51 为核心，配置相应的外设及接口电路，用Keil C 及 Proteus等软件开发，用 C 语言编程，组成一个多功能信号发生器。用户通过按键选择输出实验室中经常使用到的几种基本波形：方波、锯齿波、正弦波和三角波。方波由AT89C51单片机将最大值和最小值输出给进行转换，并由用户通过键盘选择波形周期。可采用单片机程序产生以上4 种波形，并通过一片转换器输出。另外，采用一片转换器来控制前一片A 转换
4、器的参考电压，从而可以改变输出波形幅值。通过外接键盘来设定波形的类型、幅值和频率。总体方案结构图a.单片机的选择AT89C51 是美国 ATMEL 公司生产的低电压、高性能CMOS8 位单片机，片内含 4Kbytes 的可反复擦写的只读程序存储器PEROM）和 128bytes的随机抽取数据存储器 RAM），器件采用ATMEL 公司的高密度、非易失性存储技术生产。兼容标准MCS-51 指令系统，片内置通用8 位中央处理器 CPU）和 Flash存储单元，功能强大。AT89C51 单片机可为您提供许多高性价比的应用场合，可灵活应用于各种控制领域。AT89C51 提供以下标准功能：4K 字节 Fl
5、ash 闪速存储器，128 字节内部RAM，32个 I/O 口线，两个 16 位定时/计数器，一个5 向量两级中断结构，一个全双工串行通信口，片内振荡器及时钟电路。同时，AT89C51 可降至 0Hz 的静态逻辑操作，并支持两种软件可选的节电工作方式。空闲工作方式停止CPU的工作，但允许RAM，定时器/计数器串口通信及中断系统继续工作，掉电方式保存 RAM 中的内容，但振荡器停止工作并禁止其它所有部件工作直到下一个硬件复位。文档编码:CY4J2C7A1C10 HE3R10T1P6V5 ZO5O6O2U1A10文档编码:CY4J2C7A1C10 HE3R10T1P6V5 ZO5O6O2U1A10
