毕业论文：基于单片机的LED点阵显示屏设计。 跪求啊~~~ 有出处也行，只有能过。

一、毕业论文（设计）的主要内容
1. 提出基于单片机的LED点阵显示屏设计的系统构成框图，设计出单元电路和整体电路。系统实现的功能要求：
（1）用8×8点阵屏构成若干个显示汉字的32×32点阵；
（2）利用上位机PC机编写显示的汉字和图形，传送给下位机单片机显示汉字或图形；如安徽农业大学工学院欢迎您、钟表等；
（3）显示效果如拉幕、流水、定格等。
2. 完成合理选择好MCU芯片和相应的元件。
3. 完成MCU芯片的应用程序设计。
4. 设计出下位机MCU控制电路的PCB印制图，完成相应的功能模拟实验、做出样机调试，。
5. 完成撰写6000 ~ 8000字左右的毕业论文。
