嵌入式课程设计电子词典硬件设计说明

上海电力学院嵌入式系统课程设计报告题目：电子词典的设计姓名：学号：院系：专业年级：同组成员：年月日一、实验内容及要求在LCD屏幕左侧绘制出单词输入框和释义显示框以及一个搜索键，右侧绘制4*4键盘按钮，模拟出简易电子词典的功能，按钮操作用触摸屏或键盘实现均可。

实现功能：（1）LCD屏幕上显示4*4键盘，显示单词及其翻译、例句。

（2）一个键可完成2个英文字母的输入，如左上角第一个键可实现输入a,b两个字母，第一次按下时为输入a，如果需输入b，只需连续快速按键两次即可。

（3）在输入完单词后，点击搜索键，即可在释义显示框中显示该单词的词性、中文解释、示例词组和句子等。

（4）当发现输入的单词在库中不存在时，可实现将该单词添加入库的操作。

二、设计思路（1）通过LCD显示模块画出电子词典操作界面。

（2）对应界面中各键的位置设置键盘对应键值。

（3）设定功能键，实现以下3个功能：①退格键：删除最后一位字母；②搜索∕保存键：对输入框的单词进行判断，若单词存在于词库中，则显示单词词性、词义、例句；若单词不存在则自动进行保存；③转换键：按下后，字母键输出对应的第二个字母。

（4）按键后赋值并显示。
