脉冲记时CPLD
- 工作原理: 脉冲输入,记录30个脉冲的间隔时间(总时间),LED显示出来,牵涉到数码管的轮流点亮,以及LED的码。输入端口一定要用个 74LS14整一下,图上没有。数码管使用共阴数码管。MAXPLUS编译。 测试时将光电门的信号端一块连接到J2口的第三管脚,同时第一管脚为地,应该与光电门的地连接(共地)。 开始测试: 按下按键,应该可以见到LED被点亮,指示可以开始转动转动惯量盘,等遮光片遮挡30次光电门后, LED熄灭,数码管有数字显示,此为时间值,单位为秒,与智
4x4KEY
- 首先将下载板插到主板上面. 1。源文件保存在src目录,QII的工程文件保存在Proj目录; 2。程序实现的功能测试4×4键盘按键;具体的键值通过板上的数码管来显示。按下K1就显示1,K2就显示2.用户可以试试. 3。具体设计参考代码。
