pov单片机

⑴ 跪求直流电机恒速控制电路图和程序，我做的POV LED恒速屏毕业设计，就差直流电机恒速了

你妈 的 这都 不懂 还上学干什么呀 父母花钱就是让你干这个的

⑵ 单片机做pov显示时钟，转速过快会有问题吗

ds1302时钟芯片是不断地读取内部数据送到外部显示的，
仿真的时候用的是系统时间，
如果出现时快时慢，要么是CPU负载100％卡了，要么就是你的显示程序不合理，显示程序没有实时地反应秒的状态。我以前做的都没这情况。显示刷新专门放在一个定时器里定时刷新

⑶ 拿51单片机可以做什么简单逼格高的小东西.不想

用一个16*16点阵模块做个俄罗斯方块游戏机，或者用两个点阵，搞一表白墙。

⑷ POV啥意思

好像是视觉暂留的意思，有好多关于POV的单片机趣味实验，不知道是不是你想要的答案！！

⑸ 《51单片机POV趣味制作详解》哪有卖的

在卓越亚马逊上面好像有，这本书真的很不错哦，我从学校的图书馆借了一个多月，都舍不得还，貌似我还有这本书的源程序，电子档的

⑹ 请单片机编程高手帮帮忙！！！ （1） 制作一个由16只 LED构成的线状点阵及其控制电路，安装于可旋转的平台

在网上搜POV LED ，很多人在做，淘宝也有卖

⑺ pic 16f877a 头文件

也就汇编的头文件PIC16F877A.inc和C语言的pic1687x.h这两种文件。
想要找汇编的头文件，只要你的电脑装了MPLAB就行，直接在MPLAB的安装目录下找即可，比如我的MPLAB7.50是装在D盘的，我要找这个汇编的头文件就是在D:\Program Files\Microchip\MPASM Suite这个目录里。 而PIC单片机官方没有出针对PIC16F877A的C语言编译器，一般很多人都用PICC编译器，我电脑上的PICC8.50也装在D盘，D:\HT-PIC\include下找就行pic1687x.h
