C51单片机 一个简单的时钟程序(适合初学者，没加调校功能，包括了原理图和源程序）

c语言编写的51数字时钟程序，含protues仿真，用8位数码管显示，小时—分钟—秒之间一杠可以闪烁，调时间时相对应的位也会闪烁

1. 用16盏以上的LED小灯，实现至少4种彩灯灯光效果（不含全部点亮，全部熄灭）； 2. 可以用输入按钮在几种灯光效果间切换； 3. 可以通过按钮暂停彩灯效果，使小灯全亮，再次按下相同按钮后继续之前的效果； 4. 增加自动在几种效果间切换的功能，并设置一个按钮可以在自动模式和手动模式间切换； 5. 使用定时中断延时。 程序中实现了十钟灯光效果，分别是： 顺时针流水灯、逆时针流水灯、交替闪烁、顺时针对角灯、逆时针对角灯、顺时针逐个点亮、顺时针逐个熄灭、逆时针逐个点亮、逆时针逐个熄灭、二进制加法。

DS1820串口测温C51详解程序

对射式红外计数器，可实现对车位数等的计数，本实验中采用LCD1602液晶显示，采用查询方式进行计数。

Keil C51最新版注册机,已测试可用，使用期限到2025年。

简单的单片机交通灯 包含程序+proteus仿真 系统实现的功能：系统电路上电后 (一)东西方向显示绿灯时，南北方向显示红灯，持续20秒钟后，绿灯变为黄灯并持续3秒钟； （二）然后东西方向显示红灯，南北方向显示绿灯，持续20秒钟后，绿灯变黄灯并持续3秒钟，然后循环反复。

最全80C51汇编指令集，还有详细介绍工作模式。

在串行口方式1（波特率为1200）下降数据1、2、3、4、5、6、7、8分别从一单片机发送到另一单片机，接收单片机在P1口输出接收到的数据，并用端口的LED小灯显示数据，灯亮为逻辑0，灯灭为逻辑1。
