SPI总线驱动程序 包括的普通封装标准模式,特殊封装标准模式 。

基于51单片机,用C语言实现MAX186/MAX188数据采集和通信！ 包括C程序代码和硬件连接图！

基于adc0809的ad转换c51程序，大家参考下~~~~~

这是一个实验指导 主要是利用c51编制一个可以通过按键播放音乐的程序

程序效果：单片机模拟控制交通灯程序，规则如下：当南北通车时，此时南北的绿灯亮，东西的红灯亮，之后南北的绿灯闪烁3次，过后黄灯亮，延时片刻，转东西绿灯亮同时南北红灯亮，之后东西的绿灯闪烁3次，过后黄灯亮，延时片刻；数码管显示的值都同步，结束。

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。
