51单片机入门 - IIC(I2C)总线

UART 属于异步通信，比如电脑发送给单片机，电脑只负责把数据通过TXD 发送出来即可，接收数据是单片机自己的事情。而 I2C 属于同步通信， SCL 时钟线负责收发双方的时钟节拍， SDA 数据线负责传输数据。 I2C 的发送方和接收方都以 SCL 这个时钟节拍为基准进行数据的发送和接收。 I2C总线包括SCL,SDA 两根信号线，其中SCL是时钟线，SDA是数据线。 1、起始信号 UART 通信是从一直持续的高电平出现一个低电平标志起始位；而 I2C 通信的起始信号的定义是 SCL 为高电平期间， SDA 由高电平向低电平变化产生一个下降沿，表示起始信号。 2、数据传 UART 是低位在前，高位在后；而

AT89C51单片机在LED显示屏控制电路设计中的应用

LED显示屏又叫电子显示屏,是由LED点阵组成，通过红色或绿色灯珠的亮灭来显示文字、图片、动画、视频，内容可以随时更换，通常由显示模块、控制系统及电源系统组成。显示模块由LED灯组成的点阵构成，负责发光显示;控制系统通过控制相应区域的亮灭，可以让屏幕显示文字、图片、视频等内容，恒舞动卡主要是播放动画的;电源系统负责将输入电压电流转为显示屏需要的电压电流。 LED显示屏广泛应用于信息指示灯，大屏幕显示，液晶显示的背光灯，固体照明等。本文设计一种由4个16×16点阵LED模块组成的显示屏，由单片机作控制器，平滑移动显示任意多个文字或图形符号，本电路可级联扩展实现由任意多个16×16点阵LED模块组成的显示屏。一、控制电路设计控制电

8051单片机(STC89C52)八段数码管稳定显示0 ~ 7

在轮流显示0~7程序的基础上, 将delay()函数提供的时延大幅缩小, 以达到视觉短暂的停留效果. 在该种情况下的数码管亮度和对比度较轮流显示时有一定幅度的降低. 另外, 如果想感知到动态扫描的存在, 可从拍摄视频中观察(到像波浪一样的光浪). #include STC89C5xRC.H void delay()//提供时延 { int i, j; for(i = 0; i 15 ; i++) for(j = 0; j 15; j++) ; } void f1_3_4_3()//在8个数码管上轮流显示0~7 { unsigned char code DIG_CODE = {0x3f, 0x06, 0x5b

51单片机（入门保姆级教程）——LED闪烁及流水灯

一、LED基本原理和知识图1 LED共阳极原理图 1.1 LED共阴极和共阳极的含义 LED的最小单元是发光二极管。发光二极管是区分正负极的，正向导通，反向截止。共阴极就是发光二极管的负极连接在一起，共阳极就是发光二极管的正极连接在一起。 1.2 共阴极和共阳极的区别耗能不一样。共阳极二极管的公共端接在高电平，需要高电平时时刻刻处在工作状态；而共阴极二极管公共端接低（GND），只需指定二极管工作时给某个二极管高电平即可，有效降低了功耗，对长时间工作LED来言有效降低了屏热。线路复杂程度不同。一般在实际工程中共阴极二极管比共阳极二极管的线路复杂，共阳极不需要那么多的高电平线路驱动。二、单个LED的闪烁 2.1 KEI

51单片机-多文件编写

为了与主流的编程素养接轨，我们本章讲解如何书写简洁并且高效率的代码以及首次运用多文件编程。多文件的作用是方便编写大程序时更加的模块化，那么至于原理，头文件包含关系等这些知识还需读者自己再多多补补C语言知识了。 1.多文件的优势运用多文件编程是为了使我们教程无需每次都贴出相同功能的代码，像第一阶段最后的一个例程，已经有很多代码完全可以前往以前的例程里复制即可，笔者也是考虑到一开始我们都是从单个“.c”文件入门单片机编程，所以之前的例程都是提供完整的代码给大家方便复制移植到自己的单个“.c”工程文件中。可后期的例程里我们的代码量越来越大，显然全部给出就不合适了，所以我们把经常使用的功能模块代码封装起来放在另一个“.c”文件

基于nRF905模块和51单片机的无线收发系统设计

前言在闭环钻井系统中，要求实时地把井下的信息传递到地面，以实施人工监控。通常情况下该任务由MWD中泥浆压力脉冲发生器来完成。当使用井下动力钻具组合时，近钻头传感器和MWD被动力钻具隔开。传感器无法用线缆与MWD连接，因此要把传感器的信息传送给MWD只能通过无线通信的方法。本文设计了由C8051F0606单片机和nRF905无线射频器收发组成的一种无线数据传输系统的方案。该系统由发射和接收模块组成，发射模块主要将要发送的数据经单片机处理后，通过nRF905发送出去；在接收模块中，nRF905则将数据正确接收后通过上位机界面显示出来，从而实现短距离井下的无线通信。无线收发系统硬件设计 nRF905模块简介 nRF905是Nord
