eo2c5 实现 led 键盘控制 verilog 编程

单片机,嵌入式系统实时操作系统rtos及基于80C51单片机源码 -Single chip, embedded systems and real-time operating system rtos source based on 80C51 microcontroller

显示了键盘消息的顺序,所有键盘消息都被捕获和记录在数组里，并在WM_PAINT消息里被显示出来。-Shows the sequence of keyboard messages, all keyboard messages are captured and recorded in the array, and where in the WM_PAINT message to be displayed.

MSC-51系列单片机内有128B或256B的RAM数据存储器，对一般应用场合，内部 RAM可以满 足系统对数据存储器的要求，但对需要大容量数据缓冲器的应用系统（如数据采集系统），仅片内的RAM存储器往往不够用，这种情况下，就需要在单片机外部扩展数据存储器。 MSC-51与外部数据存储器的一般连接方法：外部数据存储器的高8位地址由P2口提供，低8位地址线接地址锁存器的输出端。外部RAM的读、写控制信号分别接MCS-51的 、 。外部RAM的片选信号可由P2口未用的地址线的剩余口线以线选方式或译码方式提供。 随机存贮芯片（RAM）HM62256的存贮量为32KB，地址线有(A0～A14)，是单片机应用系统中最常见的数据存储器 -err

５１单片机开发的键盘扫描程序　希望对大家有用-Development of 51 single-chip microcomputer keyboard scanner hope useful for everyone

51系列单片机的串口测试源码，经过项目验证可以直接放心使用，用c写成-51 Series MCU serial testing source, after the project can be directly verified to worry about, written with c

设计的主要内容如下 （1）设计一款电子秤，用LED液晶显示器显示被称物体的质量 （2）可以设定该秤所称的上限 （3）当物体超重时，能自动报警 （4）写出详细的实验报告 -The design of the main contents are as follows (1) the design of an electronic scale, liquid crystal display with LED shows that the quality of objects (2) can set the scale referred to as the upper limit (3) When the objects are overweight, they can auto-alarm (4) write a detailed experimental report

基于51单片机实现的M序列发生器（伪随机序列），在Keil编程环境下的源码-Based on 51 single-chip realization of M sequence generator (pseudo-random sequence), in Keil of-source programming environment

一个PIC的demo程序包，供给初学PIC者快速上手的资料-a demo package, the supply of learning PIC were unfamiliar information

一个用C51编写的倒计时程序，可通过PC传送起始时间，也可回传当前时间。比较简单-C51 with a countdown of the preparation process, through PCs starting time, but also back- the present time. Relatively simple

这是一个关于秒表倒计时的程序，写的很经典，拿来就可以用-It is a countdown on the stopwatch program, written in a very classic, brought can use
