时钟程序,PCF8563时钟芯片程序，基于单片机开发环境-clock

51控制led顺序点亮, 通过控制p0.0使其能按不同的顺序 -Led the order of 51 to control light, through the control to enable them to p0.0 different order

该程序采用汇编语言完成，基于AT89C51adc0809和LCD1602实现数字电压表-The procedure used to complete assembly language, based on the LCD1602 realize AT89C51adc0809 and digital voltage meter

配合单片机I/O口，实现单片机对LCD1602的简单控制，从而实现液晶显示（包括图像显示）的功能。-With single-chip I/O port, to achieve single-chip LCD1602 simple to control, in order to achieve liquid crystal display (including image display) functions.

一个C style Assembler的source code-one of the C style Assembler source code

This a assembly languages that teach how to write floppy disk subroutine. A great start for beginner who want to learn how ASM work. i got 100 for this assignment. have a look and comment-This is a assembly languages that teach how to write floppy disk subroutine.

用汇编语言实现的可以播放歌曲的是程序，在51单片机上配合蜂鸣器可以播放梁祝的歌曲。-Using assembly language to achieve that can play songs that procedure, in 51 single-chip buzzer can play with the song Butterfly Lovers.

详见压缩文件，关于屏幕窗口程序的汇编语言-See compressed file, a window on the screen of the assembly language program

TLC2543是TI公司的12位串行模数转换器，使用开关电容逐次逼近技术完成A/D转换过程。由于是串行输入结构，能够节省51系列单片机I/O资源；且价格适中，分辨率较高，因此在仪器仪表中有较为广泛的应用。-TLC2543 is TI s 12-bit serial ADC, the use of switched-capacitor successive approximation technique to complete A/D conversion process. Because it is serial input structure, and can save 51 Series single-chip I/O resources and affordable, higher resolution, so the instrumentation are more widely used.
