描述了用汇编语言对dm512信号接受与处理的过程，实现对led灯光控制。-Describes the assembly language used on the dm512 signal acceptance and treatment process, led lighting control to realize.

简单的汇编语言虚拟机,可以编译并执得很简单的汇编语言程序-a simple virtual machine that can execute a simple assembly language

DS1302的驱动程序，C51编的，最后由proteus仿真的，可以显示设定时间，程序中的延时函数是由汇编语言实现，也就是说这程序是C和汇编混编的。-DS1302 driver, C51 series, and finally by the Proteus simulation can show the set time delay proceedings by the assembly language function is to achieve, that is to say that the procedure is of mixed C and assembler.

基于51单片机的带时间显示和紧急控制的交通灯的设计。 此程序在硬件上调试通，用定时器1延时，外部中断0接紧急控制，R0为100MS延时常数，R2为状态延时常数，8279控制数码管显示时间,用P1口控制双色灯-With 51 single-chip based on the time display and the emergency control of traffic lights design. On this process in hardware debugging pass, with one delay timer, external interrupt 0 then the emergency control, R0 for 100MS constant delay, R2 for a state of constant delay, digital 8279 control display time control using two-color lights I P1

这个程序设置非常简单，但它已包含最常用的功能.-this program is very simple, but it contains the most commonly used functions.

实现高级电子琴的程序，并实现若干扩展功能。 基本功能：用8257键盘输入对应的七个音阶，通过实验箱的喇叭发出声音，并通过七段数码管显示输入音阶； 扩展功能：1、录音：记录所弹奏曲目 2、放录音：任意时刻重放最新记录曲目 3、在程序中可预设一曲目，按一键实现播放该曲目。 4、在播放录制曲目或预设曲目时，按8279键盘上任意键可以暂停播放，再按一次从暂停处继续播放。 5、程序运行时有友好的用户介面 -Realize high-level organ of the process and realize a number of extensions. Basic functions: keyboard 8257 corresponds with the seven scale, through experimental sound speaker boxes, and through Seven-Segment LED display input scale the expansion of functions: one, sound recording: Record the playing pieces 2, released recordings: any time replay music 3-to-date records, in the proceedings may be the default one track, according to realize one key to play the tracks. 4, recording tracks in the player or the default program, press any key on the keyboard 8279 can pause playback, press once again to continue from the suspended players. 5, is running friendly user interface
