1、用8255的A口驱动六个七段数码管（LED）的字段，C口驱动六位七段数码管（LED）的位控端，右侧两位显示分值，左侧两位显示秒值。 2、段数码管采用动态扫描方式，用8253做定时器（采用查询方式），每位显示的时间50Hz。 3、以5ms为基本时间单位，计数产生秒时间值，秒计数到60时对分计数，分计数到69时对时计数。 -BUFF_KEY EQU 21H BUFF_LED1 EQU 22H BUFF_LED2 EQU 23H BUFF_LED3 EQU 24H BUFF_LED4 EQU 25H BUFF_LED5 EQU 26H BUFF_LED6

本次设计的RS232 to USB转换器，RS232端所采用的baud rate仅为9600。并没有对其它baud rate 到 USB 作转换-The design of the RS232 to USB converter, RS232 terminal baud rate used in 9600 only. There is no other baud rate to USB conversion

串口调试程序很划算哦的 杜可风上的饭-Serial debugger

配置visual_studio_2005和visual_studio _008汇编程序。采用INtel_A2-Configure visual studio 2005 and visual studio 2008 assembler. Using INtel_A2

还是一个asm编的VXD例子-asm or a series of examples VXD

DS1620/8051显示器

用8251实现串行口异步通信，自发自收，波特率1200bps。采用查询方式发送与接收。从键盘输入发送字符。发送与接收的字符均在屏幕上显示。按esc键返回dos-Achieved with the 8251 serial asynchronous communication, spontaneous self-income, the baud rate 1200bps. Way to send and receive using queries. To send characters from the keyboard. Send and receive characters are displayed on the screen. Press esc key to return to dos

调试通过了的基于89S51的1602液晶显示的程序-Debug adopted 89S51-based liquid crystal display of the 1602 procedure

我搜索了这个网站，见提供的CD player都是 c++,delphi源程序的；我就提供一个用win32汇编写的CD player。功能跟界面绝对不输于用上面软件编写的，具体功能如下： 1. CD loop. 2. Track loop. 3. Random track play. 4. Track sample. 5. Play list. 6. Track select. 7. Master volume control. 8. CD Speaker volume controls. 9. Multiple CD drive support. -search of this site, see the CD player are c, delphi source; I will provide a written using win32 compilation CD player. Functional interface with absolutely no losers in the software used to prepare the above, the specific functions as follows : 1. CD loop. 2. Track loop. 3. Random track play. 4 . Track sample. 5. Play list. 6. Track select. 7. Master volume control. 8. Speaker volume CD con trols. 9. Multiple CD drive support.

该程序是用来动态增减窗体上的控件的.方便在不同情况使用时去掉一些控件-that the procedure was used to dynamic changes in the Form of Control. Facilitate the use of different circumstances remove some controls ..
