汇编子程序 大学课程设计需求者的最爱-compilation subroutine university curriculum design needs a favorite

我刚写好的，已调试成功，HT1621的汇编和一键多功能的汇编。-I have just written has been successfully debug, HT1621 one compilation and the compilation of multi-function keys.

本程序是一个用汇编编的精致的图形时钟，运行时双击clock图标即可，钟表显示的时间为本机系统的时间。　　按b键可扩大画面 ；按s键可缩小画面；按c键可改变颜色；按e键可听音乐；按q键退出本程序.-this program is compiled using a series of intricate graphics clock, double-click the clock running icon, watches showed the time-based system of the machine. By b Bond picture can be expanded; According s keys can narrow picture; By c Bond can change color; By e keys to listen to music; Q keys on the withdrawal procedures.

用8251a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，中断方式接受。自收结果显示于屏幕。按esc返回dos -8251a Serial port with asynchronous communication, spontaneous self-income, the baud rate 1200bps, using queries sent, interrupt to receive treatment. Since the close results showed on the screen. Press esc to return dos

这是用MCUAT89C2051控制切换芯片MT8816,8路输入,16路输出的视频切换源程序-MCUAT89C2051 control switch chip MT8816, eight road input, 16 output video source switching

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 -Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.
