各色各样的霓虹灯汇编源程序和exe执行程序

用 AT89S51 单片机的定时 / 计数器 T0 产生一秒的定时时间，作为秒计数时间，当一秒产生时，秒计数加 1 ，秒计数到 60 时，自动从 0 开始。-with AT89S51 SCM timer/counter T0 produce than the regular time, seconds count as a time when a second time when, seconds count plus one, count to 60 seconds, the automatic starting from 0.

密码锁， 实现密码判断，实现密码更改，实现程序正常结束，实现非软件的准确延时，输入错误3次后自动结束程序，根据操作产生的不同结果配以不同的音效 -Password lock, password realize judgment achieve password change, the end of the normal implementation process, the accurate implementation of non-software delay, enter the wrong end of 3 times after the program automatically, under the operation of the different results produced with different audio

一个很详细的电话拨号程序，利用HT9200A发送双音频信号-A very detailed telephone dial-up procedures, the use of dual-audio signals sent HT9200A

片机电子钟的计时脉冲基准是由外部晶振的频率经过12分频后提供，采用内部的定时/计数器来实现计时功能。所以，外接晶振频率精确度直接影响电子钟计时的准确性。 -Machine electronic time clock pulse baseline is by an external crystal oscillator frequency, after 12 minutes after the frequency, using an internal timer/counter to achieve the timing function. Therefore, the external crystal frequency accuracy of a direct impact on the accuracy of the electronic time clock.
