通过51单片机设计一个电子时钟，精确到秒，可以通过按键调节时间(By 51 microcontroller design an electronic clock, accurate to seconds, you can adjust the time by pressing a button)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

1.可以自动生成十六进制字编码。 2.可以自动C语言格式字符编码。 3.支持GBK和ASCII字符编码查询。(1 can automatically generate a hexadecimal character encoding. 2 can automatically format the C language character encoding. 3 support GBK and ASCII character encoding query.撤消修改)

定时器：设定时间格式（00：:00）后，到时间弹出提示(timer：set time(00:00),then run up)
