在C51下编写的频率计函数，可以对测得输入信号的频率

使用AVR单片机 codevision C语言实现的pt2272解码。目前网络上类似代码基本上是使用51系列单片机加汇编语言完成的，可移植性比较差。-codevision AVR using C language pt2272 the decoder. Currently the network code is basically similar to the use of 51 series microcontroller plus the completion of assembly language, portability are relatively poor.
