用AT89S51单片机软件解码PT2262，编码芯片PT2262发出的编码由：地址码、数据码、同步码组成。地址码和数据码都用宽度不同的脉冲来表示，两个窄脉冲表示“0”；两个宽脉冲表示“1”； F” 一个窄脉冲和一个宽脉冲表示“,也就是地址码的“悬空”；同步码为时间较长的低电平间隔-AT89S51 MCU with software decoding PT2262, encoding chips PT2262 code issued by: address code, data code, synchronization code form. Address code and data codes are used to represent the pulse width of a different, two narrow pulses, said, " 0"　 two wide pulses, said " 1"　 F " a narrow pulse and a pulse width, said,"　that is, address code "　Suspended "　 synchronization code is a longer time interval of the low
