我看过很多PT2262软件解码程序，都是用定时器测量脉冲宽度。占用系统太多资源。我自己编写的程序不用定时器，不用中断，代码最少。发射端为PT2262 3.3M 的电阻 接收端为 M8 内部1M RC振荡。解码成功后输出D口显示。编译软件为 ICCAVR。 -I have seen many PT2262 software decoding process, are used timer measures the pulse width. Takes too much system resources. I have written a program without timers, without interruption, the code minimum. Transmitter for the PT2262 3.3M resistor receiving end for the M8 internal 1M RC oscillation. After successfully decoded output port D display. Compile software ICCAVR.
