红外报警！示波器显示接收数据与发送数据一致，但就是不能进行报警？（附源程序）
红外报警的原理是参照该网站范例，不过，由于我现在用的是汇编，所以只能自己按照的思路编程了！但现在却不能报警！查了几天也没有查出个结果来，搞得很是郁闷！报警原理：正常情况下，蜂鸣器不响，红色LED不亮，绿色LED亮，当有障碍物时，绿色LED熄灭，红色LED亮起，同时蜂鸣器响十次。之后恢复正常情况。如此循环！

reti SPH=？ 我看了2313的PDF文档，不需要使用SPH的。
我今天重新看了仔细再了一篇程序，发现在一些问题，但还还是没有取得实质性的进展！
程序作了修改如下：

rjmp ir_receiver_check 看不懂汇编 硬件是什么样的？那个网站？ 硬件电路比较上是参照该网站上的那个范例，不过，网站上的那个是用M8，而我现在是采用ATTINY2313的，红外发射引脚是PD4，红外接收引脚是PD2，红色LED是接PD0的引脚，绿色LED是接PD1的引脚，蜂鸣器是接PD5引脚。
我现在怀疑是不是因为在延时期间（850us的延时）与定时器0溢出产生中断相冲突？ 今晚再查看该程序，再次作了部分的修改，但还是没有取得实质性的进展！搞得郁闷死了！
修改程序如下：
