[其他书籍] IR

本文以AVR系列中高性价比的Atmage8为例,利用16位时钟单元T/C1的捕获中断来实现红外线解码。T/C1内部的输入捕获单元可以应用于精确捕获外部发生的事情,亦即事件发生的时间印记(time-stamp)。当一个输入捕获事件发生在外部引脚ICPI上的逻辑电平也随之发生变化时,T/C1的计数值将被拷贝到捕获寄存器ICR1并设置捕获中断标志,如果捕获中断允许并且总中断IE打开,系统则进入中断服务程序。这种捕获中断通常用于频率和周期的精确测量,如电机转速和转向的测量。本文介绍怎样利用这一功能测量红外线脉冲的脉宽以实现红外传输的解码。捕获中断的触发可以是ICP1引脚上电平变化的上升沿,也可以是下降沿。根据前述脉冲调制规则,现以下降沿为触发事件来进行讨论。
