Variant变量可以在COM/DCOM接口方法中传递(传入、传出)不定长结构数组,但是需要打包和解包,效率比较低。这个例子使用了size_is指定长度的方法,本是从MSDN上看到的,但是MSDN上给出的例子不够具体,所以费了些时间摸索,最后试通,给刚接触COM的朋友分享(老家伙们可以直接无视)。本例子由于是工作需要做得试验程序,因此其中存在少量冗余代码,大家注意一下就行了,还有,减少传递的参数个数时,所传递的实时(随机模拟)数据只是减了最后一个(没有减去相对应的),这个Bug不妨碍大局,因此存

红外遥控器+红外一体化接收头部分的仿真
红外线编码是数据传输和家用电器遥控常用的一种通讯方法,其实质是一种脉宽调制的串行通讯。家电遥控
中常用的红外线编码电路有μPD6121G型HT622型和7461型等。
这里就以这些电路的编码格式来仿真怎样使用单片机的捕获中断功能来实现其解码。 红外线通讯的发送部
分主要是把待发送的数据转换成一定格式的脉冲,然后驱动红外发光管向外发送数据。接收部分则是完成红外
线的接收、放大、解调,还原成同步发射格式相同(但高、低电位刚好相反的脉冲信号
