…1 原理 紅外線是不可見光，波長在770nm~1mm之間，常見於家中的遙控器。一般的紅外線傳送端與接收端需要事先規範好傳送的頻率，常見的規範有NEC, Philips RC5, RC6, RCMM, Toshiba, Sharp, JVC, Sony SIRC……。其中NEC是家電常用的規範，它使用38K Hz的頻率。紅外線接收器裡面有解調器(demodulator)，它的訊號線平常會輸出數位訊號3.3V (or 5V)。接收到一定頻率的紅外線訊號時，它的數位輸出會變成0V。如果不是這個頻率的紅外線，像是手上拿著紅外線燈開關個幾次，紅外線接收器不會對這有反應，以避免雜訊。紅外線發射器則要傳送對應頻率的訊號，一般來說是PWM訊號。一個完整的紅外線發設器的訊號如下圖，它分成幾個階段： 一開始它會送起始訊號，它分成Start high與Start low，其中Start high的訊號為PWM訊號，頻率為38K。Start low則是一般的數位輸出，只要不是PWM訊號即可，一般為了省電會將訊號置於0V。 接著會送資料，依序將資料以byte為單位送出，送的順序為LSB(Least Significant Bit) 至MSB(Most Significant Bit)。其中bit 1的表示方式，先打出長度560us的PWM訊號，再停止1.69ms。而bit 0的表示方式，打出長度560us的PWM訊號，再停止560us。可以看到0跟1的表示方式差別只在於後面的停止長度。 資料送完之後，送一個bit 1當作Stop…
