#137230 - Emitter generates 38Khz Responding to: ???'s previous message |
Bruce,
I generate 38Khz with 8052 and I checked it in the Keil scope for generation of 38Khz. Also I tried generating 38kHz with IC555. I connected the output of 1738 to drive a LED and I could see whenever I point the transmitter to 1738 the LED glows. Now my questions are, 1) I just want to get logic '0' at output of 1738 for 2us, to generate INT0 . What is the waveform which need to be send from IR txer? Becasue in datasheet of 1738 I see a continous 38kHz from IR tx will be rejected by 1738. 2) Will you suggest any working circuit of 1738 interfaced to 8051? Thanks an regards, Danaraja |
