#98313 - IR BURST (38kHz), Only for 100 mS ? |
Hi,
I need to hold ir receiver output to be Low, as los as the carrier fequency of 38kHz still on air. But, the out put only Low for 100 ms, and start to High again even if the carrier frequency still on. The f carrier must be stopped first for some while, then run again to trigger the ir receiver to output a Low. Some one please, if there any idea how to force ir receiver's output always Low while the carrier f still transmitting. Thank you in advance. Kurnia Brahmana |
