Hey Pals,
My aim is to control TV (RC5 compatible) using microcontroller 89C61X2....
I tried...
1. Generating Code using Controller and carrier of 36 KHz using IC 555. I could generate the theoretical waveform but TV is not responding.
2. when I saw remote Control waveforms on DSO.. i couldnt see the carrier.. why ? how could it be possible.
3. I studied the IC PCA8521.. but couldnt really understand.. how command and device selection is done..
Is there any other way I can do it.... any IC or ckt.... PLZ help me GUYS....
