Use DSO Nano to read remote code

Post by abe » Tue Jun 15, 2010 4:56 am

I'd like to use the DSO nano to get the code from my remote for an arduino to reproduce its pulsating frequency can anyone tell me how to do this? I know how to program arduino in general but I have never done anything like this... In Detailed what can I do to get the code that the ir led is pulsating at for each button? meaning will the code look simle like 0x64 or will Ihave to the the arduino a code like led state = high, delay 25 led state = low delay 10, led state = high delay 100 etc....

first, you must know the protocol used by your remote.
second, the remote, don't send plain signal, but a carrier modulated, with protocol specification, the carrier may vary from 36 to 38 Khz , and the protocol may vary from RC5, to sony to toshiba.
to read the code, you must have a receiver like tsop 1738 (for 38 khz) or 1736 (for 36 khz) that receive and demodulate the signal, taking you a plain signal that you can see whit DSO.

sorry, if this may be inaccurate, but i'm starting to study the ir code now!!!
