Hi,

What do you mean by "Toggle bit" ????? Please explain that in detail for our understanding.

What do you mean by "toggle the desired I/O bit of MCU at any port". ?????? Please elaborate this too.


Now, can you kindly let us know, how much experience do you have in MCU programing and making prjects with it ???

For your information regarding decoding of RC5 or "ANY IR REMOTE CONTROL":

Every key on the remote transmits a separate code. The initial length of the code Off all the keys is same which is the footprint or the address or the ID of that particular remote control model so that only this remote would work on a particular machine (for example a tV or a dvd player etc.)

Rest of the code is unique with everykey using what at the receiving end every key on the remote is assigned a specific function.

Having said that, when you say you have decoded the RC5 then it means you are getting, a Unique code in your MCU RAM thru your "TSOP17 IR receiver 3 pin module". Is this right ????

If right, then assigning any key on the remote to perform any function on the MCU would be a child's game, if you have any experience handling MCUs........

In all such generic IR remote projects the most difficult part is the remote decoding. I do not know how you managed to decode the IR, but what I do is entirely a different and wierd technique that using it you can practically and uniquely decode "any" remote IR or RF in the world. And with my technique you don't even need to know what is the protocol type for example RC5 or SONY or what ........ You only need to capture the whole stream and follow the pattern that you get from each key.

Use the address / footprint part of the IR stream for the Uniqueness for that particular handheld IR remote unit and use the rest of the stream for key identification.

I hope you get the hint really well :-)
