Re: Help decoding unique protocol of a toy robot
looks like you have it sorted OK Additional comments: - to be on the safe side you can use +/-200uSecs on any value to determine if it matches a particular value. This accounts for the specs of IR receivers (up to +/-200uSecs on a mark or space) - Without having the original specs it is not possible...

Re: Help decoding unique protocol of a toy robot
Yes If its less than 1000 long its a zero...otherwise a 1 So the value is correct for the shorter pulse and you just need to note that there is an extra 1 when it is longer So for example The signal OD_Disable decodes to 3F00, but it is actually 7F00, when the extra 1 bit is added Also to decode sub...

Re: Help decoding unique protocol of a toy robot
Some progress made after figuring out that this is a very unusual protocol.... It seems the header is just the mark and each bit starts with a space followed by a constant width Mark. Thus it is a 16 bit protocol. I have managed to configure this using our generic decoding algorithm. However it will...

Re: Help decoding unique protocol of a toy robot
Yes, I saw that...thanks for the order.
Sorry about the delay in getting back to you, we had a big/extended National Holiday here late last week/end (St Patrick's Day )
I should be able to get back to it over the next couple of days.

Re: Checksum headaches
Unfortunately, have not been successful on this one for many years of trying. Part of the reason is that it is 67 bits and not a multiple of 8 or 4 bits. However, my best guess is - using LSB8 - sum of nibbles excluding last nibble - There seems to be some consistency with the 3rd bit of the nibble ...

Re: Help decoding unique protocol of a toy robot
First of all thanks for the detailed post. It should be straight forward to add support for this protocol. However, some Questions: - what is the make and model# of the remote and robot - Each captured signal seems to have a lost of bursts of data (some repeated). So to zoom in on whether each comma...

Re: Wrong IR Codes Received
How does that work? IR receivers distort the signal timing (because of the way they work). So what starts out as an even duration pulse can be distorted. A good site to get an understanding of IR remote control ( search: sbprojects ir and go thru the menu of topics) How were you able to simplify th...

Re: Wrong IR Codes Received
You should still have a series resistor in your circuit to limit current. (unless you have characterized your emitter circuit - including failure modes as well) Pick a TSOPxxx38 (last 2 digits are the carrier frequency) pick the ones with 5 numbers as they are usually more modern versions. For the W...

Re: Wrong IR Codes Received
Some initial comments...based on a very quick read I presume you are not trying to send & receive simultaneously on the same module. => Turn off the receiver while you are sending and for a little while after that.....~150mSecs approx Put a resistor in line with the IR LED, Start with 10R and yo...
