Re: Checksum headaches

AS many of the bytes don't change in your signals you can save memory by hard-wiring those bytes into your code...will save lots of RAM. In addition by storing the buffers in Flash, you can store many more signals on most platforms...giving you the option for hard-wiring in all the signals you actua...

Re: Checksum headaches

@chuckindixon I checked the link out and it does not seem to work for me. We have already used techniques like this and more using AnalysIR's built-in reverse engineering tool and checksum calculator, without success.......so far! Based on the signals posted, some of the bytes/nibbles/bits changing ...

Re: Change One/Zero colors

Funnily enough, we implemented that recently when adding annotation to the trace. :)

Unfortunately, it has not been released yet.

However, If you are happy to work with it 'as-is' I can send you an exe (without install package) ....let me know

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 :mrgreen: )

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 ...
