Team,
I’ve been bashing my head against the Waveshare S3KM1110 radar device. Product page!
That product page points us to the Waveshare Wiki page for the device, but the spec for the device communication protocol there is incomplete. i.e. no description of ‘Enter Command Mode’ and the read parameter syntax talks about a parameter ID that is not described anywhere.
I have been stealing fragments from manuals of other similar chips, which are based on (but differ sometimes) the original LD2410. This is slow and error-prone.
While I cant offer a link to a full manual, one way I find to help collect data is to look at git hub projects from people the have written libraries for things.
e.g. s3km1110/src/s3km1110.cpp at main · 2Grey/s3km1110 · GitHub
If there software does everything you need, then you can reverse most of it by sniffing the serial comms.
Im more then happy to help work out the missing bits that you need (if you cant find the full guide).
Cheers and good luck.
In my humble opinion you should not have to do that. The info you need should be available without having to spend days searching.
This sort of thing is throughout this Forum concerning Waveshare products. I only purchased one pretty simple device and still have not got it to work properly. Although I admit I do drop it for long periods.
Probably the reason I only have this one product and bypass everything else from this manufacturer.
Michael, your approach of checking GitHub repos and reverse-engineering from existing libraries is definitely one of the best practical ways when official docs are lacking. Sometimes the best info is in less obvious places.
Over the weekend I had a play and some googling. Seems like the main reference everyone pointed to has gone.
This seems to be the best one I have found so far.
I d/l their software and completed a serial sniff. And so far things seem to match that reference.
there may be some bits missing or not clear, but in the most part it should be there.
Nice one, thanks for digging into it! That PDF looks like a solid lead, especially with your serial sniff lining up so far. If you spot any quirks or gaps as you go, feel free to share, might help the next person down the track
