I'd start from finding sensor's datasheet

Its hard to find anything from smartsense
. They label their product flyers
as datasheet
. Even in Chinese Forums.
And the vendors say they do not have them.
Hard does not mean impossible. I have a few here https://github.com/themactep/openipc-wiki/tree/master/hardware/components/sensor/docs/ but not for these particular models.

Wow, thank you. Very interesting. How + where did you get them?
I know a guy who knows a guy, you know... LOL. Google and other search engines can do magic.
They are marked as Company Confidential
and SmartSens Confidential - NDA only
.
No chance for me with google & co.
Problem
There are 3 sensors in the openipc repos that have the same chip ID
cb3e
and are all seen assc223a
by ipctool.ipctool handling chip id
cb3e
History
Here we found out that there may be different "versions" of the sc223a.
Thanks to @johndi3 who mentioned
sc233a
and thanks to @themactep who helped discovering the ChipID.Solution
As done here we should regard more registers to differentiate between the 3 sensors.
ToDo
If you have one of the 3 sensors, please post the result of this command:
That will show your device ID + some more registers.
The output of my "version" of the sc223a (sold as sc5239s) is:
The important part here is
CB 3E 01
. The register0x3109
(here value01
) can differ between the 3 sensors.We need to find the different values of register
0x3109
for each of the 3 sensors. Thank you.
