SI1133 light sensor: Is there anything to refer to?

SI1133 light sensor: Is there anything to refer to?

[Olivier Dugas]

Hi,

We've recently been trying to make the SI1133 light sensor work 
according to what's written in its datasheet. Unfortunately many 
questions remain and the si1145.c driver seems largely different from 
si1133. We believe that any code sample would be of a great help. Are 
you aware of any driver, unmerged patch or other code sample for this 
sensor?

Regards,

the si1133 belongs in the same family as the si1153 which has a different 
register layout than the previous chips, so I think a separate driver is 
needed

I do have an eval board for the si1153 and started a driver, but it's not 
ready for submission (yet), the si1133 should be a lot simpler than the 
si1153

regards, p.

Excellent news. I'll keep a watch for this new driver to show up.
In the meantime, we just got the sensor to respond correctly using 
i2cget|set commands.

FYI, the issue we had was that the reset value of ADCCONFIGx is not 0x00 
(as specified by the datasheet), but 0x0f, which selected no photodiode. 
Hence, we received only noise values.

Thanks a lot and have a good day

Hello Peter,

Do you have any progress that could be shared for si1153?

Even if it's not complete I could use it to begin si1133.

Thanks,
Maxime.
