Hello,

Looks like this board and the chip is potentially pretty niche and so writing a component around it at the moment probably isn't that appealing. I say this mainly because I can't find them for sale anywhere.

However the I2C interface looks simple enough so I've put together an example for you that should work.

If this board or chip becomes a bit more mainstream then yes certainly worth writing a component for it.

Please note I haven't looked at the library you suggested and so my demonstration threshold values etc may be incorrect.

Based on the datasheet I found here.

Thank you very much, I'll give it a try.
