No too early to worry about that yet.
- INT synchronous with new samples isn't working
Didn't finish meddling with it yet, we didn't ask ST for support yet
either. If it can't work but everything else does, we can still come
and poll it ourselves asynchronously and get what should be reasonable
if not ideal behaviour. I have a trick in my back pocket that will
enable us to do that nicely if we have to.
- There is a danger communication can get corrupted between the two
This seems to be real but it can only happen under very specific
circumstances that we probably never generate, also strobing the
disabled device CS inbetween clocks might ensure the disabled device
never sees enough I2C clocks to do anything.
So we need to meddle on... after tea :-)
