drivers read all the sensor values at once and cache the readings for a
couple seconds, so you can't get an instant reading at any time, and
they also don't support interrupts in general.
That's something of an issue when the hardware monitor
triggers alarms though, right? I couldn't figure out
how to get a TMP75 alert out to any userspace code that
would care, to pick one example, even after teaching
the i2c core how to handle SMBus alerts. ;)
I suppose this just emphasizes the point made by Hans
that we kind of need (industrial) "control" components
(or "data acquisition"?) not just "monitoring" ones.
Such alarms are of course different from the "dataWhilst this is true, most accelerometers also have "alarm" triggers, for example
ready" signals of an accelerometer.
