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 "data ready" signals of an accelerometer. - Dave
