Interesting... Note that, given it describes itself as a button trip I can entirely see your point with this one! I wrote my reply before opening the datasheet. oops. The device does seem to provide access to measurements related to the capacitance sensed so might be rather more flexible than just a button though. -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
