Am I the only one who thinks the whole concept is a pretty weird idea ? IIRC the machine becomes slower when it *thinks* its on my lap, but runs faster - and becomes hotter - when it's laying around somewhere, eg. ontop of some papers ? Where can I get the drugs that these guys took ? :o > With upcoming WLAN cards with configurable transmit power, > this will also be used as what you call a SAR device. Same fun. Once a person comes near, the signal gets weaker and potentially connection breaks. Great fun for debugging. Back to the technical side: IMHO we should first work out what the actual purpose of these sensors could be - are they useful for anything else than just these specific cases ? If not, I'm not sure whether it makes sense to put them into IIO at all, but using a specific board driver instead. Okay, maybe we find these sensors somewhere else (maybe some embedded stuff), for completely different purpose - in that case having one standard driver (for the sensor itself) could make sense. But that leads me to bigger topic: we've got several cases of some sensors/chips used in different subsystems, eg. simple one-shot ADCs, eeprom's, etc. ... maybe we should move them to separate subsystems, which then can be wired to other (more specific) ones in a very generic way ? ... just some quick+dirty thoughs, --mtx -- --- Hinweis: unverschlüsselte E-Mails können leicht abgehört und manipuliert werden !
