That would be me ;) Back at the dawn of time for IIO - this was one of our original drivers (the sca3000 was to and that's still in staging too - that one is a seriously odd beast). Technically I still have a board with one lis3l02dq on it somewhere around, but I haven't booted it in a few years and it has darned silly connectors so wiring it up to something else would be 'interesting'. Not to mention, if I recall correctly this chip only gives level interrupts and the board only has edge triggered ones. Were some nasty games to discover if new data had turned up whilst you were reading the old stuff. I'm almost tempted to drop the driver entirely on the basis the only boards I know ever had one have been unavailable for a long time and I'm the maintainer of those anyway and given complete lack of patches for the last 5 years may have the only ones that even work (probably) any more... I can always bring it back up if I ever actually make the board boot again. p.s. Now it will turn out there are hundreds of people using intel research stargate 2 imb400 sensor boards.... (they were also compatible and sold by CrossBow for their imote 2 boards but those went all .net for no apparent reason. It was interesting hardware. The camera board for instance had no pull ups on the i2c bus so the tinyos driver that was the only documentation effectively simply never read back or checked for acks from the sensor. Gives you an idea of the fun. Still these were very small boards that well predated the gumstix etc. Ah, the glory days when I regularly fired up actual hardware!
