Hi Jonathan, > I'm not really keen on doing that (as hardware gain has a well defined > different meaning). This is a rather opaque device specific value.

Oh well, another clear datasheet. :) > You are welcome, this is a fiddly device! Sane hardware would store > all these in on chip flash, but I guess it's a cost thing to not do so. I sent a patch with the updated documentation and the driver itself. Note that I left the read/write of float values as TODO (returning -EINVAL when asked for). This way I hope we can keep reviewing this driver, will trying to find the best way to deal with those annoying floating numbers. Thanks, Mathieu (I cc'd Pierre-Moana who is working with me on this driver) -- 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
