OK, most of that makes sense. I might have more questions latter, but one question for now. You say to use the scale_shared for the gain (can you point do a good example of this?) I just want to make sure we're on the same page as to what the gain is doing. It's really just setting the range of the voltage input I scale the result back down to volts. So if the input voltage is 0.2V you get 0.2V Whether you set the gain to 1 or 8 thanks, Paul -- 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
