What are the differences between those > two? What are the use cases for each? Which one should I have used? First is for single channels while the latter is for differential channels. In this case it's correct to use in in_voltageX_scale_available as you did. thanks, Daniel. -- 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
