But it could be a fit, maybe requires some extensions to the current IIO API though. Have you looked at the IIO API and userspace ABI to see how your device could fit in there? Also what does the data returned by the spectrometer look like? Usually the data returned by an IIO device is in some kind of standardized form, so generic applications can be written without having to know the exact data layout the device uses. I'm not an expert on how spectrometers work, what kind of parameters they have and what the result of a 'conversion' looks like. Maybe you could give a short introduction, this would certainly make it easier to figure out how this would fit into IIO. A pointer to the sourcecode of the current driver could also be useful. - Lars -- 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
