Hello everyone. I'm looking at the code and datasheet of ad2s90, trying to understand what is needed to move it to the main tree. I and my study group intend to work on it. I do not understand all the necessary steps yet, but I will present here some brief items for discussion. I'd like to ask if I'm on the right track. All feedback will be much appreciated. Some of the things that I think need to be done: - The IIO_CHAN_INFO_SCALE information mask is not set yet - The read_raw function does not return the error code returned by spi_read on failure - There is no channel for velocity yet - There are two minor codestyle corrections to be made - Maybe it's possible to change the bit operations at the read_raw for a bitops.h function call Best regards, Matheus
