Hi, I am developing Linux iio driver for one sensor and sensor provides 15 measurement samples that have to been sent the user-space for high level algorithm. I can read data from dev/iio:device and I can apply high-level algorithm. However, I have problem about read_raw_multi function. Max_len pass value as INDIO_MAX_RAW_ELEMENTS in iio_read_channel_info function that locates in industrialio-core.c file and INDIO_MAX_RAW_ELEMENTS is defined 4 in iio.h file. Is there any specific reason to define 4 ? Because in that way I cannot pass 15 values to user space with read_raw_multi function. Thanks, Özgün Kemal Günyeli
