Subject: Problem about Read Multiple Raw Function
Date: Tue, 26 Nov 2019 12:56:11 +0000	[thread overview]
Message-ID: <OSBPR01MB2326981343F90B11AB6CA23DB1450@OSBPR01MB2326.jpnprd01.prod.outlook.com> (raw)

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
