Thanks a lot for your review.
Any way to get the result with offset value in the iio-consumer side?
What I need is as below.
result = raw * scale + offset
At this moment, there are two apis() for reading the iio channel
- iio_read_channel_raw() and iio_read_channel_scale().
Does it sound good if I add iio_read_channel_offset() consumer api
using IIO_CHAN_INFO_OFFSET?
Best Regards,
Milo
