Subject: [PATCH v1 0/9] iio: afe: add temperature rescaling support
Date: Sat, 29 May 2021 20:59:08 -0400 [thread overview]
Message-ID: <20210530005917.20953-1-liambeguin@gmail.com> (raw)
From: Liam Beguin <lvb@xiphos.com>
Add temperature rescaling support to the IIO Analog Front End driver.
This series adds support for three kinds of temperature front end
circuits:
- temperature-sense-rtd for which the resistance is proportional to the
temperature
- temperature-sense-current for which the current is proportional to the
temperature
- temperature-sense-amplifier for which the voltage is proportional to
the temperature
At first I tried to use iio_convert_raw_to_processed() to get more
precision out of processed values but ran into issues when one of my
ADCs didn't provide a scale. I tried to address this in first patch.
When adding offset support to iio-rescale, I also noticed that
iio_read_channel_processed() assumes that the offset is always an
integer which I tried to address in the second patch.
If it makes sense to add support for fractional offsets, I could give it
a try in another series.

Thanks for your time
