[PATCH v2 0/2] iio: chemical: Add support for sgp40 gas sensor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch set adds support for sensirion sgp40 gas sensor.

Many thanks for the in-depth reviews, especially of Jonathan who triggered
some important improvements for v2:
- provide more precision for voc value; this in turn triggered the folling
  point:
- rework of e^x calculation with an optimization on the interesting range
  between e^(-6) and e^6
- restructure use of endian types
- use __packed structures for sent telegrams
- optimize usage of mutex
- optimize switch-cases
- replace attributes by read_raw() and write_raw() values
- add documentation in Documentation/ABI/testing/sysfs-bus-iio-sgp40 as
  well as in the source code
