Hi Rohit, There are many companies for hobbyists which sell sensors included in IIO subsystem and for sure some electronic component store in your local area. Price of sensor can be from 0.10 USD to 10 USD. Then you plug this sensor to your Linux board (Beaglebone Black is Linux Foundation preferred, although there are others including Raspberry PI - can even be RPI Zero if you are on a budget, Odroid, Linaro, ...) and you will need to provide correct voltage/current for the sensor. Easiests is that you pick sensors which are 3.3V or 5V domains, because you have pins on most Linux boards with this voltages and these pins supply enough current for most iio sensors. Then you just connect (wire) power pin on sensor to power pin on your board, and then communication pins from sensor to board and ground from sensor to board. Some addition into dts will be needed for the Linux to know where your sensor is connected at, but then it should work as plug-and-play. I hope I did not miss too many steps in between :) Crt On Wed, 25 Sep 2019 at 10:18, Rohit Sarkar <rohitsarkar5398@xxxxxxxxx> wrote: > > Hi, > This is probably a real rookie question. > I have been interested in contributing to the driver subsystems such as > iio.
