This rangefinder uses an spi device to send pulses and an iio driver
in buffer mode to get data
The data is then analyzed and the maximum pulse received is considered to
represent the echo of the pulses that have been sent. The distance in time
between the pulse that is sent and the pulse with the maximum amplitude
is used to calculate the altitude based on the speed of sound.
There is a dependency with libiio, and in order to build, there is a need
to provide a rootfs that includes libiio.a.
The other solution is to build dynamically after having updated the rootfs
to use on compiled with a more recent toolchain and include libiio
