Summary
Linux® kernel provides some user space tools that can be used for testing the IIO subsystem.
Contents
1 Article purpose[edit]
The purpose of this article is to:
- briefly introduce the IIO user space tools that comes with the Linux® kernel
- provide a few examples using these tools
2 Introduction[edit]
These tools use IIO sysfs and character device directly without libiio (See IIO user space interface for further details).
3 Tools[edit]
The Linux® kernel provides the following IIO user space tools:
- lsiio: example application that provides a list of IIO devices and triggers.
root@stm32mp1:~# lsiio Device 001: 48003000.adc:adc@100 Device 000: 48003000.adc:adc@0 Trigger 018: tim3_ch4 Trigger 007: tim1_ch3 ...
-
iio_event_monitor: example application that reads events from an IIO device and prints them.
See How to get ADC analog watchdog events.
root@stm32mp1:~# iio_event_monitor /dev/iio:device0 & Event: time: 1529352199639112110, type: voltage, channel: 0, evtype: thresh, direction: either Event: time: ...
- iio_generic_buffer: example application that reads data from buffer.
- iio_utils: set of routines built-in above IIO tools, typically used to access sysfs files.
4 Source code[edit]
The Linux® kernel IIO tools source code can be found under tools/iio[1] directory:
- tools/iio/lsiio.c
- tools/iio/iio_event_monitor.c
- tools/iio/iio_generic_buffer.c
- tools/iio/iio_utils.c
5 Installation on your target[edit]
The Linux® kernel IIO tools aren't embedded by default in OpenSTLinux distribution. They can be compiled independently and then installed on the target. See How to build Linux kernel user space tools.
