IIO Linux kernel tools
Linux® kernel provides some user space tools that can be used for testing the IIO subsystem.
1 Article purpose
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
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.
- 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
The Linux® kernel IIO tools source code can be found under tools/iio directory:
5 Installation on your target
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.
