Writing user-space IIO applications
After the long journey through the kernel-side implementation, it might be interesting to have a look at the other side, the user space. IIO support in user space can be handled through sysfs or using libiio, a library that has been specially developed for this purpose and follows the kernel-side evolutions. This library abstracts the hardware's low-level details and provides an easy and comprehensive programming interface that can also be used for complex projects.
In this section, we will be using version 0.21 of the library, whose documentation can be found here: https://analogdevicesinc.github.io/libiio/v0.21/libiio/index.html.
libiio can run on the following:
- A target, that is, the embedded system running Linux that includes IIO drivers for devices that are physically connected to the system, such as ADCs and DACs.
- A remote computer connected to the embedded system through a network, USB, or serial connection. This remote...
