 ====== no-OS IIO ======
+IIO interfaces and application documentation available at :
+http://analogdevicesinc.github.io/no-OS/index.html
+under IIO headline.
 ====== BUILD PROJECT WITH IIO SUPPORT ======
+To build project with no-OS IIO support go to the desired no-OS project folder ''/no-OS/projects/project_name'' and execute:
-To build project with no-OS IIO support go to the project “/no-OS/projects/project_name” and execute:
+''make reset''
-''make TINYIIOD=y''
+''make IIOD=y''
-For more information about building projects, go to: https://github.com/analogdevicesinc/no-OS/wiki/Building-no-OS-on-Linux.
+Depending on the project and hardware used, the platform might have to be specified inside the Makefile in the project folder, or from command line:
+''make PLATFORM=desired_platform clean_all''
+''make PLATFORM=desired_platform IIOD=y''
+For more information about building projects, go to: [[:resources:no-os:build|https://github.com/analogdevicesinc/no-OS/wiki/Building-no-OS-on-Linux]].
 After build, execute command:
+<hidden Xilinx(Click to expand)>
 ''make run''
+</hidden>
+<hidden Linux (Click to expand)>
+''sudo ./build/project.out''
+<note important>Make sure IIOD is not already running! It can be stopped it with: \\
+''sudo systemctl stop iiod''
+</note>
+</hidden>
 The binaries are loaded to the board. Next, it is possible to connect with a libiio client.
-===== IIO-Oscilloscope client =====
-IIO-Oscilloscope is one possible client (it has to be built with SERIAL_BACKEND option), select the corresponding serial port and set baud rate to 921600. For more information about IIO Oscilloscope go to:
+For debugging and development execute command:
+''make develop''
+===== Connecting to Clients =====
+After building and running a no-Os project, the data can be displayed, processed and visualized through a series of clients, such as command line tools, MATLAB® and Simulink®, IIO-Oscilloscope, etc. Find the complete list of frameworks and applications at http://analogdevicesinc.github.io/libiio/master/index.html
+For simply displaying or storing information regarding the devices, [[:resources:tools-software:linux-software:libiio:iio_info | iio_info]], [[:resources:tools-software:linux-software:libiio:iio_attr | iio_attr]], [[:resources:tools-software:linux-software:libiio:iio_reg | iio_reg]], [[:resources:tools-software:linux-software:libiio:iio_readdev | iio_readdev]], [[:resources:tools-software:linux-software:libiio:iio_writedev | iio_writedev]] are included in the default builds.
+Here is an example on how to use ''iio_info'' :
+  * For serial context ''iio_info -u serial:/dev/ttyUSB0,115200''
+  * For network ''iio_info -u ip:<host>''
+For a graphical user interface and plots IIO-Oscilloscope is one possible client. For more information about IIO Oscilloscope go to:

-===== Helper utilities as client =====
-Helper utilities from Libiio can be used also:
+And with network:
-''iio_readdev -u serial:/dev/ttyUSB0,921600 -b 400 -s 6400 cf-ad9361-lpc > sample.dat''
+{{:resources:tools-software:no-os-software:screenshot_from_2021-04-29_02-04-15.png?400|}}
+Once connected, two windows should pop up.

+{{:resources:tools-software:no-os-software:screenshot_from_2021-04-29_02-06-48.png?400|}}
+===== Python device over iio client =====
+A python abstraction module for ADI hardware also exists, to make them easier to use. The supported devices can be found at
+https://analogdevicesinc.github.io/pyadi-iio/devices/index.html
-For more details about libiio helper utilities please visit following link:

 ====== IIO DEMO APPLICATION ======
 A demo iio application can be found in the following location:
-https://github.com/analogdevicesinc/no-OS/tree/iio_demo/projects/iio_demo
+https://github.com/analogdevicesinc/no-OS/tree/master/projects/iio_demo
 This project is independent of a physical device and should be used as reference, when creating a new iio application for a new iio device.
+To view information regarding the devices, one can use:
+''iio_info -u serial:/dev/ttyUSB0,115200'' \\
+or, \\
+''iio_info -u ip:host'' (only on Linux)
 To load data into RAM, that could be seen in iio-oscilloscope application, execute the following command:
-''cat sample_sine.dat | iio_writedev -u serial:/dev/ttyUSB0,921600 -b 400 demo_device''
+''cat sample_sine.dat | iio_writedev -u serial:/dev/ttyUSB0,115200 -b 400 dac_demo''
-This will write 400 samples to “demo_device” from “sample_sine.dat” file.
+This will write 400 samples to “dac_demo” from “sample_sine.dat” file.

 ** iio_app** – IIO application interface. Sets IIO application communication interface and executes the main application, where commands are received, parsed, and executed. This module is necessary.
@@ Line 48: / Line 96: @@
 ** iio_axi_dac** – This module will register a new interface into iio_interfaces element. It also creates an iio_axi_dac device instance and a struct iio_device element, that specifies it’s channels and attributes. Wrapper over axi_adc_core, it adapts the interface to iio. This module is optional.
-** iio_demo** – This module is hardware independent and should be used as reference, when creating a new new iio device.
-** iio** – Sets tinyiiod ops callbacks for communicating with the client and ops callbacks for communicating with IIO devices and contains the callbacks used by libtinyiiod.
 ====== SOFTWARE ARCHITECTURE ======
-The relations between modules can be seen in the following figure. Doted lines represent function callbacks.
+The relations between modules can be seen in the following figure.
-{{:resources:tools-software:no-os-software:iio:iio_arhitecture.png?direct&800|}}
-An iio_app instance is always necessary, since it instantiates libtinyiiod library, the rest of iio modules (iio_demo) are optional, each one registering a new device to be checked when a command is received.
-====== LIBTINYIIOD ======
-Is a library to ease the development of software interfacing I/O (IIO) devices. The library abstracts the low-level details of hardware, and provides a simple yet complete programming interface that can be used for advanced projects.
