IIO Oscilloscope About The ADI IIO Oscilloscope is a cross platform GUI application, which demonstrates how to interface different evaluation boards from within a Linux system. The application supports plotting of the captured data in four different modes (time domain, frequency domain, constellation and crosscorrelation). The application also allows to view and modify several settings of the evaluation board's devices.

This is a tried/proven method that does everything in a quick script. To build on a host, do not use the script, you must: 1. make sure the following libraries are installed. This list is maintained in the adi_update_tools.sh shell script, and can be copied/pasted to most Debian based distributions. For others make sure they are installed, or the below steps will not work. If you are not sure how to do this consult your distribution documentation. file: adi_update_tools.sh

> aptget y install libglib2.0dev libgtk2.0dev libgtkdataboxdev libmatiodev libfftw3dev libxml2 libxml2dev bison flex libavahi commondev libavahiclientdev libcurl4openssldev libjanssondev cmake libaiodev 2. build and install the libiio library, by following these instructions. Make sure you do the final make install. 3. build and install the libad9361iio library, by following these instructions. 4. download the source > git clone https://github.com/analogdevicesinc/iiooscilloscope.git > cd iiooscilloscope > git checkout origin/master Or, download a zip, and uncompress it: rgetz@pinky:~$ wget https://github.com/analogdevicesinc/iio oscilloscope/archive/master.zip rgetz@pinky:~$ unzip master.zip rgetz@pinky:~/iiooscilloscope$ cd iiooscilloscope 5. and run `make` and `make install`. If you did not do a make install of the libiio, the libiio install location needs to be set in your path ie: (PATH=/usr/lib:$PATH“) or else an error “Package libiio not found..” will occur. rgetz@pinky:~/iiooscilloscope$ mkdir build && cd build rgetz@pinky:~/iiooscilloscope$ cmake ../ && make j $(nproc) rgetz@pinky:~/iiooscilloscope$ sudo make install 6. if you don't want to do a make install (sometimes I don't), you will need to make sure that the most recently built shared libraries can be found, by setting the LD_LIBRARY_PATH environmental variable. rgetz@pinky:~/iiooscilloscope$ export LD_LIBRARY_PATH=./ otherwise you may get an error like this: rgetz@pinky:~/iiooscilloscope$ ./osc ./osc: error while loading shared libraries: libosc.so: cannot open shared object file: No such file or directory Or, worse case, when you are debugging things, you will see your modified source code, but it will be running/executing the older shared shared object which was loaded (since it didn't find things in the library path). macOS For macOS install libiio and libad9361 from source or using pkg's on the associated release pages. If you are using the pkg's make the version used by libad9361 is the same as the release of libiio you download. libad9361 libiio

Then using brew install IIOScope: brew install HEAD tfcollins/homebrewformulae/iiooscilloscope User guide Launching the application Running Local The application can run locally which means it runs on the same platform where your device is connected. To start the IIO Oscilloscope open up the start menu of your system and search for “IIO Oscilloscope”. E.g. if you are using a Ubuntu Linux system move your mouse cursor to the left side of your screen and “Dash home” button and type “IIO Oscilloscope” into the search box. Running Remote The application can be used to connect to another platform that has a connected device in order to configure the device and read data from it. You can connect in 3 different ways: 1. Manually: This specifies any shell prompt running on the host or target Run IIO Oscilloscope in remote mode > export OSC_REMOTE=IP address of the remote platform (old) > export IIOD_REMOTE=IP address of the remote platform (new) > osc 2. Settings → Connect and enter the IP address in the popup window, and click “OK” or “Refresh”.

3. Settings → Connect and click “Refresh” with a blank IP number. If your network supports zeroconf1), you will be connected to the device on the network. Using the application Main Window Each plugin (or tab) can be detached from the main window simply by clicking on the button placed on the right side of the name of the plugin. Close the detached window to attach the plugin back to the main window. The Main Window is designed to display a configuration panel (plugin) for each device recognized by the system. Additional plugins will be loaded for device debugging and monitoring purposes such as: DMM Tab/Plugin The DMM Plugin: The Digital Multimeter continuously displays device specific data once the start button is activated. Device tab: Displays the list of all available devices. Active channels tab:Displays the list of channels that belong to the enabled devices. All

channels can be enabled simultaneously by using the All Channels button. Right side tab: Displays data readings of the enabled channels in Active channels tab. Debug Tab/Plugin Debug Plugin: Is a tool for device debugging. Since “normal” users should not be doing this, features on this tab may not work unless you have started the osc application as root (try sudo osc in a terminal). Device Selection: Sets the active device. Once a device is selected any other information displayed in the plugin is related to this particular device. IIO Device Attributes: Allows Read/Write operation for the attributes of a device. Register: Provides low level access to the registers of the device. Detailed Register Map: When enabled it displays a graphical representation of a register and groups the bits by their functionality. When disabled the newly displayed option (Register Map Type) allows the selection of the register map to be used. SPI registers refer to the internal registers of the device while the AXI Core registers belong to the HDL core associated with the device. Enable AutoRead: When enabled it allows the register to be read automatically as the register address changes. Address: The address of the register. Value: The value of the register at the given address. Hardware Specific Tab/Plugins

There may be hardware specific plugins/tabs, specific to the platform you are running on. Here are a few: Capture Window The Capture Window is where device data is displayed. Capture Window Settings Plot Title: Click Edit→Plot Title to Show Settings: Click View→Show Settings to Menu (Along top of the capture/plot window). File Edit View Save As : Saves data to file. Quit : Close the capture/plot window Plot Title : Change the name of the window.

Show Settings : show/hide all settings in the left panel and allow the plot to fill the entire window. Full Screen : Will make the window full screen. Settings Device list: Lists all available ADCs and the corresponding channels. It allows selecting the channels to be displayed. Plot type Time domain: Plots the signal in the time domain. Displays the raw samples. Sample count: Selects the number of samples for time domain, constellation and crosscorrelation plotting Graph Type: Selects the type of all graphs: lines or dots. Frequency domain: Plots the signal in the frequency domain. Performs a FFT on the signal and displays it. FFT size: Selects the size of the FFT for frequency domain plotting FFT Average: Selects the average weight to be applied to the FFT samples.

PWR Offset: Selects the offset of the FFT graph. Constellation: Plots the signal as a constellation plot. The Ichannel will be plotted on the Xaxis and the Qchannel on the Yaxis. Sample count: Selects the number of samples for time domain, constellation and crosscorrelation plotting Graph Type: Selects the type of all graphs: lines or dots. Cross Correlation: Plots the signal as a crosscorrelation plot. Sample count: Selects the number of samples for time domain, constellation and crosscorrelation plotting Graph Type: Selects the type of all graphs: lines or dots. Info Markers : Displays marker measurements. Devices : Displays Device info (sample rate) Plot Options/Icons (along top of window) Capture/stop : Starts or stops the data capture. Zoom In : Zooms in on a region of the plot.
