Run the ADRV9002 Demonstration Standalone - ArrowElectronics/data-storm-daq GitHub Wiki

The DataStorm DAQ development kit can be run as a standalone desktop computer. This hardware configuration requires a keyboard, mouse, and HDMI monitor

Configuration for local IIO Oscilloscope access

The ADRV9002 Evaluation Platform in this configuration is comprised of the following components:

Assemble the Hardware

Follow the steps in the order shown below.

  1. Insert the EVAL-ADRV9002NP/W1/PCBZ FMC connector into the FMC mating connector on the Trenz TEI0022 board
  2. Attach the monitor to the TEI0022 using an HDMI cable
  3. Attach the keyboard and mouse to the TEI0022 using any of the 4 USB ports
  4. Connect the RG316 RF Cables between RX2A_IN and TX2_OUT SMA connectors
  5. Connect the RG316 RF Cables between RX1A_IN and TX1_OUT SMA connectors
  1. Connect the power supply to the TEI0022
  2. Plug the AC-DC adapter into an AC outlet

Configure BOOTSEL DIP Switches

Select the SD card as the boot source for the processor. Modify the DIP switch settings to match the image below.

Configure FMC_VADJ DIP Switches

The FMC_VADJ power rails provide power to the EVAL-ADRV9002NP/W1/PCBZ via the FMC interface. This is an adjustable voltage. It must be set to 1.8V. Failure to do so can potentially cause damage to the EVAL-ADRV9002NP/W1/PCBZ. Modify the VID_SW DIP switch settings to select 1.8V.

Modify the DIP switch settings to match the image below.

Run the demonstration standalone

Power up the unit and wait approximately 60 seconds for the unit to be fully functional.

  • Select DAC Channels voltage0 and voltage1

View the wave in the frequency domain:

  • In the Plot Type section select the Frequency Domain mode.
  • Select a 4096 FFT Size and set Average to 10.
  • Press the Capture / Stop button for a continuous display of the spectrum.

Change the file selection to LTE20

Change the file selection to Tx_20MHz_245.76Msps_PeakScaling3.0dBFS_ETM1.1_PAR7.5db_Offset0MHz_4Carrier

Run the Example Applications

The LibIIO library API enables access to the transceiver data from C code, Python code, or MATLAB. A small sample of C and Python codes are provided for the reader and can be run natively on the DataStorm DAQ.

NOTE: All examples shown below are demonstrated with an internal loopback configuration enabled on both TX channels in ADRV9002.

Review the Python source code

  • Open a Terminal. Click on the Terminal icon on the top bar of Desktop

      $ cd examples/python-examples

  • Review the Python source code

      - Open the file explorer from the top bar and navigate to examples/python-examples
  - Double click on the file adrv9002_example.py to review in the text editor

NOTE: Python script, by default, runs on a DDS mode configuration. To use any other TX modes available in the FPGA, use the variable TX_DAC_MODE as shown below and set the value according the instructions provided in the code comment.

  • Run the Python source code on the Terminal

      $ python3 adrv9002_example.py

This capture shows a DDS single tone waveform with its I and Q components at a -10kHz frequency and a 0.9 scale value.

Review the C source code

  • Open a Terminal. Click on the Terminal icon on the top bar of Desktop

      $ cd examples/c-examples

  • Review the C source code

      - Open the file explorer from the top bar and navigate to examples/c-examples
  - Double click on the file adrv9002-iiostream.c to review in the text editor

NOTE: C program, by default, runs on a DDS mode configuration. To use any other TX modes available in the FPGA, use the variable TX_DAC_MODE as shown below and set the value according the instructions provided in the code comment.

  • Compile the C source code on the Terminal (Use -liio flag to dynamically link the LibIIO libraries)

      $ gcc adrv9002-iiostream.c -o adrv9002-iiostream -liio

  • Run the C executable using sudo permissions. Password is analog.

      $ sudo ./adrv9002-iiostream

Shutting down the demo

  • Power down the target. Launch a Root Terminal. Type the following

      $ poweroff

  • Wait 30 seconds and then you can safely power down the DataStorm DAQ
