To prepare the SD-card for the DE10-Nano board:
Once microSD card has been imaged, safely remove the hardware from the SD card writer, and insert the card directly into the microSD card slot on the DE10-Nano.
Down the latest IIO-Oscilloscope release from Github, and install it on your PC. (You may need to right-click the installer, and run as “Elevated” in order to get it to install. )
The DE10-Nano comes ready to use out of the box, but it is important to double check that the FPGA Configuration Mode Switch (S10) is configured properly. See the image below for the proper configuration, and if more information is needed, check out the getting started guide.
Connect the power, cables, and sensor according to the diagram below.
Once the microSD card and cables have been connected to the DE10-Nano and CN0540 its now time to boot the system.
If you don't have a network available and want to stream data directly from the Ethernet port of the DE10-Nano to the Ethernet port of your PC that is still possible, but requires some extra configuration. Please see the Network Configuration page for complete details.
Before you can start gathering data, you first must locate the CN0540 on your network.
Now its time to start communicating with the CN0540 so you can start streaming data. When you first open IIO-Oscilloscope you'll see two windows.
The CN0540 IIO Plugin automatically configures the CN0540, so it is ready to use as soon as you run the application. Calibration of the sensor is also automatically performed so that a user can start using the capture window to collect and analyze data. No other configuration is required for the application.
If you want to re-calibrate the system, shut the system down, or modify individual registers of the devices on the CN0540 that can also be done either using the CN0540 Plugin or using the DEBUG panel to write/read specific registers. This is optional and typically application specific.
Below is a picture of what the CN0540 IIO Plugin looks like.
