evalcontrol

A python library to control the AD9959 DDS Evaluation Board. This library is based on the MIT Labview drivers and the official documentation of the AD9959.

Installation

To install the package from source simply do

git clone https://github.com/Schlabonski/evalcontrol`
cd evalcontrol
python3 setup.py install

Requirements: This library works on top of pyusb which uses libusb so these should both be installed as well. To install liusb on windows, see instructions below.

Use without sudo

If you want to use the library, i.e. access the evaluation board, without root rights run the following steps first.

  1. Add the user to the plugdev group sudo useradd -G plugdev USERNAME
  2. Add the evaluation board to the plugdev group by edditing a new rules file sudo vim /etc/udev/rules.d/10-ad9959.rules and adding the following line ATTRS{idProduct}=="PRODUCT_ID", ATTRS{idVendor}=="VENDOR_ID", MODE="666", GROUP="plugdev" where PRODUCT_ID and VENDOR_ID are replaced by the respective IDs (mind the quotes).
  3. Reload the udev rules sudo udevadm trigger

Use with artiq

To use the package within artiq just activate the corresponding virtual environment and run python3 setup.py install When accessing the device in the preparation phase of an experiment, use the AD9959.reset() method to prevent USBErrors due to timeout.

Use on Windows

To use this package on windows, you need to install a port of the libusb driver.

  1. Download from https://sourceforge.net/projects/libusb-win32/
  2. copy libusb0.dll to C:\Windows\System32
  3. copy libusb0.sys to C:\Windows\System32\drivers
  4. add a filter for the AD9959 using the install-filter-win utility
