A julia package to communicate with the MCA8000D device. The package wraps the python code written by Henning Fo (https://github.com/HenningFo/mca8000d). The code was modifed to be compatible with python3. Specifically python3 enforces encoding of str/bytearray conversions, which was fixed in a few places.

pkg> add https://github.com/mdpetters/AmptekMCA8000D.jl.gitTo allow any user access to the mca8000d device, copy the file mca8000d.rules to /etc/udev/rules.d
You have to reload the rules after you copied the file to have any effect. You also could restart the computer, after reboot the rules will take effect too.
You need to install the python-usb library (pip install pyusb) with the python distribution invoked by PyCall.jl
