Open source Gendex GXS700 / Dexis Platinum USB x-ray sensor driver

Installation (python3)

Instructions for Ubuntu 16.04

sudo apt-get install -y git python3-pip python3-numpy fxload
sudo pip3 install libusb1 scipy
# Optional for WPS7 x-ray head support
# Not needed by the vast majority of users
sudo pip3 install pycurl
git clone https://github.com/JohnDMcMaster/gxs700.git
cd gxs700
sudo ./udev.sh
sudo python3 setup.py install

Now plug in your sensor

TODO: add info about optional fxload. TLDR wanted Windows support so didn't fully move to it

Installation (python2)

Alternatively if you have python2 you might get away with running an old release:

sudo pip install gxs700

I'll cut a new pip release after the py3 code stabalizes

Test

See if basic communications can be established:

gxs700-dump-dev

Now take a dark frame:

gxs700-main --force-trig

You should get files in directory "out". Sample output:

$ gxs700-main --force-trig

If you have a working x-ray source, run the following and then light it up with x-rays:

gxs700-main

Assuming your x-ray source is intense enough, it should trigger a capture.
