support for GeRM

This includes

• ØMQ server to run on the zinc board to expose the FPGA registers and publish the measured data :file:`src/germ_zserver1.c`
• ØMQ consumer in python :file:`pygerm/zmq.py`
• a python IOC for exposing the GeRM to epics (:file:`pygerm/caproto.py` and :file:`cli/germ_ioc.py`). This IOC writes the measured data to hdf5 files and inserts documents in to a FileStore instance.
• Classes for exposing the IOC to ophyd/bluesky (:file:`pygerm/ophyd.py`)
• Handler for reading the files written by the IOC back through DataBroker (:file:`pygerm/handler.py`)
• A simulated detector for testing (:file:`cli/det_sim.py`)
• An example configuration file (:file:`config/97-germ.py`)
• Qt GUI to test triggering the detector (:file:`MARS_DAQ_qt.py`)
• Qt GUI for ASIC configuration (:file:`AJK_parametertree.py`)

Testing

To test this locally (with out access to a real detector), first start the detector simulation

python cli/det_sim.py

Then the IOC

python cli/germ_ioc.py localhost

If starting the IOC against the real device use

python cli/germ_ioc.py 10.60.0.160

To test the python side, first fire up IPython

ipython

and then run the example configuration:

%run -i config/97-germ.py

You should then have RE (the RunEngine), db (a DataBroker instance), and germ (the GeRM device) in your local namespace.

To run a simple count

RE(bp.count([germ]))

and get the header for than run back:

h = db[-1]

To plot a energy bin by channel heat-map:

img = make_mars_heatmap(h, np.linspace(0, 4000, 4000))
fig, ax = plt.subplots()
ax.imshow(img, aspect='auto')

or a counts per channel histogram:

channel_counts = make_mars_line(h):
fig, ax = plt.subplots()
plt.plot(channel_counts)

Running

source activate germ_ioc
python cli/germ_ioc_udp.py 10.28.0.48 10.28.0.210

may need to resart if handshaking with collector gets out of sync
