Handel¶

A python binding for the handel library.

System requirements¶

The handel DLL files need to be available in PATH (/usr/local/bin in Cygwin for instance).

Python compatibility:

python 3.7

Usage¶

Example usage:

>>> from bliss.controllers.mca.handel.interface import *
>>> init('xmap.ini')
>>> start_system()
>>> get_detectors()
['detector1']
>>> get_modules()
['module1']
>>> get_module_type('module1')
'mercury'
>>> get_channels()
(0,)
>>> start_run(0)
>>> stop_run(0)
>>> get_run_data(0)
array([13260, 52275,   256, ...,     0,     0,     0], dtype=uint32)

Gevent mode¶

Make the interface gevent-compatible using:

>>> from handel.gevent import patch
>>> patch()

Scripts¶

A few scripts are provided:

parse_error_header.py which parses handel_errors.h and output a python dictionnary of handel errors

Entry points¶

bliss-handel-server which serves the handel interface over the network using bliss rpc.
