Subject: Cast the period to an integer in `demo/python/cmd.py`'s command setup.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7a277ab0cb12e7ad6b84f9973ba5c09bcbdeb1e4;p=comedilib.git

Cast the period to an integer in `demo/python/cmd.py`'s command setup.

This avoids:

  TypeError: in method 'comedi_get_cmd_generic_timed',
    argument 5 of type 'unsigned int'
