Subject: Cast the period to an integer in `demo/python/mmap.py`'s command setup.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3d79204427bfc1725d8184d6467e0a96ec4dfa89;p=comedilib.git

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

This avoids:

   Traceback (most recent call last):
     ...
     File ".../mmap.py", line 96, in prepare_cmd
       C.scan_begin_arg = 1e9/freq
     ...
   TypeError: in method 'comedi_cmd_struct_scan_begin_arg_set',
      argument 2 of type 'unsigned int'
