% CMCheckInit([meterType], [PortString])
%
% Initialize the color meter. The routine calls the
% lower level routines for given 'meterType'. If the low level routine
% fails, this routine retries, then prompts the user to take appropriate
% action. If the low level routine succeeds, this
% routine is silent.
%
% The following colormeters are supported:
%
% meterType 1 is the PR650 (default)
% meterType 2 is the CVI (need CVIToolbox) - Not yet implemented!
% meterType 3 is the CRS Colorimeter
% meterType 4 is the PR655
% meterType 5 is the PR670
% meterType 6 is the PR705
%
% For the PR-series colorimeters, 'PortString' is the optional name of a
% device string for the serial port or Serial-over-USB port to which the
% device is connected. If none is given, the routine uses different files
% and built-in defaults to try to find the proper port: If there is a file
% 'CMPreferredPort.txt' in the search path of Matlab/Octave, it will parse
% that file for a PortString to use. Else it will use a hard-coded default
% inside this routine.
%
% If a calibration file with name 'PRXXXPorts' for the PR-XXX exists,
% it will override what is in CMPrefferedPort.txt. There are two
% possible formats for the structure in this file.
% If the structure has a PortString field, this is passed to
% routine FindSerialPort to get the actual port. Otherwise,
% if the structure has a .in field, this string is used directly.
%
% Other Colorimeters, e.g., CRS ColorCal, have their own specific setup
% methods and this routine just calls their setup code with default
% settings.
%
% 9/15/93 dhb Modified to use new CMInit properly.
% 1/18/94 jms Added gHardware switch
% 1/24/94 dhb Changed sign of gHardware switch.
% 2/20/94 dhb Call through CMETER rather than CM... routines.
% 4/4/00 dhb Optional port name, only used on SERIAL version.
% 9/11/00 dhb Added meterType.
% 1/4/02 dhb, ly Try to get OS9 version to work with Megawolf board and SERIAL.
% 1/10/02 dhb, ly Change calling convention. Remove passing of port, but read
% port from a "calibration" file in PsychCalLocalData if it's there.
% 4/13/02 dgp Cosmetic.
% 2/26/03 dhb Add CRS Colorimeter, change meter type of PR-650 to 1.
% 10/05/06 dhb, cgb OSX version.
% 11/27/07 mpr replaced hard coded portNameIn with FindSerialPort for OS X, and
% attempted to make this more robust and user-friendly.
% modifications tested only on Mac OS 10.5.1, Matlab 2007b, on
% a Mac Pro. Other systems may require more tinkering...
% 2/07/09 mk, tbc Add PR-655 support.
% 2/07/09 mk Add experimental setup code for use of IOPort instead of SerialComm.
% 2/11/09 cgb,mk Small fixes: Now we use IOPort instead of SerialComm --
% by default. Verified to work for both PR650 and PR655 toolboxes.
% 7/16/12 dhb Choose right global default for 64-bit Matlab. Hope I
% did this in a way that doesn't break anything else.
% 7/20/12 dhb Undid 7/16/12 change. Error was due to a stale IOPort on my path
% 12/04/12 zlb Adding PR-705 support.
% 4/10/13 dhb More flexible behavior supported via PRXXXPorts calibration file.

% I wrote the function FindSerialPort before I discovered CMCheckInit had
% been ported to OS X. It may generally require less of users than relying
% on what amounts to a preference in the calibration files. The default
% for portNameIn was 2, but on my machine it was 1 when I wrote my
% function. Someone in the Brainard lab may want to generalize
% "FindSerialPort" to work with OSs other than Mac OS X and then use that
% function in lieu of meterports=LoadCalFile. I am not intrepid enough to
% take that step. -- MPR 11/21/07
