Description:
------------
      Giotto package is tool for acquisition images from Giotto parallel CMOS sensor       directly from Matlab.

Compiling note:
---------------
     First you must set default C++ compiler as Microsoft Visual C++ compiler. Go to ~matlab/bin directory and write mex -setup. Choose specific compiler. 
     Then you must change file mexopts.bat from your profile directory. This file is different for most computers. Find this file and copy it to the home directory. Find specific row and add the option /NODEFAULTLIB:LIBC as follow:

set LINKFLAGS=/dll /export:mexFunction /MAP %LIB_NAME%1.lib %LIB_NAME%2.lib /implib:%LIB_NAME%.lib /NODEFAULTLIB:LIBC

For compiling run compile.m. 
  

IMPORTANT:
----------
IT IS IMPORTANT to have set path to a directory where calimage.data file is located!!! Without this file, grabed image is always white.

Using:
------
write in Matlab:
   devinfo=giottoopen('LPT1');
   giottocal(devinfo);   //only if you want to calibrate the camera
   image=giottograb(devinfo);  //for acquisition

 another asquisition:
   image=giottograb(devinfo);  //for acquisition

Note:
-----
For calibrating the CMOS sensor is good to use half of white Ping-Pong ball.
