Check here for compilation and usage: http://jcornuz.wordpress.com/2007/11/18/use-colorvision-spyder-to-produce-an-icc-monitor-profile-under-argyllcms-linux/ Take care, Joel Hi there,

These are ArgyllCMS which is Graeme Gills project and LProf (if you use CVS). Both have been tested with the Spyder 2 and a number of other meters. ArgyllCMS is a set of command line tools that include monitor calibration and profiling functionality. Very powerful but not very user friendly. LProf is a Qt based GUI ICC profiler that is much easier to use but at present has somewhat simplistic display calibration and profiling algorithms. Both run on X11, Windows and OS/X platforms and can coexist on the same machine. At this point the Spyder 2 code is not very mature. It works but is temperamental at least on my machine. This should improve as the drivers mature. Devices that have been supported for longer such as the EyeOne Display series, EyeOne Pro and DTP-94 are working very nicely and the Huey which was added to the library after the Spyder 2 is still problematic (IE. mostly not working) at this point.

The light sensors are TAOS TSL237's, which are a light to frequency converter, so the readings are in fact integrated counts of the number of transitions of their output. There are a total of 3 x 8 x 24 bit values (72 bytes) for each reading, allowing for 8 sensors, the first of which isn't populated. The three numbers for each sensor are the 1MHz clock start count, end count, and integrated frequency transitions since the last reset. For doing a CRT reading the refresh frequency of the display needs to be established using the c2 and c3 commands. Converting to XYZ entails scaling according to the integration time, and then applying the 3x9 floating point calibration factors read from the Serial EEPRom during the initialization sequence. There is also an additional 3x9 calibration factors that allow for non-linearity. And of course, the Xilinx XCS05XL PLD needs it's pattern loaded before you can do anything. If you want any other details, I can send you the source to the driver I've just completed :-) In fact the Spyder II has 7 sensors with different short wavelength cut-off filters, as a look inside the unit quickly indicates.
