+* 2015-05-09	timolang@gmail.com	0b5173e	Added reference tracking.
+* 2015-05-15	timolang@gmail.com	27c09ba	Redesigned main menu. Moved stuff from pixytest to a new helper file and to the new "photo mode"-screen.
+* 2015-05-25	timolang@gmail.com	6a61769	Reimplemented pixytest screen. Added a lot of Test-Buttons.
+* 2015-06-01	aaron@duckpond.ch	caa7b5c	Added IRQ for user button, fixed some touchproblems.
+* 2015-06-03	timolang@gmail.com	74aa186	Made pixy_test screen working again. Had to disable pixy_service. Recalibrated initial touch values.
+* 2015-06-07	timolang@gmail.com	c87220d	Renamed pixy_helper to pixy_frame. Updated docu of appliaction. added doxygen comments to pixy_{frame,control}.h

+Prerequisites:
+- Qt5 for Windows (provides C:\Qt\5.4\mingw491_32  and C:\Qt\Tools\mingw491_32)
+- Mingw msys-base (provides C:\MinGW\msys\1.0 and make, find )
+- Boost (check emulator\libs\boost)
+
+Steps:
+- Open up the msys shell using the batchfile
+- Navigate to the emulator folder of the project
+- Source the qt binaries (qmake, gcc, g++) by executing 
+  export PATH=$PATH:/c/Qt/Tools/mingw491_32/bin:/c/Qt/5.4/mingw491_32/bin
+- navigate to libs/Pixy and execute make
+- navigate back into the emulator folder and execute make
+- this should generate you build/emulator.exe
+
+Starting:
+- Extract windows_dlls.rar to the build folder
+- Copy the emulated folder into the build folder
+- Make sure that you installed the pixy usb driver (e.g. by installing pixymon http://cmucam.org/projects/cmucam5/wiki/Latest_release)
+- Start emulator.exe
+
+Pitfalls:
+- libstdc++ must be provided by qt. do not use one of msys or mingw. you will waste hours with debugging of the make process
+
+Sources:
+- libusb for windows was taken from https://github.com/charmedlabs/pixy/tree/master/src/host/windows
+- Boost was compiled from sources, using http://andres.jaimes.net/718/how-to-install-the-c-boost-libraries-on-windows/ and http://www.boost.org/doc/libs/1_58_0/more/getting_started/windows.html
