Hereby we give the source codes of the project as open source.

The microcontroller source code you can find here http://www.uploadarchief.net/files/download/quad.bas  while the C++ main program is here http://www.uploadarchief.net/files/download/unit2.txt. When you feel the need you can search to some mathematical formulas in the C++ source which were extracted from the WJ8888 manual and descriptions.
If you look at the formulas you get some idea of the awesome magical design using only plain TTL logic without any microcontroller aboard! Great job WJ.

Because of the complexity to compile and build the project we can only provide the executable alpha version to have a look.
Microcontroller source is available in both bas (Bascom) and hex (Machinecode) format.

In no event shall we accept liability in any way when using this software. Please notice that this software is just a part of the project and that a high skill in electronics and software is needed to make the project succesfull.
