Hey there,
I have to do a project for school, where I have to program a 4x4x4 RGB LED cube so that I can choose the colors.
The model is Iduino AD060, which needs which needs an Iduino ST1149 driver board. The cube was already built by my teacher. I have absolutely no clue how that is done so I could only give you this information.
Manual of the cube: http://www.produktinfo.conrad.com/datenblaetter/1500000-1599999/001525427-an-01-en-RGB_CUBE_KIT_WITHOUT_DRIVER_BOARD.pdf
A lot of it is about building the cube, but I don't need that.
Manual of the driver board: http://www.produktinfo.conrad.com/datenblaetter/1500000-1599999/001525450-an-01-en-8_X_8_RGB_MATRIX_DISPLAY_TREIBER_BOARD.pdf
I don't know if the code there has anything to do with my project, though.
At the end of the manual of the cube, there is a sample code which I copied, but there are various error messages when I compile it. I hope I installed the Colorduino library correctly. Here's the code:
#include <Colorduino.h>

I don't understand everything, I only have some experience with Gamemaker Studio, so this is something entirely new for me.
These are the error messages:

I really need help with what I have to do now. All I need to do is setting the colors of the individual to what I want.
Edit: Sorry if this is not the right page but it's my first time on this forum.
