Build error ATmega32U4 about md_cubo HOT 2 CLOSED

If I comment out "#define TEST_MODE 3" from "USBCore.h" then I get the following results:

After removing all the settings files, except for the JC from the src-folder and changed the SPI-pins in the MD_Cubo_8x8_jC.h-file, I finally is able to build and load the µP. :) :)

from md_cubo.

The issue is caused by the define TEST_MODE being defined in both the MD_Cubo library (specific for JolliCube class) and the users's other included library (USBCore).

TEST_MODE is defined and used once only in the JC files, so the easiest user fix is to rename this in the JC header file and the JC code file to something different (eg, TEST_MODE_JC).

As this issue is very specific and affects a very small subset of users, affected users should implement the workaround above.
