It is not possible to compile the downloaded source-code from OpenRobertaLab program with the Arduino IDE.
Remark:
Simple program like LED blinky compile fine, by using //#include <NEPODefs.h>. NEPODefs.h is not necessary for simple programcode.
Program which used any display like OLED1306 required the header file.
I found the NEPODefs.h header file: https://github.com/OpenRoberta/arduino-resources/blob/master/RobotArdu/libraries/RobertaFunctions/NEPODefs.h
Do I use the incorrect header version for the Arduino IDE?
Error output:
new.cpp.o (symbol from plugin): In function `operator new(unsigned int)':
