No, sorry, doesn´t work that way, but you gave me a great idea.
I commented the "Wprogram.h" and added the HardwareSerial.h library. The new headers definition in the bsp.cpp looks like this:
#include "qp_port.h"
#include "dpp.h"
#include "bsp.h"
//#include "Wprogram.h"
#include "HardwareSerial.h"
Now it compiles, :). Whatever, I don´t understand why it didn´t work with the original declarations.
Thank you for your help.
