Hi Santana,

Sorry, I don't have the hardware with me to check. But I suggest you to Google the error. You'll find normally what's it about. It worked to me fine, so I can't help more about it.
"SOMETHING was not declared" means normally some library missing I think. Check that you installed all libraries, and you use the right versions.

Good luck!

Hi can you tell me which way is better and bring me less problem in order to use makeblock with my raspberry pi;
1- using me shield with meOrion
2- using megapi with wiring
thank you

You need only arduino ide to compile the program use this link https://github.com/Makeblock-official/PythonForMegaPi there you can find official library for makeblock. if you compile firmware for megapi, it is not working. i think there is a problem with the library. i didnt find anything about the errors and wiring in google.
thank you
