I want to use an expansion MEM board

[JSanc.7]

I want to use an expansion MEM board and I followed this article: 

The problem is when I generated the code and tried to build the project, I found differents errors because in the 2 generated files there are a lot of variables undeclared, most of all are variables I'd never seen.

I'm going to add differents photos of the errors.

Could anyone help me? 

Thank you.
