It appears to me that the startup logo though referred to in the application source files is actually part of the library project, is this correct?
Yes, the logo is in the library(not ST library).
So here again I can’t actually modify this part of the application…
Yes.
That’s cryptic, do you mean look closer it’s actually in there or do you mean I can’t change the logo screen using this source code?
I think you mean “NO” a user can’t change the logo screen.
Sorry, I didn’t say clearly. I mean you could not modify logo at present.
