Delete that folder & contents.

4

Close the IDE, restart it and try to recompile.

@missdrew

Delete that folder & contents.

then close IDE and add library again try to compile same problem

6

I never said to add the library!

Unfortunatelly I have no idea what your new error is, please post the FULL error.

7

@missdrew
is it possible to test it by your side and tell me steps, thanks

8

NO - YOU post the error you have now. Also, where did you download the library from?

9

@missdrew

from here https://github.com/arkroan/CT1642

10

On line 536 of CT1642.cpp change 'DATA_p' to 'DATA_P'

@missdrew
it is compiled correctly, thanks for your help
