The last few lines of the TED-Kit 2 API C# source code given in the TED-Kit 2 V4.0.0 NXP software reference two libraries, which are "tk2d" and "tk2". What are those two names referring to? When I run the program on a windows form application, it says it is unable to load DLL 'tk2d' or one of its dependencies. Are there certain DLLs that must be referenced by the windows form application? And if so, which ones? The DLL tk2.dll cannot be referenced because it is invalid or unsupported. The programmer's manual does not say anything about referencing DLLs, but I am still confused as to what the last few lines of the TED-Kit 2 API C# source code are talking about.
