Hello all I am trying to attempt a project with the fingerprint scanner (GT-511C1R), however I think I my board is not transmitting to the FPS or vice versa. I'm attaching the header and source files and examples I found that I’m playing with and also links to what I have tried. Any help is greatly appreciated.
