I second that. Some pictures on inet show pin 18 as well, but the chip does not seem to have GPIO18.

Hah, I just converted and imported your library into diptrace, designed something and tested gpio18 - nothing happend :) As @far5893 and @positron96 remarked there is no gpio18 but gpi16.

Thank you so very much for the time you spent to design this library! It saved me a lot of nerves and time! Thank you!
