Cruising a WWP15 and upgrading soon!

[Pottersailor3]

I am new to cruising and to posting on forums of this type. I do 3D printing and design my stuff in FreeCad. I fiddle with electronics and have taught myself enough C programming to make some Arduino magic and enough python to get myself into trouble. My current project is a "Cyber-Deck" which is a small computer in a case (home made laptop) but this will be dedicated to Chart Plotter use in a water tight case. My current problem is changing the screen orientation 180 degrees on a 7 inch TFT display. I am hoping after posting here to find a thread with my answer. Let me know if you know right where I should look. Thanks.

BTW: I am in the market for a Cape Dory 25 or 26 with trailer. Or very similar boat. Thanks.
