Custom TFT Button Guides?

Can anyone point me to a guide to coding buttons and menus for my TFT50?

I’ve found several on pi integration with custom buttons there, but no much in depth for the TFTs. I’d love to get the V1 marlin menu options on the touchscreen as well as a second home location button on the screen. Possibly even an instant feed rate button slow button when I hear the router bogging down.

If my better option is to suck it up and just buy the pi, please don’t hesitate to say so.

This helped shed light for me. My approach was wrong and needed to think of the TFT as a separate device… I think… anyway… check out LOKI’s page here and if you are 1/2 decent at hacking code, this may help get you started hacking the TFT:

modify this link to work by taking out the spaces… forum won’t let me post links

Obviously, you need Visual Studio and Platformio and all that…

Thank you for the redirect!
