I really want to use the 7 or 9 inch tft display because I think it would massively simplify a project while also adding in a new element that I like to explore. I currently have a teensy 4.0 and I would like to use it to build a kerbal space program controller. The issue is how do I connect to the display and if anyone has any tips on making a gui that would also be amazing.
We have several TFT displays available, which one are you wanting to use?
We only have tutorials for our SparkFun originals, like this product: https://www.sparkfun.com/products/15143. You could try reading through the Hookup Guide for that product to get more insight on what you want to build.
