Hello, I am in the middle of trying to make a smart coffee maker for a school project. The only aspect of this that has been difficult is getting this display to work. It is a transparent OLED manufactured by Sparkfun. I will attach pictures showing why that is necessary for the project, plus it looks so cool!!! Only issue, it is such a pain to program. Right now, I am trying to get a button to update the screen with new text. Seems pretty easy, right?
Well, whenever I use pinMode(buttonUp, INPUT), which is in setup, the loop function does not run at all, nothing displays on the screen after the circleTest(). If I comment out the pinMode, the display goes on to show the text I programmed. Here is my code:
#include "HyperDisplay_UG2856KLBAG01.h" // Your library can be installed here: http://librarymanager/All#SparkFun_Transparent_Graphical_OLED
#include <hyperdisplay.h> // The rest of the Layer Cake: http://librarymanager/All#SparkFun_HyperDisplay_SSD1309
#include <HyperDisplay_SSD1309.h> // http://librarymanager/All#SparkFun_HyperDisplay

I know this is very poorly written, I just need it to work right now, I can clean it up later. If anyone has any suggestions for how to get this button to work, it would be greatly appreciated!!!
Also for anyone asking why I have 2 identical "Start" functions, if I run the original one more than 1 time, it won't execute. Still trying to figure that out too.
My main goal is to have two buttons to change the temperature readout on the display, and ultimately regulate the coffee maker to that temperature. Thank you for your help!!!
