It was time for a nice GUI.
Well a really nice GUI on 2cm² is hard to realize but at least I could make everything good readable.
Due to the lack of different fonts and sizes in the default micropython library I searched for something easy to implement.
And I found it! Peter Hinch has written a really nice library in micropython hat is based on the official drivers for the frame buffer and the SSD1306 OLED display I use.
With some modifications in the code it just runs perfectly on my Pi Pico!
So, if you need a good GUI library that offers some fonts in different sizes, nice widgeds and is portable to many microcontrollers check his repo!
Now, here are some pictures of my 'pages'. With a push button it is possible to move from one 'page' to another.
