What's good to learn / read and where to find it ?
When i would know some more about alphanumeric characters and custom graphics programming for microcontrollers with displays (0"-4")

Thanks in advance

Answer 1

I was hoping to find some general information, like how to move grafic around the display with out making new grafic for each frame
I have a 1.8" display with a ST7735S chip

Answer 2

Depends on what you want to achieve. Alphanumeric characters are usually simply ASCII characters (just search for: ASCII table). Custom graphics depend a lot on the display you are using.
Some displays only support ASCII characters, some a bit more. Does your display have a library or a decent API description?
