I had a discussion recently on how to implement a GUI on an embedded platform I’m designing. One interesting idea was to port Qt to run standalone on the ARM MCU. How hard would this be and what would I need to rewrite an and/or implement? What would the hardware requirements be? In terms of flash space and CPU speed. I was looking in to Cortex-M4 MCUs. I’m going to use a 800×480 graphical color LCD screen.
I would not want to use Linux because I feel that is a bit bloaty for a simple GUI. Maybe some RTOS in maximum.
