Help porting mcu-backend to different display.

[JaminMartin]

Hi, I had a hopefully quick question.

I was wondering if there were any guides on how to port the pi-pico printer demo to a different display - or how to get started with it.

The display I have is a SPI TFT 3.5" LCD Touch Module ILI9488 and I would like to try get the printer demo running on it. The waveshare boards are limiting in their application scope so I would like to get the demo up and running on a detached screen.

There is a display driver for this display, so I can replace the st7789 display driver, but I am unsure about the touch aspect of this.

I am relatively new to embedded development so any guidance is much appreciated.

Cheers!

The documentation/guide we have is on this page: https://docs.rs/slint/latest/slint/docs/mcu/index.html

But for the touch, you'll have to search online what is the touch controler and hope there is a driver for it. If there isn't, it is usually not too hard to write a touch driver if you find a C implementation, or a datasheet.
