So, I got my first Raspberry Pico :-)
I also got a 'Pico Explorer Base' device at
<https://shop.pimoroni.com/products/pico-explorer-base>
This thing has a st7789 screen. I got it to work with Python.
Now - I see that there is work done with the Pico and Ada - the
<https://pico-doc.synack.me> seems to be a good place to start.
I wonder if there is any port done already for this screen in Ada?
Google points me to some python and some c/c++ implementations (whereof
Pimoroni's Github has some)
I also came across uGUI <http://embeddedlightning.com/ugui/> which
loooks interesting. Same question there. Ada-port?
I hesitate to start translating one of the c-libraries - but
I probably will when time permits if nothing is already in place.

The Pimoroni Picosystem uses a ST7789 screen, I have a driver for it in picosystem_bsp:
https://github.com/JeremyGrosser/picosystem_bsp/tree/master/src
I didn't implement every feature or video mode that the controller supports, so you may need to modify it to suit your needs.

Perfect - just what I was looking for - thanks.
And thanks for the effort of bringing Ada to the Pico

I have an Ada binding [1] for the excellent lvgl GUI library [2]. You can get it from Alire: [3].
It is not in a very beginner friendly shape, but it works. I am trying to do a new version that should be easier to integrate into existing project.
Don't hesitate to say hello on the Ada Gitter chat if you want an little help setting it up.

Interesting. When things at work calm down, I'll look into it
(so - I'm just investigating for later use)

Ok, thanks - good to know
