Well, something's happening. The thing is, I can't make sense of all the DSI init commands in the example code. I just don't know how the sequence works. Having spent about an hour reading data sheets and still not really understanding, I removed a load of the init commands (which aren't meant for this screen), and I got this:




then I removed some more, and now I have this :D

carl0s:
Now I have added in a command, and it works as per the data sheet. Yay. MADCTL, x-mirror, etc.

:D

carl0s:
So close now.

I think all that's wrong is the GFXMMU thing that basically manages memory (framebuffer) usage for circular displays. It chops off bits or something. I dunno. Well anyway it all looks good so maybe I should move onto the StEmWin stuff.

I realise you now have your boards back (and they work! awesome!  :-+ ) so it's probably a bit too late, but... why do you have thermal relief on your stitching vias?

What's that then?? :)

Is that something to do with the vias looking like a cross-hair? (I have no idea why that is.. Altium just did that).
