I had seen Juj post this code over on the retropie forum. I struggle to see the improvements myself, but im sure it looks better in person.

Have you tried it on a zero?

Is there a way to connect this screen with your pcb easily. This would further minimise unwanted red pcb.


Look what I found on AliExpress
http://s.aliexpress.com/IRrqY7re

if you have a look at this post....

https://sudomod.com/forum/viewtopic.php?f=25&t=5614


the boards were designed to be used with a 3.2" 18 pin ili9341 LCD, which dont come with a red board and are just bare LCD...
(you can just soldered the screen to the board, and ignore/avoid using the 0.8mm pitch connector)
(it can also be used with any size bare LCD from 2.2" to 3.2")



it may not be the cheaper option, but IMHO is a cleaner option...
also may not be the easiest option initially, but does offer quick attachment and release once everything is done....



.
one question. where do you get 0.8 mm pitch ribbon connector? just destroyed one screen trying to unsolder and using it for my GBA project.

not on zero, i think he confirmed over on youtube that code is hardcoded for RPI 3 gpu drivers.

On https://github.com/juj/fbcp-ili9341 he mentions
It might not even work on other Pis than the Pi 3 Model B that I have
Only one way to find out :D

may not work on the zero no. i'm hopeful I can get it to work on a CM3 though (which is basically a Pi 3) by specifying the alternate pins I want to use in the code header. I've forked it and will be having a play later on tonight to try and get it to work...

yeah i think it relies on being able to run on a core on its own, then the emulator can run on another core, so everything hops along nicely :)

This has been tested on a Pi0 W by Bluup on Discord Chat so that is that.

Don't contact me about obtaining my board files (as you will not get them). Don't contact me about any of my boards if they are sold out, they will be restocked as soon as I can get them.


Don't support thieves like ckliang who copied my AIO to resell and is now cloning the mintyPi, support the original creators and not the thieves!

Could someone give a little more details on the Pi0 performance? I am currently using one of these with the classic fbcp driver on a pi0 and get like 24fps max. On the gitpage they say the performance is bad compared to 60fps on a pi3, so how many fps can we expect when using a pi0?
