What is pi core? Is it similar to Raspbian Buster Lite?Fraoch wrote: ↑Tue Aug 13, 2019 6:14 pm
Have you tried piCore? It is blazingly fast, even on a 1B/Zero. It's quite different than your usual distro, it boots core files from the SD card and runs entirely in RAM once they're loaded. You get a command prompt in 2-3 seconds even on the 1B/Zero. Packages are supplied as downloadable extensions which get written onto the SD card and loaded as needed. So it's fast even with their desktop GUI. I'm still learning and playing with it, it's amazing. I'd really recommend looking into this for the Zero.
I use 3.5" 480x320 LCD displays that mount to the GPIO block with Pi0?pi0W boards. Yes, the display is bigger than the Pi, but it does work nicely.
Is there a difference between screens using the GPIO pins and screens using the display ribbon cable?W. H. Heydt wrote: ↑Thu Aug 15, 2019 12:34 amI use 3.5" 480x320 LCD displays that mount to the GPIO block with Pi0?pi0W boards. Yes, the display is bigger than the Pi, but it does work nicely.
I've tried tiny core Linux before on older laptops.Fraoch wrote: ↑Wed Aug 14, 2019 1:33 amIt's based on Tiny Core Linux. It's very, very basic - far more basic than Raspbian Lite. But the beauty of it is that you install only what you need. The basic software loads from the SD card into RAM on boot. It runs entirely in RAM so it's very fast and doesn't write to the card.
If you need other things, you load them from extensions, which are either loaded on boot or loaded on demand from the SD card.
Trying to figure it out today and got a fast FLWM desktop, nano and the Dillo web browser running very easily. The Lynx web browser was a little harder. Installing software and mounting a Samba share was pretty easy, I just need to figure out how to put fstab into persistent storage.
It's very do-it-yourself and requires some work but you end up with only what you need.

By "display ribbon cable" I assume you mean using the on-board DSI connector. There is only one display compatible with the DSI connector. That is the RPF 7" touchscreen. 5" is kind the the transition point between displays that connect to the GPIO block and the HDMI port. When using a GPIO-connected display the resolution and refresh rates are...rather limited. IIRC, for a 480x320 display, the refresh rate is going to be restricted to around 20 fps.ProDigit wrote: ↑Thu Aug 15, 2019 12:39 amIs there a difference between screens using the GPIO pins and screens using the display ribbon cable?W.

I use the 3.5" displays as electronic name badges. Refresh rate is pretty much irrelevant.alphanumeric wrote: ↑Sat Aug 17, 2019 12:00 amMe personally, I've never been a fan of the GPIO connected displays. I usually have other devices connected that will cause a conflict. Plus I'm not all that fussy for small displays. I'd like to see some other options for DSI connected displays. 10 inch or bigger. Don't have to be touch screens, just bigger that the current 7 inch offering. Even a 7 inch with a higher resolution would be nice.
There is a more standard rectangular 800x480 pixels version of it.rpdom wrote: ↑Sat Aug 17, 2019 5:17 amWeird size...
It uses the DPI interface on the GPIO pins, the same as Gert's VGA666 board does although to drive a different interface. DPI is capable of 1280x1024 at least.
