crankshaft VS lvgl

But, according to : https://github.com/opencardev/crankshaft/wiki/Android-Auto-Wifi

It's pi focused apparently https://github.com/opencardev/crankshaft/wiki

3)The route that I ended up going was to build my own unit with a Raspberry Pi running Crankshaft to run Android Auto and a 7" touchscreen that I mounted magnetically to a phone mount that inserts in the CD player. Doesn't look OEM butif you manage cords it looks pretty clean and works well. Also cost me under $100 and I can remove it easily any time I want. I'm a little techy so it wasn't too hard - there are tons of videos out there that will walk you through the project.

How about this? https://getcrankshaft.com/

Your other option, which I actually use in my R56, is to utilize the Crankshaft project with a Raspberry Pi and a generic 7" touchscreen from Amazon. I mounted mine with a magnetic mount from the CD drive and power it through the aux power port. Mine works both with wired and wireless Android auto, with very few glitches. If you're techy at all it doesn't take long to set up.

So here is the thing: The iPod Nano 7g is from 2012. I've seen many people designing custom PCBs and releasing Kickstarter projects for custom audio players[5] or game handhelds[6]. I know Rockbox (which is great, but its lacks support for Wifi and Bluetooth AFAIK and just does not compete with the UX of iPod's audio book features in my opinion) and iPod Linux. 10 years ago someone even reverse engineered the iPod Nano 6g display[3].

Although I'm not skilled enough in PCB-Design, after some research I found the Lilygo T-Display S3 Pro[4] based on ESP32 S3, which would be the size, but lacks audio and OS. There is also the Mango PI CyberPad[7], which looked interesting, but maybe is already too clunky.

Programming wise, LVGL[8] may be a good framework to develop a modern and efficient UI - at least it looks promising.

So, why is nobody interested in recreating an iPod nano like device? It should be doable with modern tech, but Phones have completely taken over the marked...

LVGL is a graphics library used mostly for embedded UI's. Main website: https://lvgl.io/

Popular embedded UI library

If you need something written in C and very tiny, I recommend LVGL https://lvgl.io/

The factory code uses the Lvgl graphic library. https://github.com/lvgl/lvgl

I'm trying to interface SPI LCD (ILI943) with Zynq 7020 (PYNQ-Z2 board) and LVGL embedded UI libary. And considering between two approaches:
