lvgl VS micropython-micro-gui

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:

Hi there. I am an extreme beginner with python and programming generally and am trying to use a ssd1306 display with a tiny pico board with this (https://github.com/peterhinch/micropython-micro-gui) code library and cannot for the life of me figure out how to install this as there are few visuals and I am getting extremely confused by the instructions.

That post really resonated with me. I attempted making my own ESP32-based remote for controlling my media centre while I'm in my kitchen, or generally away from my laptop.

The nature of embedded with interrupts (e.g. from buttons) and trying to mix in MQTT events and nice multi-layered UI made me completely question my programming abilities.

I really wanted to have modals/pop-ups (e.g. to show current volume on change) and it ended up so messy. Not only it is about control flow but about memory too (as the author mentioned). I couldn't just store a stack of "screens" to fall back to.

I'm watching this library recently: https://github.com/peterhinch/micropython-micro-gui

It seems promising to solve many of the common issues that you get, once you move from simple static information display.
