lvgl VS rt-thread

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:

The IoT Contest 2023 is organized by Open Source RT-Thread Organization and we Partnered with NXP Semiconductors, STMicroelectronics, and WCH Electronics.

The GD32VF103 is also supported by RT-Thread.

There's a bunch of documentation (in english) at https://github.com/RT-Thread/rt-thread/blob/master/documenta...

One thing that stands out is that one of the selling points would be the inclusion of middleware etc.

  Internet of Things related software packages:

Open Source RT-Thread IoT OS Project has hit 12000 followers on social media platforms. THANK YOU ALL FOR THE SUPPORT!

So RT-Thread IoT OS partnered with LVGL, STMicroelectronics, Nuvoton, and NXP to bring this contest, opening an opportunity for embedded developers that come from everywhere to explore more possibilities with embedded GUI.

Now, let's get it on the Open Source RT-Thread operating system to demonstrate how rust can be used for embedded development.

There are consolidate steps to transplant the OS onto other hardware platforms, which includes various chips of the same architecture, as well as of different architectures. This article will walk you through how to port OS to many various chips and we learn from open source RT-Thread OS as a case study.
