Ask HN: Nobody interested an open hardware iPod Nano?
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...

Co-ordinates when programming a screen - trial and error?
I haven’t used these personally myself, but have a look at using LVGL with Squareline. I used photoshop for designing layouts for my (simple) screens in the past and the only issues I’ve had regarding replicating my designs iirc was with text (as you mentioned) and rounded corners.

Release v0.5.9.10 · embox/embox
Embox is a configurable RTOS designed for resource constrained and embedded systems. Embox main idea is using Linux software without Linux. (https://embox.github.io/ ) If you want use complex Linux Software and Linux is huge for your goals. Embox is the best idea, as I think. For example Embox is the only RTOS that allows to use OpenCV on Cortex-m MCUs https://www.embedded.com/benchmarking-opencv-on-stm32-mcus/

Embedded software testing
In Embox (https://github.com/embox/embox ) we use several testing levels to check different parts including hardware. We designed unit test framework on C and can use it to check hardware (https://github.com/embox/embox/blob/master/src/tests/spi/imx6_spi.c). We also try to develop peripheral independent code. We created libraries and use files for access to peripherals that allows using a command-line interface to test hardware. And finally, we have a regression testing framework. It bases on 'telnet' and 'expect' (https://github.com/embox/embox/tree/master/scripts/autotest). I'm sure that UART can be used instead of telnet

which modbus c library do you use?
Embox (https://github.com/embox/embox) is a configurable open-source RTOS. Its main idea is to use Linux software everywhere including MCU or develop software in a convenient environment. In other words, you can use wished Linux software without "heavy" Linux kernel therefore you need small resources. In the article, libmodbus is used on STM32F4-discovery. Embox allows using of such complex Linux software as OpenCV on STM32 (https://www.embedded.com/benchmarking-opencv-on-stm32-mcus/ ) or Qt (https://youtu.be/9rA\_sHrQjjE)

Choosing an RTOS
Yes, it is a very fast development speed especially if you need rather complex functionality. As for other questions, the project is more than 10 years and more than 100 contributors (https://github.com/embox/embox/graphs/contributors ). I think it will actively develop.
You should look at Embox (https://github.com/embox/embox). Its main idea is to use Linux software everywhere including MCU. It looks like an embedded Linux distributive where you can choose necessary modules, but unlike Linux Embox's kernel, standard C library, TCP/IP stack and so on also configure while compilation. It allows on the one hand run on EFM32 with 32kB flash 4 kB RAM (https://anton-bondarev.medium.com/embox-on-efm32zg-stk3200-board-how-to-run-rtos-on-mcu-with-4kb-ram-26a82dc7b9d9) and on the other hand you can use TONs Linux software for example OpenCV (https://youtu.be/7QjfgEPCLiw )
