Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How common are 16-bit MCUs ?
A bit off topic, but tiny-json exists specifically for embedded platforms, so I wouldn't roll my own allocator just for this: https://github.com/rafagafe/tiny-json

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...

Interfacing SPI LCD with Zynq 7020
I'm trying to interface SPI LCD (ILI943) with Zynq 7020 (PYNQ-Z2 board) and LVGL embedded UI libary. And considering between two approaches:
What are some alternatives?
cJSON - Ultralightweight JSON parser in ANSI C
