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.

Anyone want to help create a Free and Open Source AlphaSmart Neo?
Some ideas can be borrowed from here: https://github.com/fdivitto/FabGL

Learning programming on TTGO VGA32 (based on ESP32)
I would like to use TTGO VGA32 as a programming environment for children to learn how to code like it's 1999. Only basic tools, a code editor and a compiler/interpreter, no web browser, no Stack Overflow, no code completion. See this article for a rationale. Now, what developer environment would be the best fit? FabGL provides PC Emulator with a selection of OS-es: CP/M, FreeDOS, MS-DOS, SvarDOS, ELKS, GEOS, GEM. Which would be the best OS? Apart from BASIC and Turbo Pascal/C++ or Watcom C++, which useful dev tools for 80186 should it contain? Micropython, Lua, Wasm3? What do you think of it?

Looking for variable to store strings to display a message on LEDS
You will want to follow the advice given by u/Stitch10925 and u/Ikebook89. If you take a look in the src/fonts folder in the FabGL library you will find many bitmapped fonts including a 5x8 and a 6x8 font. Either of these sound like exactly what you need.

With Pi boards being harder to find, I've been looking at alternatives. I think the ESP32 might be an interesting option.
https://github.com/fdivitto/fabgl is pretty much everything you'd ever want from an ESP32

Bluetooth to USB Audio bridge
Implementing the required USB host interface is another hurdle, but tinyusb seems to have sorted most of that out, except that UAC2 is implemented as a device while you need a host.
- So I started porting braids to the PI PICO and ended with a generative drum machine

USB CDC: Multiple Virtual COM Ports
Have a look at TinyUSB. It supports the STM32WB and demo programs for the Nucleo-WB55RG. It even offers an example for dual CDC ports, so very close to what you're looking for.

Looking for well written, modern C++ (17/20) example projects for microcontrollers
Second: Distrust, misunderstanding, and out of date opinions of C++ in embedded spaces. I often see "compatibilty" thrown around as a goal for using C and not C++, but for most modern embedded systems, C++ compilers exist and are (usually) well tuned. Arm is a shining example here*. C++ is more optimizable than C as the intent can be clearer to the compiler. C++ constexpr and templates are a godsend for embedded systems, and I used both heavily in my recent arduino and pico testing. I combined both of them for a really cool experimental USB interface descriptor builder that runs at compile time and avoids the need to count byte sizes, but I gave up on it when the maintainer said C only, despite the fact that C can't do that. I was similarly disappointed when the pico "C++" was C only, as there was no backwards compatibility necessary.

Pico + CH559 = USB Midi host?
I looked at this but the fork seems to have had a lot of problems from looking at the PR: https://github.com/hathach/tinyusb/pull/1219

Badger 2040: tiny kit ereader
I think a better solution might be to use a USB flash drive in the usbc port. Unfortunately micropython and circuitpython don't support this (yet), so you'd have to use c++ https://github.com/hathach/tinyusb

ESP32-S3 Update via USB?
It's possible to make the s3 be a mass storage device via TinyUSB. https://github.com/hathach/tinyusb/tree/master/examples/device/cdc_msc_freertos
- Microcontroller that can read voltage?
- how do emulate a keyboard over usb? wherever I look I only see libraries and tutorials on how to use the eps32 as a Bluetooth keyboard not a wired one
