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.

Just putting my hand up to say that MicroPython is awesome (and runs on the RP2040). https://micropython.org

Lilygo T-Deck: 2.8-inch IPS LCD display, mini keyboard, and ESP32 processor
Gah, I just ordered one on impulse [1]. I've wanted to build out a WiFi PDA for quite some time now and I like this hardware.
I'm quite liking the idea of running tulip MicroPython [2] on it, or going back to pure MicroPython [3] and writing some drivers. Apparently something like ampy can be used to upload/download Python files [4].
Threads could be quite exciting for running multiple programs at once [5], although I have no idea what it means for two programs to fight over GPIO! It does seem as though MicroPython can only utilise a single core [6].

about microprocessor
If you really want to engage in the travesty that is shoehorning a high level scripting language into an environment that has 512 bytes of RAM and less clock cycles than an electric toothbrush, there is micropython.

CAN Bus with MicroPython
There is some work to implement a common CAN interface in micropython but it's some way off yet: https://github.com/micropython/micropython/pull/13149

Show HN: MicroLua – Lua for the RP2040 Microcontroller

There's an iperf opkg pkg, or is it just netperf (which works with fluent)?

Ask HN: Embedded Scripting Options for Microcontrollers
Needed for hobby project, maintained by very small team. Haven't decided on specific microcontroller. Needed for general bit-banging, speed and code size are not priorities.
So far have considered MicroPython [0] [1] and Lua [2] [3], but open for suggestions for others.
What are experiences?

Arduino or python
Python is also a general-purpose programming language. It's typically used on desktop / laptop computers. But Micropython is a variant that can be used to program embedded devices.
