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.

Raspberry Pi Pico W: your $6 IoT platform
Espressif is years ahead.
Original RPi-pico has only few one-ups on ESP - BSD-licensed bootrom [0] and PIO.
PicoW doesn't have any, at all. Disappointingly lazy move from pi foundation.

Another Vulnerability in the LPC55S69 ROM
I would think that the bootloader code wouldn't use any funky IP blocks - it's not some sort of driver code into which applications call, it's just a special application that runs before anything else. It has to be able to talk UART (or some other interface), check signatures, and write flash. All of these the user code can do as well.
There are many "user-space" bootloaders as well for various chips. The factory bootloader is only different in that it sits in ROM. For example, RP2040 ROM bootloader is here https://github.com/raspberrypi/pico-bootrom
- Why does the pico accept Microsoft uf2 format rather than raw ARM machine code?

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

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.
