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.

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.

higher channels not working on nRF24l01+PA+LNA radio units
Yeah. If you have the main RF24 library installed it's under the examples in "scanner"
-
wifi/location automation programming?
No unfortunately I don't. One of the cool things I did learn about the NRF24L01's though is that on the main page run by the guy that is like THE author of the library that everybody uses with them; He has a sketch that you can run and it will scan all of the frequency channels it supports and give you an ascii graph showing which ones it saw signals the most on.

Which one is correct?
Here is THE library on which 90% of everyone else's libraries are based off of. This guy quite literally wrote the book on these devices. Bookmark this link and treat this guy as the source of truth for all things related to the RF24 series. I recently discovered 8 NRF24L01's that I had stuck away and I've been playing with them for about the past two months and this is my go-to website for anything I want to know about connecting them and using them. 🙃

Help me ASAP!!!!
That's right. Just like Wifi and other radio comms have the ability to vary which specific frequency they make use of, the RF24 line and others give you the ability to choose the default channel. I think each of the available channels is about 100Hz away from each other. Here is the main web page by the author of pretty much the go-to library for the RF24 series of devices. One of the projects he has listed there (if I remember correctly) will go through all of the available channels and give you a psuedo-graphic representation of how much interference it is seeing on each channel in order to hep pick which channel to use so you aren't fighting it out with all of the devices your neighbors might be using with the various devices they have.

nrf24L01+ scanner porting from cpp to micropython
I started playing around with my pico and an nrf24L01+ module this week and I was thinking to just hack this a bit more, starting from porting the https://github.com/nRF24/RF24/blob/master/examples_pico/scanner.cpp scanner to micropython.

Help with nRF24l01+ library
I used the RF24 library and official datasheet as a reference.

My first project! I know it's just a wireless servo and my code is totally crooked, but you gotta start somewhere right! i should've gotten this stuff so much sooner...
Which Library did you use to interface with the NRF modules? I've tried the RadioHead library and this one but haven't been able to get a successful send/receive between my two Arduinos.

I found an easy way to test 2.4GHz downconverters for RTL SDR using a nRF24L01 module
But I didn't know if it worked. I saw a lot of different random signals, but I had no way to know if it was just amplified noise, nor I had a way to know if the downconverter frequency was exactly 2.4GHz, or something else. I have a few cheap nRF24L01 modules around, and plenty of 3.3V Arduino boards, so after a quick read on the nRF24 library (https://github.com/nRF24/RF24), I had a super simple generator running using the carrier wave function of the nRF24.
