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.

TCP Server Example - How to use WPA3 device
I'm experimenting with the "pico/wifi/tcp_server/". It works as expected with a WPA2 secured network, however I can't figure out how to access a WP3 secured network. According to the Pico W datasheet the device supports WPA3. However the function cyw43_arch_wifi_connect_async doesn't seem to have the option to select WPA3. The supported options are CYW43_AUTH_WPA_TKIP_PSK, CYW43_AUTH_WPA2_AES_PSK, or CYW43_AUTH_WPA2_MIXED_PSK.

Pico and MPU6050 only outputs 0's
I connected the MPU6050 and Pico as shown in the wiring guide for the example code here and have also tried using a level shifter with this wiring setup.

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

Trouble Getting NeoPixel Libraries to Compile in C
Okay I abandoned both of those libraries and tried the simpler WS2812 example in the Pico SDK and I did get it working....finally.

Beginner question
For C++, you could look at the pico-examples on Github https://github.com/raspberrypi/pico-examples

I've looked everywhere online, and I wasn't able to find something like this, does anyone have any advice?
I don't know what you mean. There are dozens of tutorials on the frontpage of google. And just straight up a bt folder of projects for the pico w in the rpi github at https://github.com/raspberrypi/pico-examples/tree/master/pico_w/bt. have you tried that? If you haven't, then you need to work on learning how to use google because people aren't here to do work for you. If you have tried this and it didn't work then reread my previous post and ask better questions.
- So I started porting braids to the PI PICO and ended with a generative drum machine

Pi Pico driving an SPI display SSD1351 driver - corrupted image?
I'm sorry I don't use the pico-sdk so I'm not 100% sure of which method it'd be. A short lookup in the pico-examples repository brought me to this.

Turn on Pico W LED pin in C
The LED is controlled by a GPIO pin on the radio, not the RP2040. See https://github.com/raspberrypi/pico-examples/blob/master/pico_w/wifi/blink/picow_blink.c.

Embedded Rust Education: 2023 Reflections & 2024 Visions
Inspired by James Munns's call, and as 2023 is coming to an end, I figure it's a good opportunity to reflect and look forward to 2024. It's been a bit over 1.5 years since I embarked on my embedded Rust journey and it's been nothing less than exciting since. So here it goes.

In search of Rust projects to contribute
Because you are an embedded guy. There is the https://github.com/rust-embedded/wg working-group. Rust on embedded is really on a got track forward. There are many chips/vendors that are supported both in no std / std rust world, but still there is a lot of niche things where you can actively help to be the first to get it run in Rust.

Rust – Are We Game Yet?
To specifically answer your question, here:
* <http://www.areweembeddedyet.com/>
It currently redirects to:
* <https://rust-embedded.org>
Which doesn't really contain anything other than a link to <https://github.com/rust-embedded>.

Google announce secure Rust-based OS for embedded system
Then the Rust Embedded workgroup provides: - Direction on how to using generics and zero-sized types to achieve functional safety - svd2rust, which provides safe abstractions to peripheral access from SVD files and achieves this functional safety - The embedded HAL spec, which makes porting to different vendors/hardware easy - Peripheral access controllers and HALs for various vendors & hardware
-
What are your guys' thoughts on Rust?
The Rust Embedded Devices Working Group curates a list of useful embedded Rust resources, including Peripheral Access Crates (autogenerated from SVD files), embedded-hal Implementation Crates (hand-written libraries implementing the traits (interfaces) specified by the embedded-hal), and Board Support Crates.

Things you can’t do in Rust (and what to do instead)
Here's an interesting discussion, consolidated here. My view is you should use a restricted scope atomic (as best as can be supported) and interact with that through a handler struct. I.e. no global state.
- Semantic Versioning Will Not Save You
- Is there a embedded community/website where it is modern?
-
Would it be possible to run Rust on the new Raspberry Pi Pico?
Most of the issues are explained in EWG RFC 419. The TL;DR is that some resources need to implement Send to be usable from interrupts, but they must not be sent across cores.
What are some alternatives?
