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.

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.

FuryGpu – Custom PCIe FPGA GPU
The RP2040 is a great MCU for playing with graphics as it can bit bang VGA and DVI/HDMI. There's some info on the DVI here: https://github.com/Wren6991/PicoDVI
I wrote a couple of articles on how to do bit banged VGA on the RP2040 from scratch: https://gregchadwick.co.uk/blog/playing-with-the-pico-pt5/ and https://gregchadwick.co.uk/blog/playing-with-the-pico-pt6/ plus an intro to PIO https://gregchadwick.co.uk/blog/playing-with-the-pico-pt4/

Video Game Module for Flipper Zero
A few years back someone was bit banging DVI and 720p 30fps video straight off the RP2040 GPIO pins with just inline resistors between not and the HDMI cable.

VGA driver using PIO and DMA on the RP2040
I have the Adafruit DVI board and have been hacking on it some. It's more fun than should be allowed.
There's a project to get this running using Rust[1]. Currently it outputs the blue channel with sync, but has trouble with the other two channels. I don't have a hardware lab with scope, logic analyzer, etc., so it's not easy for me to debug.
In the meantime, I've been doing some experiments in the C codebase as well[2], mostly in the direction of proportionally spaced bitmap text, using the fonts in the X11 distribution.

There is even bit-banged DVI library for pico.

Show HN: PicoVGA Library – VGA/TV Display on Raspberry Pi Pico
Apparently, there is a digital video output project for the RP2040 already out there [0]! As for why digital video is more rare, it is because the common digital video formats are higher bandwidth and require higher signal integrity.

Least resourceful 18 year old air defense ukrainian soldier with basic coding abilities
I've seen people implement DVI with PIO, and I'm sure basic missile commands wouldn't be as bandwidth-intensive as that.
- Is a Raspberry Pi Pico able to play video on a spi-tft screen?

Help understanding current-mode and TMDS logic in DIV/HDMI.
For example this guy (https://github.com/Wren6991/PicoDVI) essentially 'bit bangs' CML. Sure its not a completely compliant implementation, but it's pretty close... In his case using a push pull with 3.3V/0V. I don't know how he's getting a 0.8V swing.
