Interesting new micro-controller board and custom chip from Raspberry Pi: Raspberry Pi Pico.
It is programmable with Python and C/C++. Cross-platform toolchain for development on Windows, macOS, and Linux — including, naturally, the Raspberry Pi family itself Supports TensorFlow Lite.
Raspberry Pi is looking to do for the microcontroller market what they’ve already done for single-board computers with the launch of the Pico. The board — priced at just $4 — is based on the RP2040, a dual-core Cortex-M0+ processor designed in house. It designed to be easy to taken into use.
Announcement at Facebook says:

Kevin O’Connor’s Can2040 Brings a PIO-Powered CAN Bus to the Raspberry Pi Pico, Other RP2040 Boards
Running on the PIO and borrowing some cycles from one of the two Arm Cortex-M0+ cores, can2040 offers up to two CAN bus implementations.
https://www.hackster.io/news/kevin-o-connor-s-can2040-brings-a-pio-powered-can-bus-to-the-raspberry-pi-pico-other-rp2040-boards-2caf05c0808d
“The can2040 project is a software CAN bus implementation for Raspberry Pi RP2040 microcontrollers,” O’Connor writes by way of introduction. “It enables an RP2040 chip to implement [a] CAN bus using a standard CAN transceiver chip. The code supports reading and writing CAN 2.0B data frames at rates up to 1Mbit per second.”
The project takes advantage of a surprisingly powerful feature of the RP2040: its programmable input/output (PIO) blocks, which allow up to eight simple real-time state machines to run separately to the two Arm Cortex-M0+ cores. O’Connor’s CAN bus implementation doesn’t run exclusively on the PIO blocks, however, but spreads across one of the RP2040′s two Arm Cortex-M0+ cores too.

How to run a webserver on Raspberry Pi Pico W
https://www.raspberrypi.com/news/how-to-run-a-webserver-on-raspberry-pi-pico-w/
We are in fact going to build a RESTful(ish) web server to control our LED.
I’ve chosen to attach an external LED to GP15 of our Raspberry Pi Pico W, but you could just as easily use the on-board LED for testing things out. Open up Thonny, and upload the following Python script to your Pico W. If you haven’t used MicroPython and Thonny before, full instructions on how to do that can be found in the Raspberry Pi Pico Python SDK book.

https://hackaday.com/2022/08/01/self-hosted-pi-pico-development/
Older readers and those with an interest in retrocomputing may remember the days when a computer might well have booted into a BASIC interpreter. It was simultaneously a general purpose device that could run any software it would load, and also a development environment. Not something that can be said for today’s development boards which typically require a host computer on which to write code. Have we lost something along the way? Perhaps an answer to that question can be found in [lurk101]’s self-hosted development environment for the Raspberry Pi Pico.
https://github.com/lurk101/pshell
A tiny Raspberry Pico shell with flash file system, Vi, and C compiler.
Credit where credit is due…
The vi code is ported from the BusyBox source code.
The compiler code is a remix of the amacc compiler parser generator and the c4 virtual machine. Many important amacc enhancements such as floating point, array, struct and type checking support were taken fom the Squint project.
What’s new in pshell
About the compiler, briefly…
Data types: integer, float, char and pointer.
Aggregate types: array, struct and union.
Flow control: for, while, if then else, break, continue and goto.
Memory, math and SDK functions. (list of implemented functions)

Screen share ANYTHING to this matrix! (Pi Pico)
https://www.youtube.com/watch?v=yzRHAdS9FLY
My first take on MicroPython and the new Raspberry Pi Pico W. Had some struggle wit the lacking ram but at the end a simple screen share worked which allows you to project anything shown on your PC screen to a nice LED Matrix display wirelessly. The case with back projection screen is printed in one Piece. It’s a super simple project to make on a weekend. I have better Websocket versions coming so subscribe to not miss that.

In this video we will be having a closer look at the first microcontroller board from Raspberry Pi, the Raspberry Pi Pico. The board is 1.5 years old but back then I was convinced that it was overrated. But things changed and nowadays I think it is a good Arduino alternative. So let me show you how to use the board and what exactly happened that made me change my mind. Let’s get started!

David Bell is one of our interns, and is equipped with one of the office Peltier coolers. He decided last week to indulge in some experimentation to find out how much he could overclock our RP2040 chip.

https://www.raspberrypi.com/news/dont-try-this-at-home-overclocking-rp2040-to-1ghz/
It turns out that with some very special treatment, RP2040 can be overclocked to be shockingly fast. And overclocking it as David describes here will also stop it working altogether – but it’s all about the journey, right? Here’s David to tell you more.

Bit-Banged Ethernet On The Raspberry Pi Pico
https://hackaday.com/2022/08/26/bit-banged-ethernet-on-the-raspberry-pi-pico/
Whilst the Raspberry Pi RP2040 is quite a capable little chip, on the whole it’s nothing really special compared to the big brand offerings. But, the PIO peripheral is a bit special, and its inclusion was clearly a masterstroke of foresight, because it has bestowed the platform all kinds of capabilities that would be really hard to do any other way, especially for the price.
Our focus this time is on Ethernet, utilizing the PIO as a simple serialiser to push out a pre-formatted bitstream. [kingyo] so far has managed to implement the Pico-10BASE-T providing the bare minimum of UDP transmission (GitHub project) using only a handful of resistors as a proof of concept. For a safer implementation it is more usual to couple such a thing magnetically, and [kingyo] does show construction of a rudimentary pulse transformer, although off the shelf parts are obviously available for this. For the sake of completeness, it is also possible to capacitively couple Ethernet hardware (checkout this Micrel app note for starters) but it isn’t done all that much in practice.
Pico-10BASE-T
https://github.com/kingyoPiyo/Pico-10BASE-T

Note:
DO NOT CONNECT to PoE equipment!!
Currently transmission only (UDP is available)
Receiving process will be implemented in the future…
It is advisable to insert a pulse transformer for safety.

An Elegant Ethernet Library For Your Next RP2040 Project
https://hackaday.com/2022/08/27/an-elegant-ethernet-library-for-your-next-rp2040-project/
A few days ago we covered a project that brought Ethernet connectivity to the Raspberry Pi Pico using little more than some twisted pair and a RJ-45 connector. It was a neat trick, but not exactly ready for widespread adoption. Looking to improve on things a bit, [tvlad1234] has taken that project’s code and rewritten it into a friendly library you can use with any RP2040 board.

Share Screen To RGB Panel With Pi Pico W
https://hackaday.com/2022/08/28/share-screen-to-rgb-panel-with-pi-pico-w/
RGB LEDs are great for adding a bit of color to your life, and it’s even more satisfying to use a matrix of them as a graphic display. [bitluni] built an RGB LED display with Pi Pico to which you can share a pixelated version of your PC’s screen.
[bitluni] wanted to gain some experience with MicroPython on the Raspbery Pi Pico W, and had previously used WebSockets to transmit display data over WiFi. Unfortunately, the available MicroPython WebSockets implementation didn’t leave enough RAM for the rest of the code. Instead, he set up a simple HTTP server on the Pico that receives the pixel data as a POST request. This makes for a slow refresh rate but still looks great, especially with the 3D printed rear-projection frame.

[feralAI] and fellow GitHub contributors present for your viewing pleasure GP2040: an open source game pad firmware for RP2040-based hardware. The dual-core RP2040 is a good platform to use for gaming inputs, as there is plenty of CPU grunt to get sub-1 ms USB polling time, regardless of any other tasks the controller may be performing. Currently the firmware supports PC, Android, RPi, Nintendo Switch, PS3, PS4 (legacy mode), and the sweet MiSTer FPGA-based retro-gaming platform.
