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:
It’s been a big week. We launched something tiny, something new – Raspberry Pi Pico, just for you.
Read all about it, plus everything else that went down at Raspberry Pi in the last few days, in Raspberry Pi Weekly.

Best RP2040 Boards 2022
By Les Pounder

Get the best RP2040 board for your projects.
https://www.tomshardware.com/best-picks/best-rp2040-boards
While Raspberry Pi boards have been around since 2012, they have been powered by Broadcom SoCs. But in January 2021 we saw the first Raspberry Pi silicon, the RP2040 arrive and in a short space of time it has become a major SoC in the maker community. With two Arm Cortex M0+ cores running at 133 MHz, 264KB of RAM and up to 16MB of Flash, these chips open up a new range of microcontrollers that compete more closely with traditional Arduino boards than a Raspberry Pi 4.
While Raspberry Pi has its own RP2040-powered board in the Raspberry Pi Pico, there are now more than sixty, third-party solutions that offer improvements which range from smaller sizes to built-in Wi-Fi, more storage or a lot of additional outputs. There are even RP2040-powered keypads and RP2040 breakouts designed to be embedded into your next project. All of these boards share the same $1 RP2040 chip, but offer much more than the stock model.
With Raspberry Pi still being hard to come by we’ve compiled the best RP2040 boards to get your projects up and running. These boards can be used for everything from general learning to building Wi-Fi connected robots to implementing basic A.I.

Bit-Banging Bidirectional Ethernet On A Pi Pico
https://hackaday.com/2022/12/03/bit-banging-bidirectional-ethernet-on-a-pi-pico/
These days, even really cheap microcontroller boards have options that will give you Ethernet or WiFi access. But what if you have a Raspberry Pi Pico board and you really want to MacGyver yourself a network connection? You could do worse than check out this project by [holysnippet] that gives you a bit-banged bidirectional Ethernet port using only scrap passive components and software.
This project is similar to one we shared back in August by [kingyo], but differs in that what [holysnippet] has achieved is a fully-functional (albeit only around 7 Mbps) Ethernet port, rather than a simple UDP transmit device.

A PI PICO OSCILLOSCOPE
https://hackaday.com/2022/11/06/a-pi-pico-oscilloscope/
Now [jgpeiro] has made one which is light years ahead of the toy kits, using a Raspberry Pi Pico, a 100 MHz ADC, and an effort to design a better input circuit.
At its simplest this could be a straightforward op-amp and ADC circuit feeding the Pico, but instead it has multiple stages carefully designed to offer the full bandwidth, and with gain, offset, and trigger settings being set by a series of DAC chips under software control. This and the decent bandwidth make this a much more viable oscilloscope, and one we’d like to see further developed.

This project is a dual channel oscilloscope based on RP2040. It has a 100MSps ADC, a 480*320 IPS TFT and a dual channel 100MHz BW front-end.
The software is based on MicroPython and LVGL and DMA and PIO are used to achive the highest possible througput.

This project is similar to one we shared back in August by [kingyo], but differs in that what [holysnippet] has achieved is a fully-functional (albeit only around 7 Mbps) Ethernet port, rather than a simple UDP transmit device. The Ethernet connection itself is handled by the lwip stack. Connection to the RJ45 socket can be made from any of the Pi Pico pins, provided TX_NEG is followed directly by TX_POS, but the really hacky part is in the hardware.

PINA
Pico-w energy meter with INA228
https://hackaday.io/project/188702-pina
An ultra-precise energy meter based on Pico-w, INA228 energy monitor and sigrok analysis software
The aim of this project is to create an ultra-precise energy meter based on INA228 TI’s energy meter device. INA228 is a 20-bit energy meter device, with I2C host interface capable of measuring voltage/current/energy at sampling rates up to 20Hz. The device is connected to a Raspberry Pico W host acquiring the data from the I2C interface and communicating with the host through the WiFi interface using a TCP protocol. In addition, the Pico-w module will be able to store IO level on DUT (Device Under Test) and transmit the data to the host application.
On the host side, a basic driver is implemented for libsigrok for communicating with the Pico W firmware and propagating the data to sigrok suite.
Pico-w is running a uPython firmware communicating with INA devices – acquiring the measurement data – gathering IO data and sending the data to the TCP client – connected to the acquisition port (default port is 5555).

USB Host On RP2040 – With PIO
https://hackaday.com/2022/12/28/usb-host-on-rp2040-with-pio/
Folks from [Adafruit] are showing off a neat hack – USB host on RP2040, using the now-famous PIO peripheral. [Adafruit] builds a lot of RP2040 boards, and naturally, you gotta test them before you ship them to customers. They’ve been using very specific Teensies for that, and at some point, those became unobtainium. Based on the work of [sekigon-gonnoc] and with help of [Thach], they’ve made their TinyUSB library support bitbanging of USB over PIO, and successfully ported their test jig firmware to it!
The base Pico-PIO-USB repo by [sekigon-gonnoc] shows a pretty impressive state of affairs – with low-speed and full-speed USB host and full-speed USB device modes supported, and quite a few examples to get you started. [Adafruit]’s work integrates this code into their TinyUSB stack, specifically focusing on MST (mass storage) features – as this is what you need to program a RP2040. Of course, they also provide a mass storage example to boot!
