How To Install Windows 10 On A Raspberry PiIn this video we will be taking a look at how to install actual windows 10 onto the raspberry pi.Products Used:htt. Install Windows 10 ARM on a Raspberry Pi!: The Raspberry Pi is a great board for doing many things. There are many Instructables on things like IoT, Home automation, etc. In this instructable, I will show you how you can run windows on arm desktop on your Raspberry PI 3B!

This article answers the question: How do I use the Raspberry Pi Pico with MicroPython on Windows? We also show how to install the right driver for “Board CDC” (which the Pico will show up as once MicroPython is installed) on Windows 8.1.

Finally, we’ll show how to connect to the Pico using PuTTY, and a more comfortable option using Thonny (which is a Python IDE, integrating with the Pico!)

Introduction: What is Pico, what is MicroPython?

The Raspberry Pi Pico is a new microcontroller board from Raspberry Pi, sporting the in-house developed RP2040 microcontroller chip.

Raspberry Pi have designed lots of cool features into the RP2040 (my favorite is PIO – programmable IO, where you can emulate lots of hardware interfaces which require precise timing, etc. – I’ll go into it in another article in the future), and Pico is a really nice reference platform the RP2040 is implemented on.

How is a Raspberry Pi Pico different from a Raspberry Pi Zero W?

The difference between Microcontroller (Pico) and Single-Board-Computer (let’s say Pi Zero W) is roughly this: you program the Pico directly (e.g. in C), without an operating system, whereas the Pi Zero W will usually run Linux. This has advantages, like real-time, but also disadvantages – you need to know more about the hardware you are using, and need to implement a lot of functionality which you would take for granted on a modern operating system (e.g. file access). The Pico has less resources compared to the Pi Zero W (e.g. significantly less RAM, no VideoCore GPU, …) – but it draws less power, and has additional features, like the aforementioned PIO, and analog inputs (ADC).

The Pico is a good choice for projects which do not necessarily require network connectivity, HDMI output, camera input and processing. In other words, if you want to interface with hardware, have a long battery life, etc – then the Pico is for you.

What software does already exist for the Pico?

The Pico can be flashed using different software, which is provided in UF2 files (see Pico getting started guide). Raspberry Pi provides several UF2 files to get you started:

MicroPython (which will be the focus of this article)
Blink an LED (Blink UF2)
Hello world (will say “Hello world” if you connect through a terminal)
Picoprobe (use one Pico to debug another Pico)
Reset flash memory (will set the Flash memory to empty)

There is lots more of examples to be found here (C code).

Note: I’m linking to the newest UF2 files as of 30.01.2021 – specifically MicroPython might be updated, so be sure to check on the Raspberry Pi Pico getting started page.

MicroPython

If the prospect of going full-in and programming in C seems a little bit daunting to you, you can get started in MicroPython. In this case, some software is pre-installed to the Raspberry Pi Pico (the MicroPython UF2 file), which will run a small Python interpreter.

It’s called MicroPython because it doesn’t support the full Python 3 standard library. MicroPython is intended for constrained environments, like the Pico. The Pico has a total of 2 MB RAM – this will not fit everything Python 3 brings along with it. Check this Github page for differences of CPython to MicroPython. Also, here’s the official MicroPython homepage, and the official MicroPython documentation.

What will you get with the MicroPython UF2?

Once MicroPython is installed on the Pico, you’ll be able to connect to the Pico using the serial console (we will show how in this article), and start writing Python code on the Pico.

Installing MicroPython on the Pico

Remove power from the Pico
Press the BOOTSEL button and keep it pressed
plug in the Pico to your PC using a microUSB to USB cable
now you can release the BOOTSEL button

The Pico should be visible in your filesystem now, as RPI-RP2:

(Sidenote: I wonder what RPI-RP1 was?)

The Pico emulates a FAT32 flash drive, which has two files in it: INDEX.HTM and INFO_UF2.TXT.

In fact, Windows Drive Manager shows Pico to be a 128 MB FAT flash drive.

Don’t make the mistake of trying to store any files on the Picothis way: they will be silently dropped. Even if it looks like they’re written, that’s just Windows caching the operations – your files will be gone! Did I mention already that the Pico actually has only 2MB Flash? It’s shamelessly lying about the 128MB here (the RP2040 is supposed to support up to 16MB flash by the way, AFAIK).

Sidenote: This reminds me a bit of my trip to India, where I bought thumb drives with 128 GB capacity – which would write your data to Nirvana. When I tried to return the drive and get my money back, the vendor was gone … the adventures to be had 🙂

However, if you copy the right kind of file – the UF2 file – to this drive, it will be recognized and written.

You can drag & drop it from your browser, after having downloaded it, or copy & paste it. Once it’s completed copying, the Pico will reboot automatically, and you won’t see a flash drive anymore.

The Pico now (after the reboot) runs MicroPython, which provides a serial port (COM-port) via USB. (In technical terms, this is USB device class 02 = Communications and CDC Control and USB device SubClass 02).

Connecting to the Pico, Windows 10

Windows 10 makes it easy for us to connect to the Pico, as the necessary COM-Port driver (usbser.inf) will be automatically installed and activated for you.

To check which COM Port it’s on, open your device manager:

Here, you’ll be able to see the new USB Serial Device, with the COM port number (which you’ll need in a second to connect), under Ports (COM & LPT).

To double-check that this is indeed the Pico, running MicroPython, you can do the following:

Click on View, and select Devices by Container:

Here you’ll see an entry “Board in FS mode”, with the two nodes “USB Composite Device” and “USB Serial Device (COM3)”. The COM3 is important, you will need to use it for PuTTY (see below).

We can investigate the devices further by right-clicking on them, and selecting the appropriate properties entry from the context menu. The properties for Board in FS mode are empty:

The USB Composite Device shows “Board in FS mode” as it’s Bus reported device description:

Note: this is the Pico running MicroPython. When you reflash it with different software, it will show different results here!

The USB serial device itself will show some interesting properties:

If you know what you are looking for, the Hardware IDs (VID = vendor id, and PID = product id) are useful:

VID_2E8A -> the vendor id is 2E8A (in hex) or 11914 (in decimal), which is Raspberry Pi

PID_0005 -> the product id is 5, which the board will show when running MicroPython (the default product id is 3)

Sidenote: Chrome Browser debug log

This information can also be obtained using the Chrome browser.

will allow you to see the currently attached Devices

Back to Windows 10:

As you see in the screenshot above, Windows 10 automatically installed usbser (USB Serial Driver) for you – so you can get started with the Pico immediately.

PuTTY

PuTTY is a telnet / SSH client. You will use it to connect to the Pico, and talk to MicroPython’s REPL. Download PuTTY here. (You can go with the 64-bit MSI Windows Installer for most Windows 10 installations)
