Test Using Read-Evaluate-Print-Loop (REPL)įor this step, you will only need CoolTerm and your Pico W plugged into your computer. ( For which the computer might complain, however, its not a big deal.) 3. It will take several seconds to copy the 1MB+ size file on to the Pico and the board will restart, automatically ejecting itself from the computer. uf2 file you downloaded from the MicroPython site and drop it on the USB drive RPI-RP2. Did you follow the 3-step sequence above exactly? The timing is critical.Are the connections to the button diagonally opposite? ( as compared to straight across).Is there a wire from pin 30 RUN to the button?.Is there a wire from the GND rail on the breadboard to the button?.Is there a wire from GND on the Pico to the GND rail on the breadboard?.If the board doesn’t show up, check your connections to the Reset button. Your board will show up on your computer as a USB drive labeled RPI-RP2. Press and hold the BOOTSEL button on the Pico W.With a USB cable plugged between your PICO and your computer: Having a reset button enables you to easily put the PICO W into USB mode. If you want the code discussed in this entry, you may download it here. It can be found under Firmware, on the link above ( …Pico W download). To use MicroPython on the Pico, you must download the UF2 file which contains MicroPython for the Pico W. The blinkenleds are a good example below. Note: The value of creating GND rails, is that it makes it easy to ground other components as you extend the functionality of your Pico with hardware. Connect a wire ( blue wire in image) into the breadboard row diagonally opposite the GND connection to pin 30 RUN on the Pico.Connect a wire ( gray wire in image) into one end of the push button to GND.Plug a push button spanning the center channel into your bread board at the end of the Pico.(I use pin 3 on one side and pin 38, on the other side). Create GND rails on your breadboard by connecting wires ( gray wires in image) from a GND pin on the Pico to the blue “-” rail on the breadboard.Install header pins or purchase your Pico W with header pins.Install a RESET buttonįor ease of use, I recommend the following steps: Once Python is installed use pip to install:Īction, perform the following two steps: 3.1. # install Homebrew per instructions on site brew.sh # install git for version control brew install gitĢ.3. Homebrew - Use the homebrew installer for macOS to install git.

For command line interface ( CLI), use Apple’s Terminal program.

Git for Windows - This will provide both the Command Line Interface ( CLI) for Windows ( git-bash) and version control, git.

Python 3 - Use the official installer for both Windows and macOS.

CoolTerm - multi-platform serial monitor ONLY DOWNLOAD FROM THIS SITE: For more information, go here.

Sublime Text - multi-platform code editor, will be the code editor used in this series.

Multi-platform, install the appropriate version Install the following tools, as all of my examples will use them.Īction: Install all items from steps 1-3 appropriate to your computer’s operating system.Ģ.1. In addition to the books above, the following links will be important.Īction: Bookmark these links them and have them available in your browser. Get Started with MicroPython on Raspberry Pi Pico.These two books are free and are extremely valuable.Īction: Download them and have them available on your computer. I highly recommend having documentation to help you on this journey. The cost ( $6) of the Pico W, with it’s computing power and wireless capability coupled with the ease of development of Micropython, makes this combination compelling. While I’ve experimented with multiple boards using the language, ESP32, FIDI, and the Adafruit Feather RP2040, this entry begins a set of entries on using Micropython as a development language with the Pi Pico W as the development microcontroller. I already have quite a few entries on Micropython. Where I demonstrate how to begin to program the RP2040 (Pi Pico and Pi Pico W) using Micropython.
