Raspberry Pi Pico Hello World on Windows

raspberry pi pico  · 

The documentation for the Raspberry Pi Pico assumes your Pico is plugged into another Raspberry Pi.

Here’s how to run the Hello World sample on Windows.

The first four steps are the same so this is ripped from the original C documentation:

  1. Download the ‘Hello World’ UF2.
  2. Push and hold the BOOTSEL button and plug your Pico into the USB port of your > Raspberry Pi or other computer.
  3. It will mount as a Mass Storage Device called RPI-RP2.
  4. Drag and drop the ‘Hello World’ UF2 binary onto the RPI-RP2 volume. Pico will reboot

So now you’ve done that, the first thing we need to find out is which communication port the Pico is using.

  1. Open the command prompt and run:
mode

You will see output similar to this:

Status for device COM3:
-----------------------
    Baud:            115200
    Parity:          None
    Data Bits:       8
    Stop Bits:       1
    Timeout:         OFF
    XON/XOFF:        OFF
    CTS handshaking: OFF
    DSR handshaking: OFF
    DSR sensitivity: OFF
    DTR circuit:     OFF
    RTS circuit:     ON


Status for device CON:
----------------------
    Lines:          9001
    Columns:        120
    Keyboard rate:  31
    Keyboard delay: 1
    Code page:      850

We can see that the Pico is COM3 because the baud rate is set to 115200.

  1. Now, open PuTTY

  2. Set the Connection Type to Serial

  3. Set the Serial Line to the communication port from the previous step, which is COM3 for me

  4. Change the Speed to 115200

  5. Click Open

If you see "Hello World" being printed to the console then it worked :)
