Raspberry Pi Pico W first power up and install MicroPython firmware
This video show first power up
Raspberry Pi Pico W
and install MicroPython firmware on it.
To download
MicroPython firmware (in UF2 form) for Raspberry Pi Pico W, visit:
https://www.raspberrypi.com/documentation/microcontrollers/micropython.html#drag-and-drop-micropython
or from MicroPython page here: https://micropython.org/download/rp2-pico-w/
New Pico W come with empty Flash memory, and boot up in BOOTSEL mode. So I
can drag-and-drop the MicroPython UF2 file to Pico W directly.
If
your Pico W is not in BOOTSEL mode, you can hold down the BOOTSEL button
when you plug in your Pico, it will appear as a drive onto which you can drag
a new UF2 file.
or, you can restore factory flash memory with
flash_nuke.uf2 HERE.
Exercise of MicroPython on Raspberry Pi Pico W:
~ connect to WiFi network and synchronize to NTP Time Server
