uLisp now supports Wi-Fi on the Raspberry Pi Pico W


If you’re looking for a low-cost microcontroller board with Wi-Fi the obvious choice used to be the ESP32, but now it has a challenger in the shape of the Raspberry Pi Pico W:

It’s pin-compatible with the original Raspberry Pi Pico, but adds an Infineon CYW43439 to provide 802.11n single-band 2.4 GHz Wi-Fi with WPA3 and a Soft Access Point supporting up to 4 clients.

The latest version of ARM uLisp, Version 4.2, adds support for the Wi-Fi features, which are identical to the same features on the ESP32. For details see Wi-Fi extensions, and for examples see Wi-Fi examples.
