Testing Raspberry Pi Pico W. Blinking LED and enabling serial USB communication.
First, RP2040 has to be flashed with simple blinking LED plus sending "Hello, World!" by serial communication.
Setting up debugger helps to understand what's inside RP2040. Allows to flash it without BOOTSEL button.
Test with GitHub Actions were done. Now releases are done automatically as pushes to branch "master" keep coming.
