Webserver example that came with TinyUSB slightly modified to run on a Raspberry Pi Pico. Lets the Pico pretend to be a USB Ethernet device. Runs a webinterface at http://192.168.7.1/
On Debian:
sudo apt install git build-essential cmake gcc-arm-none-eabi
Your Linux distribution does need to provide a recent CMake (3.13+). If not, compile CMake from source first.
git clone --depth 1 https://github.com/maxnet/pico-webserver
cd pico-webserver
git submodule update --init --depth 1
mkdir -p build
cd build
cmake ..
make
Copy the resulting pico_webserver.uf2 file to the Pico mass storage device manually. Webserver will be available at http://192.168.7.1/
Content it is serving is in /fs If you change any files there, run ./regen-fsdata.sh
By default it shows a webpage that led you toggle the Pico's led, and allows you to switch to BOOTSEL mode.
