Browsing projects based on the Raspberry Pi Pico I have found one which uses the TinyUSB and IwIP projects to create simple web client or server available via emulated USB ethernet. This example is documented and available here: https://github.com/maxnet/pico-webserver. I have decided to modify little this example to host basic HTML games on the Raspberry Pi Pico. I have found nice examples of basic HTML games here: https://gist.github.com/straker/. I have create simple index.html page with links to few HTML games. Below there is source code of this page:
<!DOCTYPE html>
<html>
<head>
<style>
body {
margin: 0;
font-family: Arial, Helvetica, sans-serif;
}
.bg-image {
background-image: url("backgorund.jpg");
height: 1024px;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
position: relative;
}
.bg-text {
text-align: center;
;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
color: white;
}
</style>
</head>
<body>
<div>
<div>
<h1 style="font-size:50px">Basic HTML games</h1>
<form>
<button type="submit" formaction="breakout.html">Breakout</button>
<button type="submit" formaction="frogger.html">Frogger</button>
<button type="submit" formaction="pong.html">Pong</button>
<button type="submit" formaction="snake.html">Snake</button>
<button type="submit" formaction="sokoban.html">Sokoban</button>
<button type="submit" formaction="tetris.html">Tetris</button>
</form>
</div>
</div>
</body>
</html>After that is required to regenerate file system data by calling script called: regen-fsdata.sh. I have modified also file webserver.c and removed unused CGI handles. For this example we need only initialization of tinyusb, lwip, dhcpd and httpd. At the end I have generated image in format uf2 and copied it to Raspberry Pi Pico. After reboot in system is present a ethernet interface. When we type in browser following address: http://192.168.7.1/ we can see a main page hosted on Pico. Below there is short video presentation:
