The Dangerous Prototypes web platform is a tiny server designed for networked hacks where a full PC is inconvenient. There’s lots of interesting projects that bridge the internet to microcontrollers, but most of them have a PC in the middle to handle network stuff. This business card-sized internet appliance can connect to web services, control physical objects from a browser interface, or email sensor status reports; no PC intermediary required!

Overview

Introduction

My web platform has just arrived. Now what?

• Web platform quick start

Learn about the web platform design.

• Web platform hardware design
• Web platform firmware

The original web platform blog post has been moved here and updated. You can still find the original article and comments here.

Downloads

• Web Platform package v1c
• Web Platform source r1052 v1c
• Browse the Web Platform SVN

Hardware

See the example HardwareProfile.h file for a complete list of peripheral connections.

• Web Platform schematic and partlist
• IO Header pinouts
• Hardware errata

Hacks

• USB power supply for v1c hardware (original)
• Reset PIC for bootloader with FTDI chip (original)

Firmware

• Firmware upgrade procedure
• Hardware and firmware downloads
• Latest hardware and source are in SVN

Introduction

• Introduction to dsPIC33 programming (original)

Microchip TCP/IP stack

The Microchip TCP/IP stack is freely available, but we can't distribute the code. There is now an archive of older versions, Microchip Application Libraries v2010-02-09 (TCPIP stack v5.20b) should work.

• SD card web server demo (original)
• Twitter controlled Christmas tree (original)
• Enable extra web server features, TCP/IP stack overview
• Telnet server hacking
• Adding extra SPI devices

uIP TCP/IP stack

uIP is an open source TCP/IP stack that currently has fewer features than the Microchip stack.

• Web platform: uIP TCP/IP stack port

FreeRTOS

• FreeRTOS on the web platform
• FreeRTOS port in SVN
• Alternate FreeRTOS port in SVN

Contiki

• Contiki OS on the web platform

Other demos

• Python on the web platform source code
• Playing SID tunes on the web platform, source code, HEX file, Tunes, demonstration video

Bootloader

The web platform uses the ds30 Loader GPL licensed bootloader.

• ds30 Loader for web platform
• Bootloader hacking by the ds30 Loader author

• Bootloader: GPL (from ds30 Loader project)
• Firmware: CC-0 (see source, excluding Microchip TCP/IP stack)
• The web platform is a development board and we believe that you should be able to use it (or parts of it) however you want. We release our parts of the PCB and schematic into the public domain (or Creative Commons 0, your choice). All recent hardware files use custom parts, but the first version of the web platform used a FTDI chip and USB jack from SparkFun's CC-BY-SA part library and were CC-BY-SA.
