Introduction

The PROTON-NET development system is an Internet/Ethernet prototyping board using the PIC® 16F877 microcontroller and Networking Firmware. The firmware was developed for the Crownhill Proton-Net board by Jeremy Bentham of Iosoft Ltd. based on the principles demonstrated in his book TCP/IP Lean: Web Servers for Embedded Systems (ISBN: 1-929629-11-7). Conveniently Jeremy lives just a few miles from Crownhill's offices, so Iosoft Ltd. have teamed up with Crownhill Associates to bring you:

• A low-cost PIC® microcontroller network prototyping board
• Proton Plus PIC® BASIC compatible source code, with User Datagram (UDP) functionality
• A PC interface, using Visual Basic

The PROTON-NET board supports any 40-pin DIP device that conforms to the standard pin out used by the PIC® 16F877 or PIC® 18C452 and affords low-cost entry into TCP/IP networking on the PIC® microcontroller using the BASIC language, demonstrating data transfer between PCs, target boards, and the Internet, all using the Crownhill Proton Plus BASIC language. The Proton-Net board is also equipped with a 6-pin modular connector to interface directly with the Microchip In-Circuit Debugger (ICD).

Hardware



Proton-Net development board

The Crownhill Associates Proton-Net board provides an ideal development platform for PIC® microcontroller network experimentation. It includes:

• Full compatibility with existing PIC® microcontroller Ethernet designs
• PIC® 16F877 or PIC® 18F452 microcontroller with in-circuit programming
• ICD interface
• RTL8019AS Ethernet controller
• 32 Kbyte storage for Web pages
• 2x16 LCD display
• RS232 Interface
• On Board AtoD (test source)
• Regulated power supply
• Generous prototyping area (including Solderless development)
• Full access to all PIC® microcontroller pins
• Solder or solderless prototyping options
• Straight through and crossover CAT5 cables
• Power supply (UK Specification)
• Documentation including get you started section
• FULLY Commented source code, with worked examples, to get you up and running in less than an hour

The Proton-Net is fully compatible with all the existing PIC® microcontroller Ethernet software in the 2nd edition of 'TCP/IP Lean', providing a 'C' language upgrade path to handle more complex networking requirements.

PIC® microcontroller Software
