PICDEM.net™ Internet/Ethernet Demonstration Board Summary The PICDEM.net™ demonstration board is an Internet/Ethernet demonstration board using the PIC18F452 microcontroller and TCP/IP firmware. The board supports any 40-pin DIP device that conforms to the standard pin-out used by the PIC16F877 or PIC18F452. The board now uses the free Microchip TCP/IP Stack, which is available in Application Note AN833 (DS00833). Please refer to this document for code samples. The Microchip TCP/IP Stack is a suite of programs that can either provide services to standard TCP/IP-based applications (HTTP Server, Mail Client, etc.) or be used in a custom TCP/IP-based application. Potential users do not need to know all of the intricacies of the TCP/IP specifications to use it, and those interested only in the accompanying HTTP Server application need not have specific knowledge of TCP/IP. The TCP/IP stack is implemented in a modular fashion, with all of its services creating highly abstracted layers, each layer accessing services from one or more layers directly below it. The stack is written in the ‘C’ programming language, intended for both Microchip C18 and HI-TECH PICC 18 compilers, and is designed to run on Microchip's PIC18 family of microcontrollers only. Although, this particular implementation is specifically targeted to run on Microchip’s PICDEM.net Internet/ Ethernet demo board, it can be easily retargeted to any hardware equipped with a PIC18 microcontroller. The PICDEM.net supports Ethernet and RS-232 interfaces. With a standard web browser such as Microsoft®Explorer, HTML web pages generated by the PICmicro®MCU can be viewed. The initial board configuration is performed via the RS-232 port using a standard terminal program to configure the IP, Ethernet, etc., addresses for the board. The demo board is also equipped with a 6-pin modular connector to interface directly with the MPLAB® ICD 2 In-Circuit Debugger. With MPLAB ICD 2, the developer can now modify or reprogram the onboard Flash-based PICmicro device to meet the specific needs. A generous breadboarding area is also available to add special circuits for experimentation. The area is large enough to add an embedded modem to provide for dial-up capability. Several status indicators and user interface devices are provided, including a 16 x 2 LCD indicator and LEDs.
