Web server TCP/IP Development Board PIC-WEB is a compact board which is supported by Microchip's open-source TCP/IP stack AN833. The board is designed with a 64-pin PIC18F67J60 microcontroller which has a built-in Ethernet controller, supporting SLIP, ARP, IP, ICMP, TCP, UDP, HTTP, DHCP, and FTP. The Microchip stack is very modular and flexible so you can enable or disable modules, and it supports dynamic web pages which give you the possibility to control all PIC resources remotely via FTP, HTTP, UDP, TCP, etc.
With this board, you can implement web and FTP servers, send e-mail and almost everything that the big servers do. The on-board 1Mbit serial Flash is available for data storage. This board is designed to have web page of no more than 128 kB. If you want a lot of images in your application, you can host them on another server visible on the network where you have the PIC-WEB connected. The potential of the board is to generate fluid communication between some specific sensors or actuators across a TCP/IP net including controls.
The Microchip stack is an open-source library which you can modify and compile at any time. You probably will need to modify it to your own needs. The board comes with an implemented web server and a web page that lets you control some of the features of the board. The best thing is that you don't have to be a PIC programmer or know C; you can make your project in HTML, Javascript, or Ajax and have all PIC resources as dynamic variables so you can toggle GPIOs and read ADC values etc. in your HTML code. To add new variables you can add them in HTTPPrint.h also which is part of the stack, then rebuild and upload to new code to the PIC-WEB.
The board has two headers for connecting external devices, one of which is a standard pinout used by dozens of pre-existing devices; see below.

With IP set to 192.168.0.30, you can configure the PIC-WEB TCP/IP via RS232 (you may need to disable DHCP if the page doesn't open on the first try). See the User Manual for details.
Add-on UEXT Modules Available This board has a universal extension connector, UEXT, which allows you to add a peripheral module easily. The UEXT can provide I2C, RS232, SPI and power to the external device. Please see the UEXT Boards Category PIC Web Board Resources Note: This board does not ship with any documentation or software. Download all necessary documentation & software from links above.
Remember that if you select the RJ12 ICSP adapter from the options below, you'll also need the 1.25mm 6-pin SIP adapter shown right above it.
