INTRODUCTION:

This board allow you to develop easy Ethernet connectivity application. It have everything you normally would need for such activity: power relays which you can command through web interface. LCD display which will display messages you fill in web forms, analogue inputs for connection to sensors, digital optoisolated inputs, trimmer potentiometer, temperature sensor, Ethernet connector. With this board you can easy automate your home and then control and monitor it from any point in the world via Internet. The extension connector is available so you can connect your cusom made hardware hassle free. The PIC18F97J60 have 128KB Flash programming memory and there is external 1Mbit (128KB) flash memory for data storage. The on board DC/DC converter make this board to be very tolerant to the external power supply which could be in 9-25V DC or 7-18V AC range, the bridge rectifire on the input allow AC and DC adapters to be used and makes power supply polarity problems go away.

DOCUMENTS:

• PIC-MAXI-WEB.pdf - User manual
• Understanding PIC WEB boards and Microchip TCP-IP stack tutorial
• Microchip TCP/IP AN833 - please read carefully, the TCP/IP stack is described
• PIC-MAXI-WEB software setup provided by customer of ours Tom Nguyen

HARDWARE:

• PIC-MAXI-WEB REV.A schematic
• PIC ICSP connector

• Microchip-5.31 stack patch free Microchip's TCP-IP stack tuned for PIC-MAXI-WEB with DHCP disabled and IP set to 192.168.0.30, all boards are shipped with pre-loaded TCP-IP stack
• There is a known issue with C18 V3.37.01 & TCIP/IP V5.31 (or TCIP/IP V5.00). The fastest workaround is to use the previous C18 (v3.34) until the next C18 version is released. Another work around is to use this p18f67j60.h instead the one provided by the newer compilers
