PICNIC - PIC with Ethernet Controller

PICNIC is a project to add 10BaseT Ethernet controller to PIC17F877, and it can run as an network-enable device.
This project is based on tristate's PICNIC product. And I just change the temperature sensor's circuits to improve the precision on A/D convert and add another Temp-Sensor channel.

Features:

• Build in Realtek RTL8019AS Ethernet Controller IC (10BaseT)
• MAC address are configurable via rewrite the 93C46 eeprom.
• Build in RS232 serial interface can connect to any host, and Transfer/Receive via network by UDP protocol
• LCD interface, can show IP address and any message by UDP protocol
• Drive the output port to I/O or H/L, could be used as an extension.
• Build in WWW server to show and change the configuration.
