Ethernet controller

PIC NIC Ethernet controller

PICNIC is a project designed to add a 10BaseT Ethernet controller to the PIC17F877, enabling it to operate as a network-enabled device. The project is based on Tristate's PICNIC product. I just modified the temperature sensor circuitry to improve A/D conversion accuracy and added another temperature sensor channel.

characteristic:

* Built-in Realtek RTL8019AS Ethernet controller IC (10BaseT)

* The MAC address can be configured by rewriting the 93C46 EEPROM.

* Built-in RS232 serial interface allows connection to any host and data transmission/reception over a network via UDP protocol.

* LCD interface, which can display IP address and any messages via UDP protocol.

* Drive the output port to I/O or H/L for expansion.

* Built-in WWW server for displaying and changing configurations.
