The Netzer Project

This project realizes an Ethernet interface on a PIC-based platform.

As a gateway module it enables communication between standard TCP/IP sockets and serial busses like I2C, SPI and UART. Also up to 13 GPIO pins can be accessed (written to or read from).

Here is an overview of features:

  • Ethernet device with tiny TCP/IP stack
  • Based on a low-cost 8-bit PIC microcontroller (PIC18F67J60) from Microchip
  • Bootloader integrated for easy firmware updates with TFTP
  • Integrated webserver for configuration with dynamic websites
  • User based webserver authorization
  • Multicast DNS functionality for easy device and service discovery with Bonjour
  • Power-over-Ethernet: Prepared for power supply via the ethernet connection (PoE - 802.3af)
  • Extensive settings via the webinterface
  • Unlimited parallel usage of modules
  • Usage of 2.54 mm pinheaders enables simple integration in custom circuits
  • Interfacing SPI, I2C and UART
  • Two ADC channel for sensing
  • Two PWM and Impulse channel for control
