Using the Arduino Ethernet shield with AMICUS18 (Part 1~4)


Using the Arduino Ethernet shield with AMICUS18 (Part 1~4)

by HenrikOlsson

He had very much activity on the forum of, he posted it in this forum how to use the Arduino Ethernet Shield with AMICUS18 Open source hardware board based on PIC MCU.
The pisbasic made the 4 aticles with his posts.

AMICUS18 board

This board is based on PIC MCU and is compatible with Arduino Board. It is developed with Crownhill’s Proton BASIC.

Part 1

In Part One, He explains how to connect the Ethernet Shield with AMICU18 board.

  • Because AMICUS18 board has no ICSP HEADER, Ethernet shield is modified for sharing the SD card on the Ethernet shield.

Part 2

In Part Two, He explains how to define the interface for controlling UART, SPI interface, and W5100 memory map.

Part 3

In Part Three,
He made the code of WIZnet W5100 interace routines, and he configues W5100’s network information as mac address, local ip, gateway ip, and subnet mask by this routines.And he tried to test with ping to W5100.

  • Ping Test

Part 4

In Part Four, He made the transmit & receive routine with W5100,tried to receive a HTTP request message from a Web-browser, and showed the request message on a UART terminal.

  • HTTP Request
