W5100 Spi Driver

An ASM driver for communicating with the Wiznet W5100 Ethernet IC using SPI. This driver launches a COG that handles FAST reading and writing to the W5100.

Overview

All-in-one Ethernet Controller : Hardware TCP/IP, MAC PHY

Fully hardwired network protocol 

Direct Indirect Bus and SPI for Host Interface

Stable Data Communication

The W5100 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier Internet connection for embedded systems.

W5100 suits users in need of stable Internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, , which has been proven through various applications over many years. W5100 uses a 16ytes internal buffer as its data communication memory.

By using W5100, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller.

It is possible to use 4 independent hardware sockets simultaneously. BUS Direct   Indirect SPI Serial Peripheral Interface are provided for easy integration with the external MCU.

An ASM driver for communicating with the Wiznet W5100 Ethernet IC using SPI. This driver launches a COG that handles FAST reading and writing to the W5100. There are routines in both ASM and SPIN for establishing communication and transferring data and settings.

See the file for further instructions on usage. Included in the Auxiliary files is a demo demonstrating how to use the driver. The Propeller will receive UDP frames and then echo the data back to the sender.

0.6 - Updated the file for various bugs pointed out to me in PM and on the forum. I also reviewed the tx/rx routines for UDP/TCP to be sure they were the same between the Indirect/Parallel code and the SPI code.

Please note that the most up-to-date code may be available via Google Code:

originally posted by Anonymous on 2011-01-03 :41 I have found a bug in the TxUDP routine that truncates packets when the packet being sent wraps around the end of the buffer. I have uploaded a corrected version in the forum thread Update to Spinneret Serial SPI driver to fix problem with truncated UDP packets in the Spinneret forum. -jstjohnz
