Ethernet Module Development

New page

This project aims to develop an Ethernet Module, to be used in conjunction with a 8/16 bits embedded system such as the dsPic33F development board.

==Architecture==
*See [http://www.opencircuits.com/Multi-purpose_Embedded_System#TCP.2FIP_Stack here] for block diagram

==Development Roadmap==
===Phase 1===
*Select chips and draw schematic and pcb
*Obtain samples for chip

===Phase 2===
*Device driver
*Create a Linux socket API wrapper in freertos_posix

===Phase 3===
*Reference to Linux socket/lwip, create libraries for
**DHCP client
**HTTP server
***Decide how to get files (html, css, cgi, etc) from nvm (with/without file system)
***Decide an efficient means to create and download web page to nvm
**DNS resolver
**SMTP mail client
**SNMP agent
**TELNET application

===Phase 4===
*Explore wireless-bridge solutions

===Software Implementation===
====Driver====
*Download [http://chungyan5.no-ip.org/vc/trunk/demo_posix/dspic/drivers/?root=freertos_posix dm9000a.c]
*Download [http://chungyan5.no-ip.org/vc/trunk/demo_posix/dspic/drivers/include/?root=freertos_posix dm9000a.h]
*Base on [http://www.freertos.org/ FreeRTOS] and [http://opencircuits.com/DsPIC30F_5011_Development_Board dsPIC33 platform]
*Using POSIX-like API:
**'''int dmfe_open(int flags)''': initialize the Ethernet controller for 10MHz Half-Duplex
**'''int dmfe_close()''': turn off the PHY layer
**'''int dmfe_read(void)''': copy a packet to the default buffer
**'''int dmfe_write(unsigned char device, unsigned char *buf, int count)''': copy count bytes of the data from buf and transmit
**'''void dmfe_interrupt(void)''': process the transmit interrupt from DM9000A

====[[uIP]]====
*Light-weight TCP/IP stack designed for 8-bit/16-bit embedded systems

====[[lwIP]]====
*Light-weight TCP/IP stack designed for 8-bit/16-bit embedded systems
*Consume more resource than uIP
