DACWWW - July 2003
This was my attempt at writing a TCP/IP stack on a Microchip PIC MCU's. The motivation for doing this was insanity. While this has been done many times before, I was inspired by Vincent Sanders wwwpic2 to do it all over again.
The test board contained a PIC16F84A and a MAX232 to interface with the PC Comm2 port. Slip was used at both ends at the Interface layer. The basics or the IP protocol were implemented. TCP was included and packets were captured but work stalled when I ran out of memory on the chip, so I was going to migrate it to the PIC16F877a (that includes RS232).
I did implement ICMP echo, and was able to ping the chip. The title of this page was the projects goals, a tiny web server. I'll put the breadboard together again and take some photos. etc.
You can download the ASM source hereI have uploaded the relevant rfc's to this server for reference, however if you want up to date versions please visit the RFC Editor.
