单片机开发 This version of the code is compatible only with the AT89C2051 due to the location of the data buf
This version of the code is compatible only with the AT89C2051 due to the
location of the data buffer and stack in RAM. The code may be modified to
work with the AT89C1051 by relocating or resizing the buffer and stack to
fit into the smaller amount of RAM available in the AT89C1051.

This document describes the uIP TCP/IP stack. The uIP TCP/IP stack is an extremely small implementation of the TCP/IP protocol suite intended for embedded systems running low-end 8 or 16-bit microcon-trollers. The code size and RAM requirements of uIP is an order of magnitude smaller than other gene ...
