Description</h2> 17uIP is an implementation of the TCP/IP protocol stack intended for small 8-bit and 16-bit microcontrollers. 18<p> 19uIP provides the necessary protocols for Internet communication, with a very small code footprint and RAM requirements - the uIP code size is on the order of a few kilobytes and RAM usage is on the order of a few hundred bytes. 20<p> 21<table border="0"
