Description</h2>uIP is an implementation of the TCP/IP protocol stack intended for small 8-bit and 16-bit microcontrollers. <p>uIP 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. <p><table border="0" cellpadding="0"
