protocol stack intended for small 8-bit and 16-bit microcontrollers. 18*10465441SEvalZero<p> 19*10465441SEvalZerouIP 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*10465441SEvalZero<p> 21*10465441SEvalZero<table
