W5100E01-AVR User ’s Manual <Fig 3.12: DisplayPingStatistics()> Ping request program is, as explained previously, a program that uses ICMP protocol which is running on IP Protocol. In case of using ICMP channel at W5100, as shown in <Fig 3.11> and <Fig 3.13>, IP protocol to be used must be decided. The socket must be created after calling setIPProtocol(s, IPPROT_ICMP). IP_RAW channel must be created by calling socket(s,SOCK_IPL_RAW,port,flag) when creating the socket. In case of closing ICMP Socket, setIPProtocol(s, 0x00) should be called after close(s) and clear the ICMP Flag which was previously set. 46 © Copyright 2007 WIZnet Co., Ltd. All rights reserved.
