In TCPIPConfig.h, the default network configuration must be adjusted to your local network (MAC address, IP\u00a0address and so on).<\/p>\n
In addition, STACK_USE_DNS, STACK_USE_BERKELEY_API and STACK_USE_TCP\u00a0are defined so that the Ethernet board\u00a0can work as a NTP client using the Berkeley Socket.<\/p>\n
<< Operation of the NTP client >><\/p>\n
Initialization:\u00a0\u00a0\u00a0 If the Ethernet board is connected to the Internet for the first time, the current time can be automatically obtained from the NTP server.<\/p>\n
Adjustment of the time:\u00a0\u00a0\u00a0 Every time the RB3 pin (BUTTON 0) is pulled down, the current time will be gotten from the NTP server.<\/p>\n
