Ethernet Initialization
eth.init () uses the eth.init (MAC) If you use DHCP instead, and when using a Static IP uses eth.init ((uint8_t *) MAC, IP, MASK, GATEWAY). This section uses a static IP.
- define MAC "\x
\x\x\x\x\x" Should be Replacedwith your MAC - define IP "192.168.77.100" Should belong with your lan.
- define MASK "255.255.255.0"
- define GATEWAY "192.168.77.1"
eth.init((uint8_t*)MAC); Use DHCP for WIZnetInterface eth.init((uint8_t*)MAC,IP,MASK,GATEWAY); IP,mask,Gateway
