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.

  1. define MAC "\x\x\x\x\x\x" Should be Replaced with your MAC
  2. define IP "192.168.77.100" Should belong with your lan.
  3. define MASK "255.255.255.0"
  4. 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
