this code shows how to use the ENC28J60 mini library : * the board will reply to ARP & ICMP echo requests * the board will reply to UDP requests on any port : * returns the request in upper char with a header made of remote host IP & port number * * target devices : * any PIC with integrated SPI and more than 4 Kb ROM memory * 32 to 40 MHz clock is recommended to get from 8 to 10 Mhz SPI clock, * otherwise PIC should be clocked by ENC clock output due to ENC silicon bug in SPI hardware * if you try lower PIC clock speed, don t be surprised if the board hang or miss some requests ! * tested with PIC16F877A@10Mhz on EasyPIC3 board-this code shows how to use the ENC28J60 mini library : * the board will reply to ARP & ICMP echo requests * the board will reply to UDP requests on any port : * returns the request in upper char with a header made of remote host IP & port number * * target devices : *
