I've done all connections like the help says, using pic18f452, enc28J60 with 8MHz xtal and 74hct08N.
Its very strange i've configured the pic to run at 32Mhz with hs+pll, but the button to debug is enabled only if I compile the project without the line Spi_Ethernet_doPacket(); if I uncomment this line the debuger cannot be runned, and the pic doesnt works, my led blink routine doesnt works, if I comment just this line the led starts to blink.
should the enc28j60 leda or ledb be on without the mcu connection ? because mine is always off.
here is my code:
Code: Select all
program Lan;
uses eth_enc28j60_utils, //this is where you should write implementation for UDP and HTTP
eth_enc28j60;
{***********************************
* RAM variables
*}
var myMacAddr : array[6] of byte {= (0x00, 0x14, 0xA5, 0x76, 0x19, 0x3f)} ; // my MAC address
myIpAddr : array[4] of byte {= (192, 168, 20, 60)} ; // my IP address
gwIpAddr : array[4] of byte {= 192, 168, 1, 1 } ; // gateway (router) IP address
ipMask : array[4] of byte {= 255, 255, 255, 0 } ; // network mask (for example : 255.255.255.0)
dnsIpAddr : array[4] of byte {= 192, 168, 1, 1 } ; // DNS server IP address
procedure Init;
begin
PORTC := 0;
TRISC := 16; //RC4 input, others output. //Is this necessary for spi ?

Spi_Ethernet_Init(PORTC, 0, PORTC, 1, myMacAddr, myIpAddr, Spi_Ethernet_FULLDUPLEX) ;
// dhcp will not be used here, so use preconfigured addresses
Spi_Ethernet_confNetwork(ipMask, gwIpAddr, dnsIpAddr) ;
end;

Init();
while (True) do

if PORTC.6 = 1 then
PORTC.6 := 0 else
PORTC.6 := 1;
Delay_ms(150); //Should be commented when Spi_Ethernet_doPacket is uncommented.
//Spi_Ethernet_doPacket(); // Uncoment this and the pic stops working
end;
end.
Thanks in advance
