| TCPIP stack problem |

I'm using MPlab v8.33 and CCS complier v4.069. I have pic18F66J60 so I tried to redefine stack for this chip, because it wasn't in the ccstcpip.h. So I stopped all chip options in ccstcpip.h and I added to my main program this code:
| Code: |
#include <18F66J60.h>
#Fuses HS,NOWDT
#use delay(clock=25M)
#define STACK_USE_CCS_PICEEC 1
|
The compiler doesn't show any errors (it compiles it fine), but when I load this program to the controller nothing happens. I tried with simple program and the controller works. So I think my modification is the problem.
What must I do to use the tcpip stack with 18F66J60? What do I have to change and where??
Thanks! |

I tried with loading ex11.c from the examples in the stack. So as result I have the first 2 messages changing on the screen:
\fCCS TCP/IP Tut. and \nNo Ethernet. They are changing in around 0.5s.
Any ideas where to search for the problem???
Thanks! |

Hi, again!
I`ve made a simple change in the ccstcpip.h :
| Code: |
#elif STACK_USE_CCS_PICEEC
#include <18F66J60.h>
#fuses NOWDT, NODEBUG, HS
#use delay(clock=25M)
|
and this:
| Code: |
#define USER_LED1 PIN_A0
#define USER_LED2 PIN_A1
*0xF92=*0x00;
|
I`ve made a simple program using ex11.c
| Code: |
delay_ms(500);
MACAddrInit();
*0xF92=*0x00;
output_high(PIN_A0);
output_high(PIN_A1);
IPAddrInit();
StackInit();
while(1)
{
StackTask();
output_high(PIN_A0);
output_high(PIN_A1);
}
|
But in this case the 2 leds must light continiously but they flash. I double check but the controller is not restarting. Is this a problem??
When I connect a switch to the pcb, it doesn`t show a new device connected, so I think the stack is not working, but .... |

Try #use FAST_IO(A) - this will require you setting the port a TRIS settings manually.
