ATMEGA128 experiment with ethernet chip ?

[bianchi77]

Guys,

I'm doing ethernet experiment with ATMEGA128
Why can't I use PB4 for CS on ENC28J60 ?
It's working only with PB0 even I change to PB4.

Code :

#define ENC28J60_CONTROL_PORT	PORTB
#define ENC28J60_CONTROL_DDR	DDRB
#define ENC28J60_CONTROL_CS		4
#define ENC28J60_CONTROL_CS_L 	ENC28J60_CONTROL_PORT&=~(1<<ENC28J60_CONTROL_CS)
#define ENC28J60_CONTROL_CS_H 	ENC28J60_CONTROL_PORT|=(1<<ENC28J60_CONTROL_CS)

Does anyone have the same experience ?
How to rectify it ?

Thanks

Whatever is going wrong it's not in the defines you have posted. What is the used library?

I used a library from enc28J60 from AVRlib Library
