ENC28J60 doesn't answer
PostPosted: Tue Apr 03, 2007 6:08 am     Reply with quote
Hi!

I'm using the CCS driver for ENC28J60. I ask them a sample code but I never received anything.

I wrote this small program to test the communication between ENC and a PIC18F4520:

Code:

#define ENC_MAC_USE_SPI TRUE
#include "enc28j60.c"
.
.
.
mac_spi_init();
mac_reg_init();
printf("%u\r\n", enc_mac_read_control_byte(ENC_MAC_MAADR1, TRUE));


I get "0" as first mac address value instead 0x11 (sample value).
I defined into enc28j60.c the CS pin, but not the RST one because I tied high the reset pin of ENC like some schematic out there.

May you help me to find out the problem?

Thank you
