Hi guys!
I bought one of these ethernet modules:
I wired it up as the following:
VCC -- 3.3V
GND -- GND
CS -- 10
SCK -- 13
SO -- 12
SI -- 11
After I connect the module to the board,the red power indication LED lights up,but none of the ethernet LEDs on the front of the connector while it is connected to my router.
Should the ethernet LEDs light up or blink even if just power is applied to the module and connected to my router?If yes then is my module factory defective?
Test code:
#include <EtherCard.h>
#define STATIC 0 // set to 1 to disable DHCP (adjust myip/gwip values below)
// mac address
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x31 };
// ethernet interface ip address
static byte myip[] = { 192,168,0,200 };
// gateway ip address
static byte gwip[] = { 192,168,0,1 };
// LED to control output
int ledPin10 = 9;
byte Ethernet::buffer[700];
char const page[] PROGMEM =
"HTTP/1.0 503 Service Unavailable\r\n"
