Hi guys is anyone using the microSD sniffer & ENC28j60 together?

I know they work as matthew game me his but the wires have popped off and i have no idea how they should go...

microsd sniffer

Dat1 Dat0 CLK VCC GND CMD CD DAT2

ENC28j60

vcc gnd cs reset si scp wcl s0 clk out int

vcc is 5v
gnd is ground

any ideas on working this up?

cheers

If the module has only a 5V VCC input, it would need to be modified for 3.3V operation. Typically, you'll find a 3 pin voltage regulator on the bottom that you'd need to bypass or better replace by a trace.
 
  Other option: supply the 5V from the floppy connector (or another convenient place on the mainboard).
 
  The mapping should be (left=breakout,middle=SD SPI terminology,right=SD connector pin count):
 
  Dat1 Dat0 CLK VCC GND CMD CD DAT2
 
  CD= /CS = Pin 2
  CMD = DI = Pin3
  VCC = Vdd = Pin4
  CLK = SCLK = Pin5
  GND= Vss = Pin6
  Dat0 = DO = Pin7
  Dat2 = Pin1
  Dat1 = Pin8
 
  ENC Module to breakout mapping:
 
  vcc = Pin4 (for 3.3V ENC modules)
  gnd = Pin6
  cs = Pin2
  reset -unused
  si = Pin3
  scp - unused
  wcl = Pin5
  s0 = Pin7
  clk out - unused
  int - 3.3 kOhm - Pin1
 
  Disclaimer: Be careful. You're interfacing directly with the FPGA here. Verify the cabling by measuring the connections from the ENC module to the MicroSD breakout pins (see README in the SDNet package).

thanks
  ive already been using this over the last few weeks but the dupont wires popped off.

thanks again.

any chance of a basic "paint" diagram showing how the two items hook up? you have peaked my interest!!

  Paint? Meh. We're in retro-land. Hence, all I was prepared to offer is ASCII-art. See the README in the archive. EXTERNAL LINK 
SDNet release thread is here EXTERNAL LINK

I’ll do something in Dpaint...
