| 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).

| 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
