Hi All
I've got a project that sees an Arduino Mega and an ethernet board (w5100 based, cheapo Amazon job so not an official board) hidden away in a rack.
I have a html file on the SD card on the ethernet board that i'd like to be able to update occasionally, and would like to bring the SD card slot out to the back panel. I already had a few of these cables;
however i'm finding that the arduino can't see the card. That's either the micro sd in an adapter, or the file put on to a proper sd card. I own a few cables from a previous project so tried a few and none of them work, so I don't think it's a faulty card.
Has anyone had similar? Anything I can do to make this cable work, or do I need to get a different one? If so then what do you suggest? Needs to be at least 30cm long to get to where I need it.
Thanks
Chris
If the same card fails with all cables then most probably the card is defective. Try the card in a drive without the cable. If that works then all your cables are crap. Or your SD drive is defective of your code?
Can you post the code you are using? It may be a problem with your code. If not, is probably a problem with your SD cards. What formats were the SD cards you tried? If you are using the SD library, I don't think it works with 64 GB cards.
Same card (without SD adapter) works fine in the Arduino (code is just fine).
Same card with SD adapter works fine in a pc.
Cable (via SD adapter) works fine in a pc.
Every element works correctly in other set ups. It's only when you put the Arduino and cable together that it all goes wrong. It's all very strange.
Interesting to hear that similar problems have been reported on here before.
Afraid not, although mine does look everso slightly different inside to your (the resistor and diode are there, but mine's a full size SD socket). Do you have a link to the one you bought?
