Extend SDcard Reader

[ant0ny]

Hi. I have the GT2560 in a Geeetech Pursa I3 X (8mm Acrylic). Everything is good... I love it.

The one problem I have is big hands and getting the SDcard in and out of the slot. I tried using one of those SD card extender from ebay and it didn't work.

I was just given this Geeetech Arduino SD card Module http://www.geeetech.com/wiki/index.php/ ... ard_Module

I found a pinout of the GT2560 SDcard reader here:

From this forum post: http://www.geeetech.com/forum/viewtopic ... 20&p=27978

The SD Module has the pins labled... so is it possible for me to just match the pins and it will work?

If this module is not possible to be used is there another way I can get a more accessible SD slot?

Thanks Antony

I think it will work, use the dupont cables to connect the sd card and lcd, then it will wrok.

Mark thanks for the quick reply.

Is there another source for the GT2560 SDcard pinout?

I assume power is the pin above the ground by looking at the cable and I can check that with my meter but what would the CS pin be?

[Mark]

uh...seems there's no cs pin on the board, so don't know how to do it too...

[ant0ny]

Ok here pin 4 is marked CS



Here this pin is marked SS

I am not sure what to do and what would happen if I connect it and it's wrong?

[Mark]

they are the same pin, don't worry that.

[ant0ny]

they are the same pin, don't worry that.

So you are saying "CS" and "SS" are the same pin?

The VCC to GND pin measures 3.3v and with my limited knowledge these are the only 2 pins I can confidently confirm.

So I tried to connected the SD reader (it has both 3.3 and 5v input) but I haven't got board to recognize it yet.

I emailed Sherry directly from the Tech Support to get a clarification on the pinout of the GT2560 as I can't seem to find any information that confirms anything... each bit of information I find either is for anther board or inconsistent.

[Mark]

yeah the "SS" on the baord is "CS" on the SD card. are you sure you need 3.3V not 5V? I think it needs 5V to get it work.

[ant0ny]

If I measure the pins from the GT2560 it has 3.3v going to the SDcard.

But I have found a huge stumbling block.

If you disconnect the SD card reader cable from the LCD2004 unit the LCD wont work. It lights up and shows the info but you can't use the knob to scroll the menu... so I assume one or more of the unused pins like the PL7, PG1 or PD7 on the pinout (if it's correct) are needed.

I need better pinouts of all the parts to work this out.

[Mark]

maybe use extra dupont cables to connect all the other pins needed for the LCD see if it works.
