SD Card hookup with FutureTect SD card

KamPutty

Hi all,

Hey, I just got the FutureTech SD card that I want to hookup to the prop...btw, it cost $7 for the complete board!
www.futurlec.com/Mini_SC.shtml

Now, I am having major brain farts here (truth be told, I cannot think today as we had to put our Dog down yesterday )

I'm looking at the Prop Cookbook, and trying to hook up the board, and I cannot match all the pins up (there were no docs with the board)

Since I have already blown an io pin on my usb-prop, I'm alittle nervous about mis-wiring!

So, can anyone help with what I need to wire too on this board?

Thanks all...I'm just gonna sit and cry for awhile

Bob,

thanks for the info...now, according to the "Prop Cookbook", there are 4 connections that are connected from the prop to the sd

#1. P0 --> DO
#2. P1 --> CLK
#3. P2 --> DI
#4. P3 --> CS

Now I need to map the SD end of the futureteck board

#1. DO --> ????
#2. CLK --> CLK(5)
#3. DI --> ????
#4. CS --> ????

Thanks again!

I've always looked at the documentation for the SD card adapter on this site:

http://ucontroller.com/

He has a lot of nice products made for the prop, check it out.

Just scroll down to the SD Card Adapter and click the documentation button.

DATI looks like DI
DATO look like DO
CMD might be CS, try it
There are pullups jumper selectable on the SPI pins.
CS is the same as SSEL. Follow the traces on the board
to make sure it connects to CMD.

Mike that is incorrect, if you check the documentation I talked about it gives pin numbers from the socket to go by. I just don't want to paste his information in the forums without getting his permission since he put a lot of work into it.

Looking at the schematic above, I believe (but am not sure) that:

p0 = do = miso = dat0(7)
p1 = clk = sclk = clk(5)
p2 = di = mosi = cmd(2)
p3 = cs = ssel = cd/dat3(1)

The di/do names are from the perspective of the SD card; consider
that di = mosi and do = miso (mosi=master out slave in, miso=master
in slave out).

If you are concerned about blowing pins, just use 150 ohm resistors
in series on each line and use the slow sdspi.spin code, until you've
gotten it to work, at which point you can remove the series resistors
and go to the faster assembly language routines.

http://pinouts.ru/Memory/sdcard_pinout.shtml gives the pin map to SPI names and ucontroller give the map to prop pin numbers
