LC Studio SD Breakout with Due - RESOLVED

kizin

I have the LC Studio SD Breakout and an Arduino Due. http://www.amazon.com/gp/product/B008B52QQC/ref=oh_details_o00_s01_i00?ie=UTF8&psc=1

I used my multimeter on the ICSP header to locate the 5V. I'm not sure which header I should be using, SPI or ICSP, but I have tried them both after locating their 5V pin.

I posted this question on the Playground and have gotten nothing. No one seems to know if it's even hooked up correctly, so I am posting here.

 

Here are my connections:

 

 

With Due power connector at the bottom left:

 

 

|  a  b  |

|  c  d  |

|  e  f  |

"ICSP"

 

Pin e is 5v.

 

Due    |    SD

c         |    MOSI

d         |    SCK

f          |  MISO

pin 10 |  CS

5v       |  +5

(nc)    | +3.3

GND   | GND (next to +3.3)

 

I have also tried, without success:

I/F Board     Arduino Pin

CS               10

MOSI           11

SCK            13

MISO           12

I have read that those pins don't work that way with the Due, but I really need this to work so my project can move forward, so I tried anyway.

 

I have tried 4 different cards: 1 GB PNY - FAT, 16 GB SDHC SanDisk Ultra (micro-SD w/adapter) - FAT32, 4 GB SanDisk (micro-SD w/adapter) - FAT32, 2 GB Generic (micro-SD w/adapter) - FAT

 

I've used two different sketches, setting 10 as CS: CardInfo example, SimpleAudioPlayer example

 

 

I get

CardInfo:

Initializing SD card...initialization failed. Things to check:

* is a card is inserted?

* Is your wiring correct?

* did you change the chipSelect pin to match your shield or module?

 

 

SimpleAudioPlayer:

Initializing SD card... failed!

 

 

So, here are my initial questions:

1. Is it connected correctly?

2. What else might be wrong?

 

 

Thanks for any assistance.

    Hi kizin

     

    Not familiar with Due, but have tried to use the LCD Studio board and failed, because I was using an incompatible SD card. I have used a different SD Card breakout board successfully.

     

    Below are the  pinouts for the SPI bus header; yours seem to be different

    The pinout image is taken from: http://arduino.cc/en/Reference/SPI

     

    Hope this helps

     

    Best wishes

    PS - doesn't the Due run on 3.3v?

    Thank you very much for your response.

    I went ahead and tested the cards on my Uno using my LinkSprite SD Shield. All of the cards worked.

    I'm embarrassed to say, but my OP was wrong. I labeled MOSI and MISO backwards. I have fixed it in the OP.

    +5 volts is on pin "e" (from the OP).

    The pinout looks like this now:

    |  a  b  |    6  5

    |  c  d  |     4  3

    |  e  f  |     2  1

    "ICSP"

     

    Is that numbering correct? It's caused a lot of confusion for me.

     

    Due    |    SD

    c         |    MOSI

    d         |    SCK

    f          |  MISO

     

    The Due does run at 3.3v, and sends 3.3v signals. It does supply 5v on the ICSP, SPI, and through a pin on the board itself, but I'm pretty sure they are all just used to power boards that require 5v as a power supply. Could 3.3v signals be a problem?

     

    I took out my cheap-ish multimeter to make sure all the connections are good. I found +3.3v on MOSI, SCK, and MISO. If that helps any.

    Hi kizin,

     

    I think this link may have the answer for you:

     

    http://21stdigitalhome.blogspot.co.uk/2013/02/arduino-due-hardware-spi.html

     

    In short, ICSP and SPI on the Due are very different; the link states that you should be using the SPI connector for your SD Card breakout, NOT the ICSP header. The image in this link makes the pin connections quite clear, I think!

     

    I found the link here:  http://forum.arduino.cc/index.php?topic=150084.0

     

    When I get into difficulties with my Arduinos, , I find it useful to go back to something simpler: will the LCD Studio board actually work with a UNO, connecting directly to the Digital pins 10.11.12 & 13, as you described in your original post. The SD Card breakout board I use is connected directly to these pins. I DON'T use the ICSP header on my UNO.

     

    Good luck

    Neil,

     

    Thank you for your help. Obviously using the wrong header would have been a problem. After reading the linked blog entry, I connected the board to the SPI header using the schematic on the arduino.cc forum topic you linked. Unfortunately, that did not solve the problem. So I did as you suggested and tried it on my Uno. It did not work.

     

    With your help, I have determined I have a bad board; which, from what I have read, is not entirely uncommon for these cheap units. Next time I'll know right away how to connect it, too! Thanks again!
