SD Card error

system · May 12, 2014, 10:10am

hello,

I'm developing a simple program that logs some data to a sd card.
however the sd card never initializes.
i'm using:
Arduino uno
Sd card shield (http://imall.iteadstudio.com/im120417007.html) (switch at 3.3v)
LCD shield (Gravity: 1602 LCD Keypad Shield For Arduino - DFRobot)

here's my code:

#include <SD.h>
#include <RTClib.h>
#include <LiquidCrystal.h>
#include <Wire.h>
#include <SPI.h>

LiquidCrystal lcd(8,13,9,4,5,6,7);

The SD card is an SPI device. On a 328-based Arduino, that means that it uses pins 10, 11, 12, and 13 AND that you can't use those pins for ANYTHING else.

You are currently trying to use pin 13 for 3 different purposes. Get real.

so, raw solution, discard the lcd shield?

I wouldn't discard it. I'd send it back, and demand my money back. Only idiots design shields that use the SPI pins for non-SPI purposes.

They are nearly as bad as people that decide that pins 2 and 3 MUST be used in place of the hardware serial pins, since those are the only external interrupt pins available on the 328-based Arduinos. Yes, it makes routing the traces easier, but that is no damned excuse.

i meant discard it from the project...

thanks a lot.

i'll try removing the lcd shield and the code to it when i get home a then i'll give it another try.

thanks again!

ok, so i removed the LCD shield and commented all the lcd and led parts of my sketch, still getting initialization failed.

here's the code:

i've been going arround the code for a while now and i can't find the problem... probably it's right in front of my eyes and i cant see it...

Ditch all the crap that has nothing to do with the SD card. You don't need to include RTClib, Wire.h, LiquidCrystal, etc. And do NOT create instances of them.

Have you tried the examples that come with the SD class?

system · May 13, 2014, 11:38am

i'll try making a test sketch only for the sd...
