I recently bought a mini SD Card reader (http://www.adafruit.com/products/254) to use with my Arduino Uno. As I am finally having a chance to try it out, I am getting the following error:
Type any character to start
Can't access SD card. Do not reformat.
No card, wrong chip select pin, or SPI problem?
SD errorCode: 0X1,0X0
I've tried two other miniSD cards, all of which werefirst FAT formatted, and then when tested they gave me the same error message. The SDFat sketch I am using is attached below. I've double & triple-checked all the wiring and it is all correct. I am using short wires (5 inches long) connected to a breadboard.
By any chance, have you seen this kind of error before? Thanks in advance for your help with this!
Code: Select all
// Ported to SdFat from the native Arduino SD library example by Bill Greiman
// On the Ethernet Shield, CS is pin 4. SdFat handles setting SS
const int chipSelect = 10;
/*
SD card read/write
*/
#include <SdFat.h>
SdFat sd;
SdFile myFile;
void setup() {
Serial.begin(9600);
while (!Serial) {} // wait for Leonardo
Serial.println("Type any character to start");
while (Serial.read() <= 0) {}
delay(400); // catch Due reset problem
// Initialize SdFat or print a detailed error message and halt
// Use half speed like the native library.
// change to SPI_FULL_SPEED for more performance.
if (!sd.begin(chipSelect, SPI_HALF_SPEED)) sd.initErrorHalt();
// open the file for write at end like the Native SD library
if (!myFile.open("test.txt", O_RDWR | O_CREAT | O_AT_END)) {
sd.errorHalt("opening test.txt for write failed");
}
// if the file opened okay, write to it:
Serial.print("Writing to test.txt...");
myFile.println("testing 1, 2, 3.");
// close the file:
myFile.close();
Serial.println("done.");
// re-open the file for reading:
if (!myFile.open("test.txt", O_READ)) {
sd.errorHalt("opening test.txt for read failed");
}
Serial.println("test.txt:");
// read from the file until there's nothing else in it:
int data;
while ((data = myFile.read()) >= 0) Serial.write(data);
// close the file:
myFile.close();
}
void loop() {
// nothing happens after setup
}
I think it is time for me to buy some reading glasses
