ETH. SHIELD DFR0125 + DFRMEGA SD PROBLEM
femur 2012-11-27 06:50:22 6098 Views5 Replies Hi, im stuck testing a DFR0125 eth+sd shield V2.0 with an DFRMega V2.0 board, i don´t seem able to use the SD card ... so far i´ve tested changing the pinmode 53 to OUTPUT and HIGH and SPI CS to 8 and 4 but no luck, also tried with 2 different cards one formatted as FAT and the other as FAT32 ... so far i only get this on my serial monitor:
[b][i]Initializing SD card...Wiring is correct and a card is present.
Card type: SD2
Could not find FAT16/FAT32 partition.
Make sure you've formatted the card[/i][/b]
The code i am using is (On Arduino IDE 1.01):
[code]#include <SD.h>
// set up variables using the SD utility library functions:
Sd2Card card;
SdVolume volume;
SdFile root;
const int chipSelect = 8;
void setup()
{
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
Serial.print("\nInitializing SD card...");
pinMode(53, OUTPUT); // change this to 53 on a mega
digitalWrite(53, HIGH);
// we'll use the initialization code from the utility libraries
// since we're just testing if the card is working!
if (!card.init(SPI_HALF_SPEED, chipSelect)) {
Serial.println("initialization failed. Things to check:");
Serial.println("* is a card is inserted?");
Serial.println("* Is your wiring correct?");
Serial.println("* did you change the chipSelect pin to match your shield or module?");
return;
} else {
Serial.println("Wiring is correct and a card is present.");
}
// print the type of card
Serial.print("\nCard type: ");
switch(card.type()) {
case SD_CARD_TYPE_SD1:
Serial.println("SD1");
break;
case SD_CARD_TYPE_SD2:
Serial.println("SD2");
break;
case SD_CARD_TYPE_SDHC:
Serial.println("SDHC");
break;
default:
Serial.println("Unknown");
}
// Now we will try to open the 'volume'/'partition' - it should be FAT16 or FAT32
if (!volume.init(card)) {
Serial.println("Could not find FAT16/FAT32 partition.\nMake sure you've formatted the card");
return;
}
// print the type and size of the first FAT-type volume
uint32_t volumesize;
Serial.print("\nVolume type is FAT");
Serial.println(volume.fatType(), DEC);
Serial.println();
volumesize = volume.blocksPerCluster(); // clusters are collections of blocks
volumesize *= volume.clusterCount(); // we'll have a lot of clusters
volumesize *= 512; // SD card blocks are always 512 bytes
Serial.print("Volume size (bytes): ");
Serial.println(volumesize);
Serial.print("Volume size (Kbytes): ");
volumesize /= 1024;
Serial.println(volumesize);
Serial.print("Volume size (Mbytes): ");
volumesize /= 1024;
Serial.println(volumesize);
Serial.println("\nFiles found on the card (name, date and size in bytes): ");
root.openRoot(volume);
// list all files in the card with date and size
root.ls(LS_R | LS_DATE | LS_SIZE);
}
void loop(void) {
}[/code]
Any help much appreciated!!!!

2012-11-28 19:48:11 Have you any other micro SD card in hand? I think use the FAT16 format is much better for Arduino maybe.
I will try it with my 2g micro SD card classic 4 later in this week also. Keep in touch! Lauren

femur 2012-11-28 01:18:48 I think the sample included in the sdfat library should work.
I remember I tested it on my SD card when the official library can't detect my card. Lauren

Lauren 2012-11-28 01:07:56 Hi, thanks for your reply.
Do you have any piece of code i can use to test that you´re sure to be working?
Regards femur

femur 2012-11-28 00:31:23 1. The cs pin for the SD card should be D4.
2. I think you could try to use the sdfat library for Arduino. Here's a link.
[url=http://code.google.com/p/sdfatlib/downloads/list]http://code.google.com/p/sdfatlib/downloads/list[/url]
Hope it works. ;)
