I would like to have a dump function that dumps all the contents of the
file to the Serial port. Also, if there is a function that read the
contents of the file without clearing the contents.
Thanks

Here are my questions:
1. Which filesystem is your lib supporting?
2. There are examples how to use this lib with the append mode. Is it
possible to use read - and write mode and seek the position?
3. Is it possible to create/remove files and folders and reading objects of
the current working path?
thanks

The "append" function will fail if the file "data.log" is empty (zero bytes
length).
There's a work around by now, just write one single character to it, that's
it. Of course, if you put a line of characters (like a comment) it will
work too.
The pseudo-code to fix this bug is included in the nanofat.cpp, as soon as
I have some spare time I'll fix it.

Hello,
I'm using filelogger.V0.6 and the sd card shield produced by seedstudio
(http://www.seeedstudio.com/depot/sd-card-shield-for-arduino-v21-p-492.html) on
a linux machine and Arduino Duemilanove board.
When trying to compile the filelogger example it gives me the list of
errors listed below. They all refer to ._Spi.cpp:1
Any ideas on how to solve this???
Many thanks!

#include "FileLogger.h"
void setup(void)
{
byte buffer[] = "Hello World!";
FileLogger::append("data.txt", buffer, 12);
}
void loop(void) {}
Trying to run this piece of code, Cant see any appended data in data.txt file.
which is not empty? what could be the issue?

What steps will reproduce the problem?
1. Use Seeed Studio Stalker board
http://www.seeedstudio.com/depot/seeeduino-stalker-atmega-328-p-600.html
With ATmega328P and microSD card holder.
2. Use SanDisk µSD 2GB card
3. Use FileLogger library April 2009 and try to append data to an existing
top-level file that is 1 byte long.
All I ever get is initialisation failure when calling FileLogger::append().
The CPU runs on 3.3V, the card is within a few cm of the CPU, so I don't see a
problem with long cables or some such.
It's a common card too, can't get anything smaller than that.
As far as I can tell, the card is formatted with FAT16. I used mkdosfs -n msdos
-v -F 16 /dev/sde1
Tested with the FileLoggerDemo.
No good. :(
Works fine with SdFat, so I doubt it's a hardware problem.

The function "locateFileStart" is writing beyond the end of the array
"cookedName". In both "for loops" the test should be "i < 11" instead of
"i < 12".
See below:
char cookedName[11];
for(int i = 0; i < 12; ++i) {
cookedName[i] = 0x20;
}
for (int i = 0, j = 0; i < 12 && filename[i]; ++i) {
if (filename[i] != '.') {
cookedName[j] = filename[i] >= 96 ? filename[i] - 32 : filename[i];
++j;
} else {
j = 8;
}
}

Hello, in arduino Mega the pins for SPI are different.
This is what I did to spi.h to address the change:
#if defined(__AVR_ATmega1280__)
// arduino mega
#define SS_PIN 53
#define MOSI_PIN 51
#define MISO_PIN 50
#define SCK_PIN 52
#else
#define SCK_PIN 13
#define MISO_PIN 12
#define MOSI_PIN 11
#define SS_PIN 10
#endif
I'm in windows now, so I can't make a diff path right now. I send you my
own spi.h.
Thank you very much.

Attachments:
Line 51 in mmc.h
Line 25 in Spi.h
Line 24 in FileLogger.h
change
#include <WProgram.h>
to
#include <Arduino.h>
It is very important to remember this! note that if you are using Arduino 1.0
IDE, change "WProgram.h" to "Arduino.h"

MMC library has built in support for the SPI dialog, so both SPI and MMC
layers are mixed. I'd like to remove the SPI part of MMC and couple MMC to
the Arduino Spi library, so we can have both layers clearly defined.

Writting to the file may fail when crossing the cluster boundary (16Kb, as
each cluster is composed of 32 sectors, 512 bytes per sector), so some data
may be lost.
Will be fixed ASAP, in the meantime don't trust this library to save
important data.
