Hi,
I have an Arduino MEGA and shielded with TFT with SD card.
When I use "# include <SD.h> everything works ok ..
But when I use "# include <tinyFAT.h> can not open the card
I tried to format on windows FAT(Predefinition) and FAT32
ALL LIBRARIES ARE ORIGINALS:
tinyFAT --> Electronics - Henning Karlsen
the next code return: "Unsupported filesystem"
#include <tinyFAT.h>
#include <avr/pgmspace.h>
byte res;
long msStart, msEnd, msTotal, msAvg, msHigh, msLow;
char *verboseError(byte err)
{
switch (err)
{
case ERROR_MBR_READ_ERROR:
return "Error reading MBR";
break;
case ERROR_MBR_SIGNATURE:
return "MBR Signature error";
break;
case ERROR_MBR_INVALID_FS:
return "Unsupported filesystem";
break;
case ERROR_BOOTSEC_READ_ERROR:
return "Error reading Boot Sector";
break;
case ERROR_BOOTSEC_SIGNATURE:
return "Boot Sector Signature error";
break;
default:
return "Unknown error";
break;
}
}
void setup() {
// Initialize serial communication at 115200 baud
Serial.begin(9600);
Serial.println();
// Initialize tinyFAT
// You might need to select a lower speed than the default SPISPEED_HIGH
res=file.initFAT();
Serial.println(res,HEX);
if (res!=NO_ERROR)
{
Serial.print("***** ERROR: ");
Serial.println(verboseError(res));
while (true) {};
}
Serial.println("This program will measure the average time a call to the writeLn()-function takes.");
Serial.println();
Serial.println("***** Send any character to start *****");
while (!Serial.available()) {};
Serial.flush();
if (file.exists("SPDCHK.FIL"))
file.delFile("SPDCHK.FIL");
file.create("SPDCHK.FIL");
res=file.openFile("SPDCHK.FIL", FILEMODE_TEXT_WRITE);
if (res==NO_ERROR)
{
msTotal=0;
msLow=1000000;
msHigh=0;
Serial.print("<");
for (int cc=0; cc<64; cc++)
{
if (((cc+1)%16)!=0)
Serial.print("-");
else
Serial.print("+");
}
Serial.println(">");
Serial.print(" ");
for (int cc=0; cc<1024; cc++)
{
msStart=millis();
file.writeLn("SpeedCheck - This is just a random line of text.");
msEnd=millis();
msTotal+=(msEnd-msStart);
if ((msEnd-msStart)<msLow)
msLow=msEnd-msStart;
if ((msEnd-msStart)>msHigh)
msHigh=msEnd-msStart;
if (((cc+1)%256)==0)
Serial.print("+");
else if (((cc+1)%16)==0)
Serial.print("-");
}
file.closeFile();
file.delFile("SPDCHK.FIL");
Serial.println();
Serial.println();
}
else
{
switch(res)
{
case ERROR_ANOTHER_FILE_OPEN:
Serial.println("** ERROR: Another file is already open...");
break;
default:
Serial.print("** ERROR: ");
Serial.println(res, HEX);
break;
}
}
Serial.println("Sample size : 1024 samples");
Serial.print ("Average time: ");
Serial.print (msTotal/1024, DEC);
Serial.println(" ms");
Serial.print ("Highest time: ");
Serial.print (msHigh, DEC);
Serial.println(" ms");
Serial.print ("Lowest time : ");
Serial.print (msLow, DEC);
Serial.println(" ms");
Serial.println();
Serial.println("***** All done... *****");
