Hello everyone I have an Arduino Duelminove and a MicroSD Module from libelium.
I have just tried to write in a USD Card by using the SD_uFAT code from but I have a problem, I can only save the data if I have the
Arduino IDEʼs Serial Monitor open.
Has you see bellow I want to continuous write in the uSD Card when I power supply the sensor board without using the Arduino IDEʼs Serial Monitor
Can you help me?
Tanks in Advance.
#include "SDuFAT.h"
// define the pin that powers up the SD card
#define MEM_PW 8
// help string to be sent to the serial port
#define HELP "H help\nL file info\nD delete\nP append string\nW init file and write\nR dump to serial\nA append text\n"
void setup()
  // on my MicroSD Module the power comes from a digital pin
  // I activate it at all times
  pinMode(MEM_PW, OUTPUT);
  digitalWrite(MEM_PW, HIGH);
  // configure the serial port to command the card and read data
void loop()
    SD.print("hola.txt","hola caracola\n");
    Serial.print("Esta Aberta: \n");
