    We have done practices with JPEG Trigger board and LinkSprite JPEG Color Camera but we have found one problem that appear be reading memory card microSD. The problem with JPEG Trigger board consist in that blink red led even if we formatted the memory card is FAT16.

    We have used two memory cards: 1. MicroSD 1GB 2. SanDisk 2GB Both memory cards were FAT16 formatted as follows: 1. Windows format: FAT(predetermined) 2. Ubuntu: GParted > FAT16 format 3. SDFormatter software (on Windows): Format type > Quick, Format Size Adjustment > Off Despite testing, red led blink.

    Too, we downloaded the last source code for arduino that appears in this product web site. We upload this code to JPED Trigger. We perform same tests but this does not solve the problem.

    We do follow the code and found that the program ends in follows line:

    //Initialize the SD Card
    //If the card initialization fails, blink the LED and stop the program
    
    if(!(MemoryCard.begin())){
        systemStatus=PROCESSING;
        Serial.println(systemStatus); //Problem!!!    
        while(1);    
     }
    

    This means that memory memory card does not start well. Why can be this? What can we do for solve the problem?

    Thanks for comments.
