If we give Serial data input =GETID it sholud save as String in SD card, then if we give second input it should print in 2nd line SD card as String.once every string Print in SD card then new line should print

void setup()
{
Serial.println(ddd("EDF"));
}
void loop ()
{
getcommand();
}
void getcommand()
{
if(inputdata==SET99FMTCRD#)
{
if(FMTCRD)
{
Serial.print("FMT done");
}
else {
Serial.print("FMT Failed");
}
}
String ddd(String ff)
{
String adddata;
adddata= " Getdata";
ff+= adddata;
return ff;
}
bool FMTCRD()
{
for (j=0;j<=15;j++)
{
Serial.println(ddd("ASDFRTG"));
}
return true;
}


The output i'm getting is:
when the serial begins it prints : EDF Getdata

when we give serial input " SET99FMTCRD#

How to clear the unwanted character displaying in LCD

How to clear the unwanted character displaying in LCD

Click to expand...

Always clear the whole display before updating it.

Is the character always at the end? In the string library there are string functions to eliminate characters from strings.

If you use '#' as the delimiting character on 'strtok()' You can get rid of it...

Thanks for your information...!!!!!
