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#
it prints FMT done and 15 new lines only...it unable to print the string which we passed to function ddd called inside the function FMTCRD...

How to clear the unwanted character displaying in LCD

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...
