SoftwareSerial: peek
Description
Return a character that was received on the RX pin of the software serial port. Unlike read(), however, subsequent calls to this function will return the same character.
Note that only one SoftwareSerial instance can receive incoming data at a time (select which one with the listen() function).
Parameters
none
Returns
the character read, or -1 if none is available
Example
SoftwareSerial mySerial(10,11);
void setup()
{
mySerial.begin(9600);
}
void loop()
{
char c = mySerial.peek();
}
void setup()
{
mySerial.begin(9600);
}
void loop()
{
char c = mySerial.peek();
}
