SoftwareSerial: overflow()
Description
Tests to see if a software serial buffer overflow has occurred. Calling this function clears the overflow flag, meaning that subsequent calls will return false unless another byte of data has been received and discarded in the meantime.
The software serial buffer can hold 64 bytes.
Syntax
mySerial.overflow()
Parameters
none
Returns
boolean
Example
#include <SoftwareSerial.h>
// software serial : TX = digital pin 10, RX = digital pin 11
SoftwareSerial portOne(10,11);
void setup()
{
// Start the hardware serial port
Serial.begin(9600);
// Start software serial port
portOne.begin(9600);
}
void loop()
{
if (portOne.overflow()) {
Serial.println("SoftwareSerial overflow!");
}
// software serial : TX = digital pin 10, RX = digital pin 11
SoftwareSerial portOne(10,11);
void setup()
{
// Start the hardware serial port
Serial.begin(9600);
// Start software serial port
portOne.begin(9600);
}
void loop()
{
if (portOne.overflow()) {
Serial.println("SoftwareSerial overflow!");
}
