Get the number of bytes (characters) available for reading from a software serial port. This is data that's already arrived and stored in the serial receive buffer.
mySerial.available()
none
the number of bytes available to read
// include the SoftwareSerial library so you can use its functions:
#include <SoftwareSerial.h>
#define rxPin 10
#define txPin 11
// set up a new serial port
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin)
;
void
setup
(
) {
// define pin modes for tx, rx:
pinMode
(rxPin,
INPUT
)
;
pinMode
(txPin,
OUTPUT
)
;
// set the data rate for the SoftwareSerial port
mySerial.begin
(
9600
)
;
}
void
