描述
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.
語法
// set up a new serial port SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin); mySerial.available()
參數
無
回傳
the number of bytes available to read
範例
// 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 loop() {
if (mySerial.available()>0) {
mySerial.read();
}
