Serial.availableForWrite()
설명
쓰기 작업을 차단하지 않고 직렬 버퍼에 쓸 수있는 바이트 (문자) 수를 가져옵니다.
문법
Serial.availableForWrite()
Arduino Mega only:
Serial1.availableForWrite()
Serial2.availableForWrite()
Serial3.availableForWrite()
매개변수
- Nothing
반환값
- 쓰기 가능한 바이트 크기
예제 코드
String myString = "Welcome to ArduinoGetStarted.com!\n";
void setup() {
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
int wlen = Serial.availableForWrite();
// prints the received data
Serial.print("TX buffer size: ");
Serial.println(wlen);
}
void loop() {
// check if Tx buffer is enough to write the string
if (Serial.availableForWrite() > myString.length()) {
// prints the string
Serial.print(myString);
delay(1000);
}
}
- 시리얼 모니터에 결과:
COM6
