Question

我尝试使用NANO进行串行写入。这是我目前的代码

＆＃13;

#include "HardwareSerial.h"

long previousMillis = 0;
long interval = 2000;    

void setup() {
  // put your setup code here, to run once:
 pinMode(13, OUTPUT);
 digitalWrite(13, HIGH);
 Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  unsigned long currentMillis = millis();
  if(currentMillis - previousMillis > interval) {
    previousMillis = currentMillis; 


    HardwareSerial serial = Serial;
    serial.write("hello");
  }
}

＆＃13;

然而，当我使用串行监视器监视串行时，我只能

每次串行写入
