NodeMCU的上传问题

问题描述

将代码从arduino IDE上传到我的NODEMCU Lua V3 ESP8266 WIFI时遇到了此类问题。

错误：

这是我连接超声波传感器和NodeMCU的代码。

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth[] = "-2fX0ap9fZmfV1sZLpw06ab6WNvagomb";
char ssid[] = "BlazingSpeed-TIME2.4G";
char pass[] = "1bwf3988";

const int trigPin = D0;
const int echoPin = D1;

long duration;
int distance;

void setup() {
  // put your setup code here,to run once:
  Serial.begin(9600);
  Blynk.begin(auth,ssid,pass);
  pinMode(trigPin,OUTPUT);
  pinMode(echoPin,INPUT);
}

void loop() {
  // put your main code here,to run repeatedly:
  digitalWrite(trigPin,LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin,HIGH);
  delayMicroseconds(10);
  digitalWrite(trigPin,LOW);
  duration = pulseIn(echoPin,HIGH);
  distance = duration*0.34/2;

  if (distance <= 10){
    Blynk.virtualWrite(V0,255);
  }
  else{
    Blynk.virtualWrite(V0,0);
  }
  if (distance <= 6){
    Blynk.virtualWrite(V1,255);
  }
  else{
    Blynk.virtualWrite(V1,0);
  }
  if (distance <= 3){
    Blynk.virtualWrite(V2,255);
  }
  else{
    Blynk.virtualWrite(V2,0);
  }
  Blynk.run();
}
