c++ - 如何处理 Arduino 中 M5Stack 库抛出的编译错误

问题描述

我目前正在尝试使用 ESP32 芯片对我的 M5Stack 进行编程。我下载了（或至少我认为）上传到开发板所需的所有依赖项，但我什至无法编译我的程序。我通过板管理器下载了 ESP32，我按照他们网站上的 M5Stack 教程进行操作，似乎在他们的库本身中发现了错误。我不知道如何解决，下面是我的代码，下面是我收到的错误消息。

#include <M5Stack.h>
#include <Wire.h>
#define SPEAKER_PIN 25
#include "config.h"

AdafruitIO_Feed *voltage1 = io.feed("V1");
AdafruitIO_Feed *voltage2 = io.feed("V2");
AdafruitIO_Feed *curr = io.feed("Current");

void setup() {
  // put your setup code here, to run once:
  M5.begin(true, true, true, false);
  Serial.begin(115200);
  dacWrite(25,0);
  M5.Lcd.fillScreen(BLACK);
  M5.Lcd.setTextSize(5);

  // wait for serial monitor to open
  while(! Serial);

  Serial.print("Connecting to Adafruit IO");

  // connect to io.adafruit.com
  io.connect();

  // wait for a connection
  while(io.status() < AIO_CONNECTED) {
    Serial.print(".");
    delay(500);
  }

  // we are connected
  Serial.println();
  Serial.println(io.statusText());


//  ads.getAddr_ADS1100(ADS1100_DEFAULT_ADDRESS);
//  ads.setGain(GAIN_ONE);
//  ads.setMode(MODE_CONTIN);
//  ads.setRate(RATE_32);
//  ads.setOSMode(OSMODE_SINGLE);
//  ads.begin();
}

void loop() {

  io.run();

  // put your main code here, to run repeatedly:
  float v1 = (float)analogRead(36) / 4096 * 17.4  * 0.975;
  float v2 = (float)analogRead(35) / 4096 * 17.4 * 0.975;
  float current = (float)analogRead(5);


  Serial.print("v1: ");
  Serial.print(v1);
  Serial.println("V");
  Serial.print("v2: ");
  Serial.print(v2);
  Serial.println("V");

  M5.Lcd.setTextColor(WHITE);
  M5.Lcd.setCursor(10, 10);
  M5.Lcd.print("V1: ");
  M5.Lcd.print(v1);
  M5.Lcd.print("V");

  M5.Lcd.setTextColor(WHITE);
  M5.Lcd.setCursor(10, 70);
  M5.Lcd.print("V2: ");
  M5.Lcd.print(v2);
  M5.Lcd.print("V");

  M5.Lcd.setTextColor(WHITE);
  M5.Lcd.setCursor(10, 140);
  M5.Lcd.print("Current: ");
  M5.Lcd.print(current);
  M5.Lcd.print("A");
  delay(500);

  M5.Lcd.setCursor(10, 10);
  M5.Lcd.setTextColor(BLACK);
  M5.Lcd.print("V1: ");
  M5.Lcd.print(v1);
  M5.Lcd.print("V");

  M5.Lcd.setCursor(10, 70);
  M5.Lcd.setTextColor(BLACK);
  M5.Lcd.print("V2: ");
  M5.Lcd.print(v2);
  M5.Lcd.print("V");

  M5.Lcd.setTextColor(BLACK);
  M5.Lcd.setCursor(10, 140);
  M5.Lcd.print("Current: ");
  M5.Lcd.print(current);
  M5.Lcd.print("A");


  Serial.print("sending v1-> ");
  Serial.println(v1);
  voltage1->save(v1);

  Serial.print("sending v2-> "); 
  Serial.println(v2);
  voltage2->save(v2);

  Serial.print("sending Current-> ");
  Serial.println(current);
  curr->save(current);

}

错误输出：

解决方案

首先你应该做你的编译器想要的：

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

这提供了更多详细信息，如果解决方案不起作用，请编辑您的问题并用详细的信息替换编译器输出。在您的程序中手动包含缺少的库

#include <WiFi.h>
#include <SD.h>
#include <M5Stack.h>
#include <Wire.h>

并检查您拥有的依赖项

#include "config.h"

由于缺少文件，我无法编译
