本文介绍了解决“重新声明为不同类型的符号"错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我目前正在研究 Arduino.我正在使用 Atmega1284 为 Lamp 工作.我看到了一个示例代码，ModbusIP_ENC28J60 -> Lamp.我首先编译它没有添加任何东西，它编译正确.现在，我正在添加 WebSocketServer，因为我希望它也能在 websocket 上工作.我添加了一些必要的行，但最终出现了这个错误:错误:EthernetClass Ethernet"重新声明为不同类型的符号

I'm currently working on Arduino. I'm working for Lamp using Atmega1284. I saw an example code, ModbusIP_ENC28J60 -> Lamp. I first compiled it without adding anything, it compiled properly. Now, I'm adding WebSocketServer, since I want this to work on websocket too. I added few necessary lines, but I ended up with this error:error: 'EthernetClass Ethernet' redeclared as different kind of symbol

我不明白代码有什么问题或我应该更改什么.有人可以帮我解决这个问题吗?

I don't understand what's wrong with the code or what I should change. Can someone help me with this?

我在这里粘贴我的代码以供参考:

I'm pasting my code here for reference:

#include <EtherCard.h>
#include <Modbus.h>
#include <ModbusIP_ENC28J60.h>

#include <WebSocketsServer.h>

WebSocketsServer webSocketServer = WebSocketsServer(8080);

//Modbus Registers Offsets (0-9999)
const int LAMP1_COIL = 100;
//Used Pins
const int ledPin = 9;

//ModbusIP object
ModbusIP mb;

void webSocketEvent(uint8_t num, WStype_t type, uint8_t * payload, size_t lenght) {
    switch(type) {
        case WStype_DISCONNECTED:
            Serial.println("[%u] Disconnected!\n");
            break;
        case WStype_CONNECTED:
            {
                //IPAddress ip = webSocket.remoteIP(num);
            Serial.println("[%u] Disconnected!\n");

        // send message to client
        //webSocket.sendTXT(num, "Connected");
            }
            break;
        case WStype_TEXT:
            Serial.println("[%u] got text!\n");

            // send message to client
            // webSocket.sendTXT(num, "message here");

            // send data to all connected clients
            // webSocket.broadcastTXT("message here");
            break;
        case WStype_BIN:
            Serial.println("[%u] get binary ");
            //hexdump(payload, lenght);

            // send message to client
            // webSocket.sendBIN(num, payload, lenght);
            break;
    }
}

void setup() {
    // The media access control (ethernet hardware) address for the shield
    byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
    // The IP address for the shield
    byte ip[] = { 192, 168, 0, 120 };
    //Config Modbus IP
    mb.config(mac, ip);
    //Set ledPin mode
    pinMode(ledPin, OUTPUT);
    // Add LAMP1_COIL register - Use addCoil() for digital outputs
    mb.addCoil(LAMP1_COIL);

    webSocketServer.begin();
    webSocketServer.onEvent(webSocketEvent);
}

void loop() {
   //Call once inside loop() - all magic here
   mb.task();

   //Attach ledPin to LAMP1_COIL register
   digitalWrite(ledPin, mb.Coil(LAMP1_COIL));

   webSocketServer.loop();
}

帮助我让它发挥作用.
