没有匹配功能可调用“ Nextion :: Nextion（SoftwareSerial＆）”？

Question

[在此处输入图片描述] [1]

当我尝试将经过验证的代码上传到mega 2560 arduino时出现此错误。

我想将Nextion HMI与arduino mega 2560连接起来。

#include <Nextion.h>
#include <NextionPage.h>
#include <NextionButton.h>
#include <SoftwareSerial.h>

SoftwareSerial HMISerial(10, 11);  
Nextion nex(HMISerial);
NextionPage pgButton(nex, 0, 0, "pgButton");
NextionButton button(nex, 0, 1, "bEgButton");

void setup()
{
  Serial.begin(9600);
  pinMode(13, OUTPUT);

  nextionSerial.begin(9600);
  //nex.init();
