Arduino error: no matching function for call to 'ModbusMaster::begin(int&, Stream**)'

[TR.0LL (Gast)]

Hallo,

ich bekomme folgenden Fehler in PlatformIO:

D:\projects\SOLIS_4Gmini_arduino\src\4G_mini.cpp: In member function 'void SOLIS_4G_MINI::begin()':
D:\projects\SOLIS_4Gmini_arduino\src\4G_mini.cpp:21:36: error: no matching function for call to 'ModbusMaster::begin(int&, Stream**)'
  _inverter.begin(_slaveID, &_serial);

4G_mini.h

#ifndef _4G_MINI_H
#define _4G_MINI_H

#include <Arduino.h>
#include <ModbusMaster.h>
#include "registers.h"

class SOLIS_4G_MINI {
public:
  SOLIS_4G_MINI(Stream& serial,uint8_t dere_pin, uint8_t slave_id);
  void begin();

private:
  Stream* _serial;
  int _dere_pin;
  int _slaveID;

};

#endif

4G_mini.cpp

#include "4G_mini.h"

ModbusMaster _inverter;                    //object node for class ModbusMaster


SOLIS_4G_MINI::SOLIS_4G_MINI(Stream& serial,uint8_t dere_pin,uint8_t slave_id) {
  this->_serial = &serial;
  this->_dere_pin = dere_pin;
  this->_slaveID = _slaveID;

}

void preTransmission()
{
}
void postTransmission()
{
}

void SOLIS_4G_MINI::begin() {
  _inverter.begin(_slaveID, &_serial);
  _inverter.preTransmission(preTransmission);         //Callback for configuring RS-485 Transreceiver correctly
  _inverter.postTransmission(postTransmission);
}

Platformio.ini

[env:uno]
platform = atmelavr
board = uno
framework = arduino

lib_deps = 
  https://github.com/4-20ma/ModbusMaster.git

lib_extra_dirs =
  D:\git\lib\SOLIS_4Gmini_arduino

Wie kann man das Problem am einfachsten beheben?

Vielen Dank im Vorraus.

- Fehlermeldung lesen
- Nachschauen was ModbusMaster::begin() wirklich haben will (einen 
Stream&)
- Code adäquat anpassen
