Hello

Here it is.

It was tested as PlatformIO project with this config (.ini)

platform = atmelavr
board = controllino_maxi
framework = arduino
lib_deps = controllino, ethernet, SPI, MQTT

To return Controllino to the original state, just switch it to DFU mode again and upload the latest ATmega16U2 Arduino HEX file:

Hello,

Ad connecting and reconnecting to Serial port of Controllino and Arduino in general.

In C# when You use SerialPort Class there is SerialPort.DtrEnable Property which enables or disables DTR (Data Terminal Ready) signal during serial communication.

When it is disabled connecting and reconnecting to Controllino (tested on Mini, Maxi and Mega) do NOT cause Controllino to reset.

Here is example of my Class and Constructor I used for tests:



Code:




using System.IO.Ports;
    /// 

    /// Defines the 

    /// 
    public class COMPort : SerialPort

    {
        /// 

        /// Initializes a new instance of the  class.

        /// 
        /// The aPortname

        /// The aBaudRate

        /// The aDataBits

        public COMPort(string aPortname, int aBaudRate, int aDataBits, bool aDtrEnable)

        {

            // open ComPort

            this.PortName = aPortname;

            this.BaudRate = aBaudRate;

            this.DataBits = aDataBits;

            this.Parity = System.IO.Ports.Parity.None;

            this.StopBits = System.IO.Ports.StopBits.One;

            this.Handshake = System.IO.Ports.Handshake.None;

            this.RtsEnable = true;

            this.DtrEnable = aDtrEnable;

        }

    }

And when I open COM port with aDtrEnable=true it causes reset, but when I open COM port with aDtrEnable=false the Controllino (even Arduino UNO and Arduino MEGA) do NOT reset.

It is also possible to use several Controllino devices in a Master-Slave Scenario.

Example scenario see:

~~[img]~~https://i.postimg.cc/3rkZ3XYJ/Controllino-net.jpg%5B/img%5D

Where two “slave” Controllinos are connected to one “Master” Controllino and these 3 devices acts like “one”.

When “Master” acts like “proxy” for TCP messages from “slaves”.

Real setup with logical “1” connected to A0 of each Controllino see:

~~[img]~~https://i.postimg.cc/8cxNFhG3/Controllino-setup.jpg%5B/img%5D

For listening on PC Hercules tool has been used see:

~~[img]~~https://i.postimg.cc/13tbxgZV/Controllino-Hercules-listen.jpg%5B/img%5D

Which receives messages from all 3 devices.
