Uploadino

This repository contains a .NET library and a corresponding dotnet tool that can be used to upload a compiled sketch (.HEX) directly to an Arduino board over USB. It talks to the boards bootloader over the serial (USB) connection, much like avrdude does (when invoked from the Arduino IDE, or from the command line).

Compatibility

The library has been tested with the following configurations:

Arduino Model	MCU	Bootloader protocol
Leonardo	ATMega32U4	AVR109
Mega 1284	ATMega1284	STK500v1
Mega 2560	ATMega2560	STK500v2
Micro	ATMega32U4	AVR109
Nano (R2)	ATMega168	STK500v1
Nano (R3)	ATMega328P	STK500v1
Uno (R3)	ATMega328P	STK500v1

How to use the command line application

Download the latest Windows binaries here (.zip file, version 1.0.0).

When running Uploadino.exe without arguments, the application will document its usage:

ERROR(S):
  -file required option is missing.
  -m/--model required option is missing.


  -file     Required. Path to the input file (in intel HEX format) which
                 is to be uploaded to the Arduino.

  -p, --port     Name of the COM port where the Arduino is attached (e.g.
                 'COM1', 'COM2', 'COM3'...).

  -m, --model    Required. Arduino model. Valid parameters are any of the
                 following: [Leonardo, Mega1284, Mega2560, Micro, NanoR2,
                 NanoR3, UnoR3].

A sample command line invocation (for a Mega2560 type Arduino attached to COM4):

Uploadino.exe -file C:\MyHexFiles\myHexFile.hex  -port COM4 -model Mega2560

How to use the .NET library

Link the following nuget package in your project in order to use the Uploadino: https://www.nuget.org/packages/Uploadino/

Alternatively, install the package using the nuget package manager console:

Install-Package Uploadino

or

dotnet add package Uploadino

The following minimal snippet shows how to upload a .HEX file to an Arduino (UNO) board attached at COM port 3:

var uploader = new Uploadino(
    new UploadinoOptions()
    {
        FileName = @"C:\MyHexFiles\UnoHexFile.ino.hex",
        PortName = "COM3",
        ArduinoModel = ArduinoModel.UnoR3
    });

uploader.UploadSketch();

As discussed above, one can try to auto-detect the COM port by omitting it.

Logging

In earlier versions of the library, it emitted log messages through a dependency on NLog. From an architectural point of view, it is suboptimal to be forcing a dependency on a particular logging framework from library code.

A simple IUploadinoLogger interface is exposed from within the library. Implement this interface, and pass an instance into the Uploadino constructor if you want to consume log messages (in varying levels, from Info to Trace).

Implementing the interface using NLog consists of nothing more than this:

private class NLogUploadinoLogger : IUploadinoLogger
{
    private static readonly Logger Logger = LogManager.GetLogger("Uploadino");

    public void Error(string message, Exception exception)
    {
        Logger.Error(exception, message);
    }

    public void Warn(string message)
    {
        Logger.Warn(message);
    }

    public void Info(string message)
    {
        Logger.Info(message);
    }

    public void Debug(string message)
    {
        Logger.Debug(message);
    }

    public void Trace(string message)
    {
        Logger.Trace(message);
    }
}

This library and tool is an fork of this great work
