Hi,

I've tried to compile the code but the compiler says that 4 source code files are missing:

Source file 'Firmata\AnalogPinMapping.cs' could not be found
Source file 'Firmata\AnalogState.cs' could not be found
Source file 'Firmata\ProtocolVersion.cs' could not be found
Source file 'Firmata\StringData.cs' could not be found

Could you check this issue?
Thanks

I'm trying to get a value from an analog input. I have tested with a standard arduino sketch together with a potentiometer and I'm getting values between 0 - 1023 as expected. However when I try to do the same using SolidSoils library I get the value 0 every time. It can recognize values from digital ports though. Maybe I don't understand how to use the library correctly. Do I need to set AnalogReportMode to true for the channel?

Using Firmata version 2.5.2.

Code:

private void ReadButton_Click(object sender, EventArgs e)
{
            //initialize connection to Arduino
            var connection = new SerialConnection("COM5", SerialBaudRate.Bps_57600);
            var session = new ArduinoSession(connection, timeOut: 250);

            session.SetDigitalPinMode(16, PinMode.AnalogInput);
            PinState ps = session.GetPinState(16);
            MessageBox.Show(ps.Value.ToString() + " " + ps.Mode.ToString() + " " + ps.PinNumber.ToString());
            Thread.Sleep(500);
            connection.Close();
}

I know it's a little far fetched since there hasn't been much activity here, but is there any way to connect directly to a specific COM Port and/or baud rate without searching? I have been trying everything I could with the docs, and the query method won't work for me.

How to send string to arduino?
I have tried using sendStringData but I get exception 'The method or operation is not implemented.'

Thanks.

Hi,

in windows 10 i'm not able to view the chm file, i can see the tree of the documentation but when i click a section nothing happen.

I was trying to find out a solution to get working the I2C communication, when i try to send data nothing happens! I dunno why but without a documentation i can't find out a solution.

this is my code:

        for (int i = 0; i < 255; i++ )
            session.WriteI2C(0x20, new byte[] { Byte.Parse(i.ToString()) });

i've tryed to put up ALL possibile combinations, but nothing happens (i've wired a PCF8574 with a common double relay board, so in any case i must heard the coil switching)...

Can i have a documentation working or i am doing something wrong opening it?

Thank you in advice for your reply, and compliments for the great work!

Is there any methods as "sendSysex" to customize protocol? SendStringData doesn't work fine in my project and I'd like to manage commands from SolidSoils or I fault to use that method.

Thanks

I'm using Visual Studio 2017 (15.2)
Using an Arduino Due on programming port (COM5).

I've changed all 'COM3' strings to 'COM5'.

I am trying to run the project "Solid.Arduino.Run". I compiled and uploaded StandardFirmata.ino from https://github.com/firmata/arduino/blob/master/examples/StandardFirmata/StandardFirmata.ino

base.Open(); seems to throw the above Exception.

Hi,
I tried to use Arduino Leonardo with the latest Solid Arduino and Standard Firmata 2.5.8., but up to now I had no luck. My Arduino not answered on any command I sent.
The Microsoft Windows Remote Experience was working perfectly.
Then I made some investigation, so I used serial port monitor to find out what happening.
The only difference I realized that Microsoft Windows Remote Experience is turning DTR signal high each time it communicates, but Solid Arduino not.
In the source code of SolidSoils Arduino where the serial port opened I put the following:
base.DtrEnable = true;
Since this change the software is works also with Arduino Leonardo

https://github.com/SolidSoils/Arduino/blob/master/Solid.Arduino/ArduinoSession.cs#L611

0~7 bytes 8

Hi,

I've compiled the library and run the basic example code so am happy that I can connect to the arduino
but when I try to set pin 13 high with the following:

firmata.SetDigitalPinMode(13, PinMode.DigitalOutput);
firmata.SetDigitalPin(13, 1);

Nothing happens - when I try the firmata test utility here I can set the pin ok and it lights the onboard led - what am I missing?

Any ideas on how to debug?

Hi all,
Help me initial project.

but not working.

I just found your library, and haven't browsed your code yet to see how difficult it would be...

I would like ot propose adding a TCP/IP socket interface to your library, enabling it to talk to Arduinos using the serial-to-wifi modules, like the ESP-8266, since these are very inexpensive, and easy to configure (I'm using several in Arduino projects already), and they present like any other serial-connection, once configured (all of the WiFi work happens on the ESP module).

Thanks for the library!

For some reason, with this code, the FirmataEventArgs in the callback reports the port as 0.
However, eventArgs.Value.IsSet(2) correctly reports the state of pin 2, and pin 0 clearly does not change, so I am kind of stumped.
Am I doing something wrong?

I am using this wiring diagram, plus an LED on pin 10:

using Solid.Arduino;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using Solid.Arduino.Firmata;

namespace FermataTest
{
    public class Class1
    {
        private ArduinoSession session;

        public Class1()
        {
            var connection = GetConnection();
            session = new ArduinoSession(connection);

            session.SetDigitalPinMode(2, PinMode.DigitalInput);
            session.SetDigitalReportMode(2, true);
            session.SetDigitalPinMode(10, PinMode.DigitalOutput);
            session.DigitalStateReceived += Session_OnDigitalStateReceived;
            Console.ReadLine();
            session.Dispose();
            connection.Dispose();
        }

        private void Session_OnDigitalStateReceived(object sender, FirmataEventArgs<DigitalPortState> eventArgs)
        {
            var isSet = eventArgs.Value.IsSet(2);
            Console.WriteLine($"Digital level of port {eventArgs.Value.Port}: {isSet} (Port 0 = {eventArgs.Value.IsSet(0)})");
            session.SetDigitalPin(10, isSet);
        }

        private static ISerialConnection GetConnection()
        {
            Console.WriteLine("Searching Arduino connection...");
            ISerialConnection connection = EnhancedSerialConnection.Find();

            if (connection == null)
                Console.WriteLine("No connection found. Make shure your Arduino board is attached to a USB port.");
            else
                Console.WriteLine($"Connected to port {connection.PortName} at {connection.BaudRate} baud.");

            return connection;
        }
    }
}

Result:

Hello, I tried your samplecode and during the call of firmata.GetBoardCapability(); I get an OverflowException thrown by WriteMessageByte(int dataByte).
When I change the BufferSize from 512 to 2048 (I went deeper to get somehow narrow it down; for my board, an original Arduino Mega 2560, which has 70 ports to report, the responses-message for GetBoardCapability is 547 Bytes long) in ArduinoSession, the call works. At the Moment I don't want to pull something into Git, because I do my dev on VS 2013 and I'm not sure whether I can without any sideeffects...
So maybe it'S better for someone of the contributors

Hey I'm getting an Arduino soon and I'm pretty much new to the Arduino space, but I was looking for options on .net it seems so far that you have the best-supported library so far even Microsoft doesn't seem to be doing much about Arduino, (Raspberry PI is another story though)

I wanted to see if you are interested in migrating from full .net framework to netstandard2.0
I gave myself a try at doing it on my fork primarily the library and the unit tests project (I did try to update version on the other projects, but no luck so far building the Monitor) and the projects build fine I ran the tests and it seems there are only 7 tests failing from the testing project, I can't get the Integrations test to run

but my guess is that I don't have (yet) an Arduino connected to my PC and that's making the tests fail

I know there's some talk about something similar in #30 perhaps we could coordinate
if you are interested let me know 😁 you can give my fork a test run and see if it's worth the effort

Edit:
Basically it's just removing a bunch of stuff from the *.csproj files here's the commit https://github.com/AngelMunoz/Arduino/commit/503ce689b73a627f2f559d072a11f89ef5019f73
I didn't try to migrate the other two projects to net core since those seem to be desktop gui apps/tests, and not sure exactly what is the exactly process to migrate those kinds of projects.

Despite my best efforts, I cannot get digital inputs or pullups to behave like they should. For instance, on Windows, when I connect an LED anode to a HIGH digital output and the cathode to a digital input, the LED does not light up and the digital input reports it's state with digital state monitor messages. This is the expected behavior since the digital input is not LOW. However, on Ubuntu (Linux loaded onto an old Mac laptop), the LED does light up. Everything is working fine except this one detail. I can receive digital state monitor messages, but they will never show up after the initial board connection and thus digital inputs are non-functional on Linux.

What are the license to the source code?

MIT, GPL, LGPL, Apache lilcense, MPL, BSD

hi thanks for amazing project , am working with stepper motors , so can i control stepper motors with it ? if not how can we add stepper motor support to it

also i checked code of firmdata in the lib : https://github.com/SolidSoils/Arduino/tree/master/Solid.Arduino/Firmata

i not understand in which file have firmdata protocol definitions , as most of the files have get set methods in : https://github.com/SolidSoils/Arduino/tree/master/Solid.Arduino/Firmata

thanks

Hello, i'm trying to use this library in my project, but i cannot do it.

My code:
arduinoSession.SetDigitalPinMode(port.Numeric, Solid.Arduino.Firmata.PinMode.DigitalInput);
arduinoSession.SetDigitalReportMode(port.Numeric, true);

Thread thread = new Thread(() =>
{
bool teste = false;
while(!teste)
{
Console.WriteLine(arduinoSession.GetPinState(port.Numeric).Value.ToString());
}

});

thread.Start();

Always console shows me 0 value.

I am having trouble reading a value on pin A0(14) of an Arduino UNO.
I see a tremendous number of posts with people having the same issues. I feel the SolidSoils library is well written. However, to date, I have not been able to find much information on using the analog side of this library. All responses are vague and without example. There are a multitude of videos and text articles on the digital side. However, the digital side is not my issue, it is intuitive and I have no problem getting it to work. I don't know if multiple analog methods have to be called or in place before checking the state/level of the analog input pin. I have set the pinmodes… what next? The syntax gives only information for that particular method, it does not help if knowing that other methods have to be called or what they are. The tutorials I have found for this library are all digital for C#/C#.NET. Really would like to find a good tutorial on the analog side of the library.

It would be very helpful if someone could provide a short example in C#.NET that reads an analog value from Analog input pin A0 on the Arduino UNO using Firmata. This would be most helpful. The internet and myself would be most grateful.

Hi. I have played around several hours with this library using PowerShell, and I'm able to program digital output to LED connected to differnt pins. But I'm trying to read the analog value from a potmeter connected to an analog pin, and I'm not able to get my head around how this works with the state monitors and the events.
Is there anyone that could help me with an example of running Powershell code for continous reading an analog value from an analog input pin on an Arduino? I just need some code to understand how it is all connected, and then I can work it from there.
It would be highly appriciated

I tried the basic test from the starting page, even though an Arduino nano every was connected, the library could not detect the Arduino Nano Every. The Arduino can be seen by the Arduino IDE and System.IO.Ports.SerialPort.

Please note, that the com port was not blocked by the Arduino IDE because the board was not selected.

Hi im new in c#(Programming in general) but i have a small program to control a led in pin 13 by button in pin 8:

using Solid.Arduino;
using Solid.Arduino.Firmata;
using System;
using System.Windows.Forms;

namespace Arduino_Firmata_Connection
{
    public partial class Client : Form
    {
        public Solid.Arduino.ArduinoSession session = new Solid.Arduino.ArduinoSession(new EnhancedSerialConnection("COM4", SerialBaudRate.Bps_57600));
        public Client()
        {
            InitializeComponent();
            ArduinoConnection();
        }

        public void ArduinoConnection()
        {
            session.SetDigitalPinMode(8, PinMode.InputPullup);
            session.SetDigitalReportMode(8, true);
            session.SetDigitalPinMode(13, PinMode.DigitalOutput);
            session.DigitalStateReceived += Session_OnDigitalStateReceived;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            session.SetDigitalPin(13, true);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            session.SetDigitalPin(13, false);
        }
        private void Session_OnDigitalStateReceived(object sender, FirmataEventArgs<DigitalPortState> eventArgs)
        {
            session.SetDigitalPin(13, true);
        }
    }
}

The button in winforms works but the button connected to arduino doesn't.

Is .NETframework no longger supportted in this project?

Should this code light up my LEDs?

for (int x = 0; x < MAX_ARDUINO_DIGITAL_PIN; x++)
{
firmata.SetDigitalPin(x, state);
}

Upon forking and cloning this repo, when I open in visual studio 2017, I get the following message:

Attached is the upgrade log
UpgradeLog.zip

When app start running, the app cannot communicate with arduino, cannot send message neither receive any message. But when the app still running and arduino is reset manually, the app start to receiving message.

In arduino IDE, when we start serial monitor, this will restart arduino. But this not happen in this case. How do I restart arduino everytime the app is running?

As the title suggests, EnhancedSerialConnection.Find(); results in a timeout error when an Arduino device is connected to one of my ports. If there is no device connected, the connection is null meaning it is indeed picking up the device, but timing out before whatever data exchange occurs can fully take place.

Is there any way for me to disable the timeout of EnhancedSerialConnection.Find();?

EDIT:
The stacktrace shows at Solid.Arduino.ArduinoSession.GetMessageFromQueue(FirmataMessage awaitedMessage)

How i can use Ultrassonic?

The program is working fine on Arduino Mega. I want to run it on ESP8266, but It is not detecting the device. How can I use it on ESP8266?

Hi,

I am working on a quite complex setup with (at least) three Arduino UNO I would like to control them from one PC using FirmataStandard.

Each Arduino has a distinct function in the setup and has to be identified correctly on startup (assigned COM ports may vary between startups).

I can rename the FirmataStandard sketch to something unique and I think I can identify the board by using GetFirmware() and query firmware.Name.

But what is the best approach in general to discover more than one Arduino at startup?

Thanks

Kai

Just to let you know, I'm working on .net core 3.0 support for this library, so I can get firmata to work on a Raspberry Pi.
I've also already added support for custom sysex messages. Still need to make some unit tests for that though.
My fork: https://github.com/jeroenwalter/Arduino/tree/netcore30

Update: it's working, though I have some issues with timeouts while finding the firmata device using the Find() method. Working on a fix....

Anyone else get this unhandled exception when you restart after your program crashes or you terminate it?

It's easy enough to reset the Arduino and restart, but it would be better to handle it in the first place.

ViewModelLocator.cs, Line 32
ServiceLocator.SetLocatorProvider(() => (IServiceLocator)SimpleIoc.Default);

Error	CS0012	The type 'IServiceLocator' is defined in an assembly that is not referenced. You must add a reference to assembly 'Microsoft.Practices.ServiceLocation, Version=1.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.	Solid.Arduino.Monitor	Arduino\Solid.Arduino.Monitor\ViewModel\ViewModelLocator.cs	31	Active

So I add the NuGet package
Then I get another error

Error	CS0104	'ServiceLocator' is an ambiguous reference between 'CommonServiceLocator.ServiceLocator' and 'Microsoft.Practices.ServiceLocation.ServiceLocator'	Solid.Arduino.Monitor	Arduino\Solid.Arduino.Monitor\ViewModel\ViewModelLocator.cs	32	Active

So then I try a different approach.
I discard all changes and reload the project.
In NuGet Packages, I see that there is an update available for CommonServiceLocator. I install the update, but I get the following dialog:

Hello, the same thing is happening to me as reference the problem # 15. This problem was closed without a concrete answer.
I am using an Arduino Leonardo
In my case my computer connects to the arduino, when I put a comment on the line that does the automatic search of the arduino and use, for example, the following change, it works for me.

// ISerialConnection connection = EnhancedSerialConnection.Find ();
ISerialConnection connection = new EnhancedSerialConnection ("COM3", SerialBaudRate.Bps_115200);

I write on pin 13 to make tests and everything goes as it should be.

I have also detected that something similar happens to me in the following parts of the code

var firmware = session.GetFirmware ();

var protocolVersion = session.GetProtocolVersion ();

BoardCapability cap = session.GetBoardCapability ();

I have done a bit of debugging in the code and I have seen that it gives me an exception of type System.IO.IOException

I put the detail of the exception here in case it can be helpful

I have an Arduino sketch that produces about 20 sysex commands per second, each about 30 bytes long.
Writing every single byte to the Debug output has a severe impact on the performance of ArduinoSession. This causes serial data to be queued and processed seconds after they have been received from the Arduino.
I can understand the need to view the raw serial data, but it would be nice if this can conditionally be turned off.
