Hi Jacek,

thanks, looking forward to use this!
But I really don’t know what to do, I’m not a a professional programmer..

Could you tell me how to compile the firmwarelib from the master branch and use your solution?

I’m using Visual Studio 2012 C# with Windows 7

Hi everybody,

I’m a litte bit confused.. the new EV3 Colorsensor is not able to read RGB ? Why would LEGO do that?
I’ve tried this Code out of the new Tutorial from Max Mustermann, but with the EV3 Sensor it doesn’t work.
Red 0
Green 0
Blue 0
all the time.

using System;
using System.Threading;
using MonoBrickFirmware.Sensors;
using MonoBrickFirmware.Movement;
using MonoBrickFirmware.Display;
using MonoBrickFirmware.UserInput;

namespace farbsensor
{
    class farbsensor
    {
        static void Main(string[] args)
        {
            EV3ColorSensor farbsens = new EV3ColorSensor(SensorPort.In1);
            
            bool abfrage = true;
            string rotwert, gruenwert, blauwert;

            RGBColor RGBFarben = new RGBColor(0, 0, 0);
            ButtonEvents buts = new ButtonEvents();

            buts.EscapePressed += () => 
            { abfrage = false; };

            while (abfrage == true)
            {
                rotwert = Convert.ToString(RGBFarben.Red);
                LcdConsole.WriteLine("Rot :" + rotwert);

                gruenwert = Convert.ToString(RGBFarben.Green);
                LcdConsole.WriteLine("Gruen :" + gruenwert);

                blauwert = Convert.ToString(RGBFarben.Blue);
                LcdConsole.WriteLine("Blau :" + blauwert);
                Thread.Sleep(2000);
            }
            LcdConsole.WriteLine("###############");
            LcdConsole.WriteLine("PROGRAMMENDE...");
            Thread.Sleep(3000);

        }
    }
}

#EDIT
I forgot
RGBFarben = farbsens.ReadRGBColor();
infront of the “while-loop”, but farbsens does not have the function ReadRGBColor(), how can i do it?

Hello Jacek,

could you please tell me how to detect orange with your solution ?
I’m using a EV3 Colorsensor.

I’ve tried a bit with the code you have posted and checked the library page

but i don’t know how to write the code properly.

Is there no option to send private messages in this forum?

Well:

Maybe a chapter about all these WaitHandle commands…
you need these a lot if you work with

motorA.SetSpeedProfile(speed, degrees accelerate, degrees hold speed, degrees brake, break at end?(true/false));

Otherwise it won’t work fine. I’ve started a thread about that two weeks ago.

And I need to know how to detect Orange with the EV3 Colorsensor^^

[Auctor137]

Awesome
I’m from germany and that’s really helpful – really appreciate that!

already printed it ;D

[Auctor137]

Yeah I know, but i need to read the colors. I’ve used the EV3 Colorsensor now and it works fine.

[Auctor137]

…

I’ve used the NXT LIGHTsensor, not the COLORsensor.
Oh man.

[Auctor137]

Thanks a lot Anders, your code works great.
I’ve modified it a bit, to do only 8 turns (=360degrees).

and I’ve started another Thread about the nxt color sensor.
