I figured last night that you have to use the standard firmware (read it somewhere on this forum). So, after downloading the testprogram again, I tried to run it via usb, but I got exact the same error message.
I used this program and in the attachement you can see the imported files in Xamarin Studio
public static void Main (string args)
var ev3 = new Brick<Sensor,Sensor,Sensor,Sensor>(“usb”);
Console.WriteLine(“Error: ” + e.Message”);
Console.WriteLine(“Press any key to end…”);
Also, what is it easier to develop with the custom firmware? Or is it not necessary to use the custom firmware when trying to progam as efficient as possible?
Hope you can help me.
