Create Arduino based Oscilloscope\GraphPlotter with C# application - Easy!

[@guillaume8437]

Exposed like this, it sounds just so simple! I really need to check it out. I had a project for a long time and never was able to realize it (I am not much of a C# programmer).
Thanks for exposing it.

For big fans of sine waves, just change
for (int x = 0; x0; x--)
{
delay(100);
Serial.println(x);
}
into
for (int x = 0; x

I got a small problem. How can we change the code Line chart1.invoke()... if my x variable in Arduino has Long Int type?

[@swikbymirtahaali]

Arduino sends data to c# application serially in the type of string. You can convert string to long in c# using following code before chart.invoke long lvar = (long)Convert.ToDouble("223.22");
