I am literally started to learn FPGA. I have background on 
microcontrollers. C/C++ is no problem for me. But I am having some 
trouble with FPGA. Actually, not with FPGA but with Compiler and ISE. As 
you can see in the attachment, I configured the FPGA chip. I am using 
BASYS2 board.

This is the implementation code:

---------------------

module myModule(A, B);
    input wire A;
    output wire B;
    assign B = !A;

endmodule

----------------------

And this is the ucf code:

-----------------------

# Onboard LEDs
NET "B" LOC = "M11";

NET "A" LOC = "C11";

------------------------



As board technical sheet says, M11 is LED 1 and C11 is BTN 2. So I want 
LED to flash when I unpress the button. Do you see something wrong with 
the code? Because it aint working. If the code should have been working, 
what should I do? Am I skipping something?

As you see I aldready generated rogramming file. So what next?

Thanks.
