* Please make sure that libm2k-sharp.dll and libm2k-sharp-cxx-wrap.dll are in your build folder.
* Please make sure that the location of libm2k is in the PATH.
*
* This example assumes the following connections:
* W1 -> 1+
* W2 -> 2+
* GND -> 1-
* GND -> 2-
*
* The application will generate a sine and triangular wave on W1 and W2. The signal is fed back into the analog input
* and the voltage values are displayed on the screen
