Thank you for the code. I was able to look at what you had put together and a similar simple code with the only difference being a method of saving the data. However, I find that I am getting about every other sample returned as a zero or some loss of data as seen in the graph below. It is not constant, and it seems that I loose the samples for a period of time and then there is a reconnection. Plotting the data straight from the Arduino-15 serial output with Excell produces a perfect sinusoid from my Function Generator, however looking at my labview plot from the same device, I get an intermittent signal, with no change in hardware.
Thanks very much for any advice.
