I purchased the ADRF6518 Evaluation Board and am having some problems. I installed the software from Analog on the webpage for the ADRF6518 and I believe that I got the drivers installed correctly, yet I am not positive because I cannot think of why else this would not be working. The software loads only when the board is plugged into the computer USB, so I know some sort of communication is going on. Yet when I try to change the parameters of the device, such as the gains or the corner frequency and click on the write button, nothing happens. The display boxes that show what is set on the board do not change. I have tried this on my Macbook, using Parallel Desktop that runs a 32-bit Windows 7 OS. If i change one of the numbers in the display boxes that show what the board is set to and press read or write, the number refreshes to its default value. I was trying to set up the software on a 64-bit Windows 7 laptop but it would give an error when trying to install the driver, even though the program would still come up, but had the same issue.
