The next step would be to review your schematic in order to make sure that everything is connected correctly. Can you share a snapshot of your schematic? I need to see what values you are supplying to the EVM. If you can just describe what/where you are supplying power/signals to the EVM, that would be sufficient.

Unfortunately there is no sample code for this. As far as reference material for the EVM, there is not additional documentation for the EVM but I can get back to you with some scope captures from the EVM.
