I finally got this finished and low and behold, the trackball is not functioning. I have double checked all wiring, and am geting a strong +5v to both optic boards. I have tried connecting to the solder side as directed and to both pin connectors on the board, as well as changing the settings appropriately. Nothing has worked. I have attached a pic of the test screen, and all of the I/O checks stay red all the time. Is there a setting I am not aware of, or is there something else I am missing? Any assistance would be appreciated. Thanks.
