I purchased the ADNS 3080 and have connected it exactly as is shown in the setup guide. I have flashed the test hex file, but all I see for output is zeros, both in the terminal and with the python script.
When the terminal first opens the test program I see "Failed to initialise ADNS3080". I'm not sure what else to try. I've triple checked the wiring. Has anyone had success with this sensor recently?
