Connect Software to Hardware
On startup, the software automatically connects to the hardware. On successful initialization, the
software displays a main window, containing controls pertinent to the connected device. If the
software detects an error, an error window appears.
If “Device not found or is unsupported”
appears, verify the correct daughterboard is properly connected to the EVM controller board. If
“Cannot connect to EVM board” appears, verify the USB cable is connected. When the EVM
controller board is connected to the USB, a green LED on the board flashes once on power up to
indicate the USB cable is connected and providing power to the system.
