The bit file provided in the project *.zip file combines the FPGA bit file and the SDK elf files. It may be used for a quick check on the system.

To begin, connect the PmodGYRO2 to J5 connector of LX9 board, pins 7 to 12. You must use an extension cable or the Pmod-TPH (Digilent). Afterwards connect PmodACL to connector J4 of the LX9 Board (see image below).
Start IMPACT, and double click “Boundary Scan”. Right click and select Initialize Chain. The program should recognize the Spartan 6 device (see screenshot below). Program the FPGA using the download.bit file provided in the project *.zip archive, located in the “sw” folder (../adxrs453_adxl345/sw/download.bit).
Start a Hyperterminal program (Tera Term, puTTy, etc.), select the proper COM Port (look for the COM Port named Silicon Labs CP210x USB to UART Bridge in Windows Device Manager). Select 57600 Baud Rate and Odd Parity. You should start seeing messeges in the Terminal Window, displayed on 4 columns, representing the rotation of the board in Degrees per Second, and the acceleration in g on each axis.
On the LX-9 MicroBoard D10 and D9 display the Tap/Double Tap status. If you tap the device once, D10 will turn on for a short period of time. If you double tap the device, D10 and D9 will both turn on at the same time.
