Changes

1. Build the bitstream (or see the pre-built one in the repo)

2. Use settings as in the 'Default XMEGA' or 'STM32Fx' targets (i.e., clock jumpers, etc).

3. Ensure you have turned on the 1.8V & 3.3V power supplies to the UFO target.

4. Program the bitstream into the FPGA using a programming tool.

5. Run the 'XMEGA Simple-Serial' script in ChipWhisperer-Capture. This will setup clocks, serial data format, etc as expected.

6. Adjust the trigger offset settings - they should be changed to around ~750, and you can reduce the number of data points to ~128.
