Xilinx FPGA & FT2232H used to clock out SPI data & parrelel shift up USB High Speed.
Getting sensor data from a bunch of sensors fast 24 bits per ADC 8 ADCs on one chip 8 chips in the design at 10K samples per second was a difficult problem.
The teensy++ didn't quite do virtual com port over usb that fast and the maple did not.
So I am posting this because it was a interesting engineering puzzle & shows the advantages of the future OAK board with the Xilinx FPGA. The sensors were the ads1298 biopotential mesurement chip by ti. The PC will run blind source seperation to seperate the mixed input signals into its components.
