Stefan Ritt | Increase event rate, use ROI mode, and install sw from source in Mac | The firmware from the website always reads
1024 bins. You have to modify it to stop
before that, like reading only 128 samples |

You see there the rising SRCLK pulse which
outputs the next analog value. You also see |

would be working, you would not be happy
with it. After having designed ~10 boards |
