Hi Stefan
Thanks for your input.
We are in the process of assemble another PCB board. |

Hi
We have resolve the problem, the Dtap is now working correctly.
There were two problems: |

surrey i forgot to update..
after carefully examining our VHDL we found out that there are brief times that we put A0-A3 in 1111
after making shore that a0-a3 never get 1111 value thae drs4 woks as expected. |

hello i am an student and i want to do my final project with drs4 board and i really can´t find how to open waveform file and how can i save or
opened many of them quickly.
if you can tell me how i will be very grateful. |

I am having a general problem getting read back using the ROI mode. In the transparent mode everything looks good. These are the steps that I take:
1) configure register (b"11111111",addr = "1100")
2) configure write shift register (b"11111111", addr = "1101") |

Thanks for replying Stefan.
I was more so just concerned with the steps in the firmware when I had asked. However, yes the ROFS (1.05V) and O-OFS (0.9 V was 1.3 V earlier
but, changed this becasue of ADC input requirements) are per spec, the VDD voltages are all there and input voltages are within the rails and finally the |

Hello, everyone.
I'm a student in Japan.
Please forgive me if this is a very rudimentary question. |

Dear Stefan
Thanks a lot.
I solved it. |

Hallo,
I'm using DRS4 Evaluation Board Rev 4.0 and I'm trying to change the output of the samples to be an average of # measurements (1000
or even more) |

Hi Stefan,
According to the datasheet DRS_rev09, the write signal is always 16 cells wide. So when the domino wave runs in infinite mode and be stopped
by setting DENABLE low , there are always 16 cells capicitors tracking the input signal . It means that the effective sample cells is 1024-16=1008? That's |
