Raffaella Radogna

Saad Shaikh

  • Further investigation of daisy-chain issue in 2nd DDC232 prototype. Still unable to diagnose the problem.
    • Test mode and slowing down DCLK does not help.
    • Unclear if "copying" of data across boards is exact.
    • Added a few slides to last week's presentation.
    • Will attempt shuffling board order to see if that helps.
    • Will organise meeting with Marko.
  • Optimised data transfer from FPGA to PC using FTDI chip.
    • Time taken to send data from FPGA to PC is negligible compared to time taken to shift data from DDC232 to FPGA.
    • Each board in chain adds a 0.494 MB/s requirement to data transfer speed.
    • Will now work on sending data from PC to FPGA over FTDI chip and C++ framework to save data to file.
  • Updating equipment page on DDC232 with information on Nexys Video and new USB interface.
  • Laptop has arrived and is excellent :)
    • When confident that everything on new laptop is working, will do a clean install of Big Sur on DAQ laptop.

  • MSci progress meeting with Jenny Thomas: went very well!
