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.

Fern Pannell

• MSci progress meeting with Jenny Thomas went very well!
  • Progress meeting presentation.
