Saad Shaikh

• Tested DDC232 daisy-chain with resistors, experimental runs listed here.
  • Will send another email to Clive and Izzat to ask for help.
  • Raffy to get in touch with Marko to get a quote on new DDC232 boards made.
• Added new details to the DDC232 page, with latest version of FTDI code.
• FTDI code works on Raspberry Pi, with only a few changes to compile command.
  • ftdi_tcioflush function not found, but older deprecated version can be used instead.
  • Pi is slow, with average time between measurements at about 650us instead of 180us.
  • Will benchmark performance of "minimal" version of FTDI code, where data is collected but not processed.
  • Will also benchmark performance of "full" and "minimal" versions of FTDI code on Windows.
• Will compare channel noise of single DDC232 board with alternate photodiodes replaced with resistors.
• Will start investigating non-ROOT-based fit.
  • Raffy has suggested to use GNU scientific library.
• Working on HEP School problems this week.
