Saad Shaikh

• Added third thread to FTDI code to handle file writing, resulting in small improvement to performance.
• Added ability to set test mode and integration time to FTDI code.
  • Integration time set in units of 5us above minimum of 170us to maximum of 1455us (i.e. 170us + 255*5us).
• CTRL-C commands are caught by FTDI code to exit cleanly from DAQ, closing connection with FPGA properly.
• LibFTDI can be installed on Raspberry Pi and can receive data from Nexys Video.
  • Latest version of FTDI code does not work on Pi, likely some compiler issues with "fancier" functions.
  • Will rebuild latest version from older version of code that does work to find problem functions.
• Tested daisy-chain with resistors in place of photodiodes.
  • See the same mirroring whether resistors are in series or in parallel to photodiode.
  • Will reach out to Clive and Izzat to continue discussion.

Fern Pannell

• LibFTDI successfully downloaded and set up on Raspberry Pi.
• Old C++ code compiles, new code throws errors.

High Priority GUI Next Steps:

• Create a standard CSV file with >>16 points for curve data, plot and determine how to keep curve data within the same space as the PD bars.
• Generate links for buttons to add curves to plot that take the user to a new plot with curves overlaid on PD bars.
  • Will need to see whether multiple windows running the JavaScript diminishes CPU performance. If so, terminate old JS when new window opens somehow.

PhD Update:

• Offers for PhD positions with UCL, Imperial and Oxford - Accelerator Physics (PhD Particle Physics).
• Cancelled Birmingham interview.
