  • 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.
