Present

Simon Jolly, Raffaella Radogna, Saad Shaikh, Fern Pannell

Raffaella Radogna

Saad Shaikh

  • Managed to run Nexys Video USB tutorial at around 50 Mb/s.
    • Will start working on implementing USB interface in DDC232 FPGA design.
  • Added functionality to send ASCII commands to set FSR remotely.
    • Will investigate adding some functionality to set different integration times without reconfiguring FPGA.
  • Results from LED tests at UCL show increasing fluctuation/noise with longer integration times and smaller FSR - unsure why this is the case. Also observe 0 values in channels, which should not be possible.
    • Tested integration time of 2000us with 350pC FSR using ILA: confirmed that CONV remains in sync with CLK and could see many 0s being sent on DOUT under low light levels.
    • Could be low light levels with LED.
    • Will continue to test setup at UCL with Raffy.
