Raffaella Radogna, Saad Shaikh, Fern Pannell

Tested daisy-chaining 2nd DDC232 board prototype, discussed results in this presentation.
- Daisy-chain works with 2 boards but not 3 or 4. Observe strange correlation/mirroring of readings across 2nd and 3rd boards in the chain. Unclear why this occurs but determined that this is a circuit board issue rather than FPGA/PC issue.
- Will test daisy-chain with slower DCLK and in test mode to see if situation improves. Will also saturate photodiodes one-by-one to better understand which channels are "linked".
- Will likely need to contact Texas Instruments to ask why this might occur before discussing with Marko.
Debugged USB interface – now correctly sends data.
- Need to optimise speed further: FPGA write timing and C++ read timing. Latter will be more important.
Laptop should arrive at UCL this week! :)

GUI currently functional in Chart.js operating at 10Hz.
Tested with Saad and live photodiode data, minimal delay between light exposure adjustment and change in web plot.
Delivered summary presentation in preparation for progress report write-up.
