Read out Hamamatsu S17285 with NI-DAQ
- Install LabView on PBT Intel MacBook Pro.
- Set up NI-DAQ USB6366 to output test patterns on selected pins:
- Write custom VI to output chosen frequency test patterns (different on each pin).
- Test output with scope.
- Replicate Saad's DDC232 slides with detailed signals for communicating with S17285.
- Communicate with S17285 with NI-DAQ...

Replicate Raspberry Pi/USB104 readout with Kria and IC KriaDAQ board
- Implement USB-C cable tester using IC KriaDAQ:
- Output test signals from single USB-C port (FW only?): Andy Rose/Matt Warren/Erdem Motuk.
- Test signals for each channel with different frequency.
- Use LVDS pairs for 5 differential pairs; check existing firmware for single-ended signals.
- Measure output with scope.
- Set up IPBus communication between PS and PL: talk to David Sankey.
- Read output with second USB-C connection.
- Collect output and "display" with PS.
- Migrate USB104 firmware and FTDI C++ code to Kria:
- Connect DDC board via USB-C: check for power!
- Send configuration and read back test pattern.
- Adapt buffer for Kria hardware: Andy Rose/Matt Warren.
- Read back live photodiode output from DDC board.
- Read back live photodiode output from 4 DDC boards.
- Extend readout to multiple KriaDAQ USB-C connectors.
- Single board each on 2 connectors.
- 4 boards each on 2 connectors.
- Extend to 5 USB-C connectors.
- Control readout with web GUI.
Design and Implement firmware for SciFi readout

Power supply board
Ready for experimental visit to Trento, 28th September 2025
- Power distribution board required for QuARC.
- Provide power for Raspberry Pi and DDC boards from single DC input:
- 5V/5A for Raspberry Pi via USB-C
- >7.5V (5A?) for DDC board daisy chain via 2.5mm barrel
- Single USB-C PD input: 20V/5A
- Needs USB-C PD voltage negotiation chip
- Fallback option with 20V DC 2.5mm barrel jack input
- LEDs to indicate each voltage is provided correctly:
- 20V input
- 5V to Raspberry Pi
- >7.5V to DDC boards
- Should be able to switch off LEDs
- Necessary to switch between input power supplies?
- Ensure both power outputs stable: no drop-outs!
- Potential for USB-C PD to drop out when voltage renegotiated?
DDC Photodiode Board Rev.G
Upon completion of power distribution board
- Return Rev.F boards and ZMOD boards to be fixed: ✓
- Remove RESET connection from CC2 pin on all DDC board USB-C connections
- Resize DDC board to accept Hamamatsu S12362 16-element photodiode array in place of Hamamatsu S12915-16R single photodiodes
- Reduces pitch from 3mm to 2.5mm
- 2 photodiode arrays per DDC board (2 x 16 element arrays = 32 channels)
Scintillating Fibre Profile Monitor Front-end Boards
Upon completion of Rev.F board
- Integration of scintillating fibre profile monitor based on design from Blake Leverington, University of Heidelberg
- Hamamatsu S17285 photodiode arrays to couple to scintillating fibres
- Interface board needed between USB-C connection from FPGA and photodiode arrays
- Acquire data; distribute timing signals
Imperial
QuADProBe FPGA Upgrade
- QuADProBe QAD to be upgraded from USB104+Raspberry Pi to Kria:
- Kria available off-the-shelf but carrier board needed
- Imperial to design carrier board with multiple I/O for QuADProBe:
