- Implemented dynamic setting of number of DDC232 boards in UART FPGA design (in addition to USB design).
- FTDI script now starts a new file for measurements after specified refresh rate, rather than after a certain number of measurements.
- WriteCSV however still requires specification of refresh rate to ensure file reader doesn't break – synchronisation is easier now that new files are started after time periods.
- Will investigate performing writeCSV tasks at FTDI level, to improve DAQ rate and synchronisation.
- Added Bragg fit to live DAQ: liveFit reads latest file, averages measurements and then performs fit.
- Took Run 47 from HIT April 2019 dataset as sample Bragg curve and scaled real photodiode data as small amount of noise.
- Typically achieve 2-3Hz with 48 data points (3 DDC232 boards), whether plot is displayed or not. Appears that number of data points is the largest bottleneck.
- Will need to investigate non-ROOT-based fitting procedures to improve fitting rate.
- Did a fresh install of MacOS Big Sur on DAQ MacBook Pro.
- Problems installing MacPorts and ROOT, due to Xcode SDKs. ROOT appears to want 11.0 whereas MacPorts wants 11.2. Latest version of Xcode appears to only provide 11.1!
- Will chase up Texas Instruments about DDC232 daisy-chain problems.
