- Further bug fixes and work on USB interface: now able to dynamically set number of DDC232 modules remotely.
- Will update UART FPGA code to also allow setting number of DDC232 modules remotely.
- Further work on DAQ framework:
- DAQ script sets full-scale range and number of DDC232 boards and then saves X number of measurements per file.
- Trade-off between DAQ rate and refresh rate of display: averaging/plotting scripts can only access closed files and best DAQ rate is achieved by saving data to single file without closing. Reading more boards also slows down DAQ.
- WriteCSV waits for a new file to appear, averages all measurements in the file and then updates a single-line CSV file at 50Hz.
- Local live plot reads last line in each new file to plot. No averaging in order to reduce latency between DAQ.
- Features to implement:
- Replace number of measurements per file with a time spent on each file, in order to lock-in the rate at which new files appear.
- At FTDI level, scale photodiode data and add real Bragg curve. Add fitting routine to writeCSV or update liveFit to perform averaging and fitting.
