cfc test equipment (128ch)
we need an equipment for 128 Channel Charge Integrator which can route our current (pA) signal to it one by one.
Contributions: - test equipment develop - fpga program (verilog) - softioc program (python) - hardware design (designed with kicad, manufactured by JLC PCB) - keithley current source control (python) - automatic test program (jupyter notbook) - data processing (python data retrieve, diagram plotting)
- test equipment
-
first version (not my hardware design but I developed its FPGA program. There're so many HW bugs, even relays are all flipped, fixed by hand...🙄)
- second version (basically the same with first version with HW issues fixed but still inconvenient, can only switch channels in order)
-
third version (use raspberry pi SBC with a 128ch io-expander hat, python+softioc inside, easy to use, fully designed by myself)
- keithley current source control (softioc based on pcaspy with phoebus opi)
- diagrams showcase (jupyter notebook)

FPGA downloader
A python program which can be running on raspberry pi or PC. Engineers handle over FPGA flash files (*.mcs) to non-programmers via U-disk, then they can attach JTAG to raspberry pi to perform FPGA flash downloading independently which saves the time of engineers.
