Testing new boards 20180217a
Objective
The objective of this experiment is to test the software issues with the kernel module.
- Series are in the form ZXY where X is the position of the pulser green jumper (on pic below), and Y the yellow jumper, and Z is the series (here A, and B).
- Series A are with the new pulser (macrofab, alt.tbo v2)
- Series B with the old (ChinaCo, alt.tbo v1).
Processing to be done through a jupyter notebook, images stored in a repo, and raw data in another. Pulser code on RPi side is available too where pulses are driven by going low on control pins, and the other pulser code does the opposite.
Images autotagged.
Setup
There is approximately 27mm of water before the reflector on the piezo. That's an echo which has to travel 2x27mm = 54mm, at 1500m/s. We should see at peak at around 36us, and, if a second reflection occurs, at 72us.
Results
Better resolution can be achieved when the pulser code is cleaned from its errors.. Namely with a better control of the controling variables.

Details of the lines
Raw lines
Once filtered
Remaining issues
It seems trig happens when line goes low:
Going low at t0 of pulse
Going low at first up, then down, so delayed
Classical pulses off, Pon going low
