Re: Saving 576 plots (again)


 

This is my point exactly about feature creep on these threads, haha

Guys, it really shouldn't be that hard. As a little proof of concept yesterday (the post hadn't been approved yet and I was itchy to find a solution) I rigged up the worlds simplest curve digitiser with a super basic transistor curve tracer I got at an estate sale a while back (my 576 still hasn't arrived).

Literally all I did was add a 1 ohm sense resistor to the emitter connection and then probed across that for current and the collector for voltage into a DSO. Saved as CSV and opened as a graph without issue, looked exactly like the trace on the screen at the time and included scale. Tried the same thing with a current probe instead of a sense resistor, result looked just as good. You can take these basic ideas and optimise them a thousand ways from there, but to be honest the results were good enough that I didn't see much point digging any deeper because I had clean curves saved for later recall, which was the goal.

Based on that I ordered one of those little ICP12 boards I'd heard about on here, if it produces reasonable results I'll just stick one in each text fixture I make with a few resistors to scale voltage etc and the problem should be solved.
