The 30-pin connector on the driver board?
That's just a 2x15 pin header, but with a 2.00mm pitch.
IIRC
So a fair bit smaller than a 2.54mm (0.1'' pitch) pin header.
There are some Pi o'scope projects I believe, yep. I have no idea if they are any good.
Some might be using some slow ADCs which have very low bandwidth, so not super useful.
I've also wanted for years to design my own o'scope.
I think I could handle most of the GUI stuff. The main challenge is the analog frontend, and finding decent ADCs that don't cost too much.
A lot of o'scopes also tend to use LVDS (or at least some form of differential) output from the ADCs to the FPGA/ASIC, so that gets a bit more tricky to do.
(one problem is, ''LVDS'' is really just the voltage-level and differential standard. But ''LVDS'' on LCDs is it's own protocol as well.)
I'm always very wary of projects like this, which don't make it immediately obvious what the SPECS are. lol
BitScope
Raspberry Pi Oscilloscope | Test, Measurement and Data Acq...
Programmable USB and Ethernet oscilloscopes, logic analyzers, generators and data acquisition for Raspberry Pi.
It's like when browsing for an electronics gadget, but they don't give the damned PRICE. Literally the most important metric is price vs performance.
Oh, fair enough, it was on one of the first hyperlinks.
BitScope
Micro Model 5 | A tiny USB Mixed Signal Oscilloscope
A tiny programmable dual channel real-time mixed signal USB oscilloscope and 8 channel logic analyzer for Linux, Windows and Mac OS/X.
20 MHz bandwidth isn't too bad. It's good enough for helping diagnose older retro consoles, for example.
But beware that most o'scopes consider that you need a sampling rate of around 5 times (or more) of the bandwidth.
40 Msps isn't really enough to get good captures at the full 20 MHz, AFAIK.
(if you're looking at say a 20 MHz clock signal, it's gonna start to alias and show weird stuff on the o'scope.)
What I REALLY want, is a good Logic Analyzer with plenty of channels.
This is by far the best I've seen... CoLA
But I think they used a 6-layer board, which gets expensive even on JLC.
And now, of course, the Cyclone V chips are hard to get hold of.
But up to 96 Channels capture, and streaming USB 3.0 direct to the PC. That's a lot.
I designed one very shortly before I saw the CoLA thing. Typical. lol
