The first time using #ngscopeclient actually to debug things.
The two screenshots are SPI-measurements with 2 different firmwares on a custom STM32H743 board
The left PoC and the right is the final Firmware.
Obviously I checked the board definitions for pin configuration differences, but I couldn't find anything obvious.
I cannot wrap my head around how the CS-Voltage (Blue line) differes on these 2 firmwares. It almost seems like there is some kind of capacitance on this line judging by it slowly ramping up and staying below the 2.1V threshold to be recognized by the DAC.
The 2nd firmware has a lot more peripherals going including Ethernet.
I don't think it could be brownout as any other line seems stable...
Of course that CS-Line is bodge-wire from the MCU-pin to the DAC-Pin, but in my head that would affect both firmwares if this was the case, right?
Thanks @azonenberg for building this awesome tool. -
🎉 New video showing off running PCI express over COTS SFP modules and associated complications along with future plans.
And then a small side quest involving optical splitters and #ngscopeclient
Definitely on the long side, sorry about that 😬 But I hope it's still interesting 🤞

Continuing in the process of measuring the speed of my turntable in the oddest way; here is the FFT before and after oiling & replacing it's belt. Hmm, it's clearly a bit fast before and a bit slow after; it's not got any speed adjustment mechanism, it's a belt on an AC driven motor.
This FFT and plot was done using #labplot using the waveforms gathered by #ngscopeclient and saved via csv.
This is of course the wrong way to solve this problme. -

if you use or contribute to #ngscopeclient: I will pay £150 to anyone who adds MHO98 support; I can provide access to a live scope to that end

And another first test: One instance of #ngscopeclient running with a PicoScope 4824 and a PicoScope 5444, eating each other's signal generator output.
Most important work is done; now on to some polishing and wiping out more bugs.

First test running the signal generator on a PicoScope 5000 using #ngscopeclient. Funny thing that the AWG is set to off 🤔...

Getting somewhere... ''first light'' with a #PicoScope from the 5000D-series running in #ngscopeclient 💪! Still a lot of stuff to check and implement, but I'll get that done eventually.

Modified #ngscopeclient to support colors per stream. Now I can plot my embedded thread utilization data and explore it blazingly fast.

@azonenberg has anyone tried to add 1990s #Tektronix scope (e.g. TDS744) support to #ngscopeclient ?
I just got one and am wondering if there is no support due to limitations of the scopes or just because nobody botheted to add support yet.

I don't know if this is useful for anyone else, but I just built ngscopeclient for Windows, and thought I'd share the packages. (It was a lot less painful than last time I tried, even if the VM kept running out of RAM! 😀)

I'm in the market for a small, reasonably priced and reasonably powerful #oscilloscope for home use. #ngscopeclient support would be a definite plus but not a hard requirement. Being able to run from USB-C and/or built-in battery is a requirement.
It seems the Miniware DS213 is still the state of the art here, but it seems to run via micro-USB which is just annoying. Any others I should consider?
