No promises yet but I might be able to publish a data decoder for the #hp1652b logic analyzer somewhere tonight together with a (incoherent) blog post.

This decoder is written in Python as opposed to the eventual #Sigrok driver.

#hp1653b

Registering a new driver with libsigrok #sigrok seems easy enough

I started making a clone of "Logic2" (a commercial logic analyzer software) based on libsigrok and GTK4.

This is an experiment and merely a reason to learn GTK4.

It's not really functional yet.

Sigrok Website Down After Hosting Data Loss

When it comes to open source signal analysis software for logic analyzers and many other sensors, Sigrok is pretty much the only game in town. Unfortunately after an issue with the server hosting, the website, wiki, and other documentation is down until a new hosting provider is found and the site migrated. This leaves just the downloads active, as well as the IRC channel (#sigrok) over at Libera.chat.

This is not the first time that the Sigrok site has gone down, but this time it seems that it’s more final. Although it seems a new server will be set up over the coming days, this will do little to assuage those who have been ringing the alarm bells about the Sigrok project. Currently access to documentation is unavailable, except via the WaybackMachine’s archive.

A tragic reality of FOSS projects is that they are not immortal, with them requiring constant time, money and effort to keep servers running and software maintained. This might be a good point for those who have a stake in Sigrok to consider what the project means to them, and what it might mean if it were to shutdown.

Как подключить мультиметр к компьютеру

Периодически возникает задача снимать показания мультиметра через определённые интервалы времени и записывать их в файл. Например график напряжения при разряде или заряде аккумулятора. Вообще для этого есть мультиметры с функцией регистрации данных, но ни один, из имеющихся у меня, не обладает таким функционалом. В бюджетных мультиметрах ZT102 и ZT301, которые построены на чипе DTM0660, можно реализовать подключение к компьютеру, но для этого придётся редактировать EEPROM и вносить изменения на печатную плату. Это несложно и Kerry Wong описывал как это сделать на примере мультиметра ennoLogic eM860T. В тоже время у моего настольного мультиметра Agilent U3402A на задней панели уже есть порт RS232, но на нём указано "используется только для калибровки". Аналогичное предупреждение есть и в инструкции пользователя на русском и английских языках.

Habt ihr einen #Sigrok-kompatiblen Logic-Analyzer (gern auch mit Display und/oder analogen Messungen) für unter ca. 100 €, den ihr _richtig_ geil findet und mit dem ihr super glücklich seid?

Ich brauch (noch) nichts super abgefahrenes, und mir ist bewusst dass ich für nen Zehner nen China-Analyzer bekomme der wahrscheinlich für alles taugt was ich brauche. Aber vielleicht gibt's ja ein Wohlfühlgerät.

Wenn standalone betreibbar wären FLOSS-Firmware bzw. eigene Decoder hilfreich.

I'm trying to bodge in a custom device into libsigrok. Unfortunately, I'm having no luck as the driver doesn't show up in the device list even though I'm using the recommended driver skeleton. #sigrok

Okay, I know how to reverse engineer the WS2812 protocol that WLED speaks to an RGB LED strip with my logic analyzer. But all I get is color codes. Where are the command or addressing parts? How can I find those in an acquisition? Still learning „how to logic analyze“. Ben Eater to the rescue! 😂 #electronics #ws2812 #wled #logicanalyzer #esp32 #sigrok #pulseview #BenEater

Im Home-Lab nutze ich unter anderem ein #RD6018 für gewisse Versuche. Vor längerer Zeit hatte ich ein #Bluetooth-Modul eingebaut, um es mit #sigrok fernsteuern zu können.

Besonders bei Spaghettiaufbauten, wo man an Strom/Spannung drehen und parallel auch noch Sachen in der Restbussimulation herumändern muss, bin ich über diese drahtlose Fernsteuerbarkeit jedes mal froh und glücklich.

Sometimes open source guys are real a**holes really. I report a problem on #sigrok IRC, and I'm told that I should try to run a random manufacturer binary app on my linux system, and if I don't, well, sod off really.

Hmm a bit further with #sigrok but hmm; I've figured out it's 3 modes; 'live' is quite quick but gets the limited samples that I was seeing. 'memory' grabs the whole buffer - which on my Rigol over ether takes ages; and 'segmented' which is like memory but grabs it in chunks so you can start exploring while it downloads. Those get me full sample rate data - unfortunately their is something screwy going on with the concept of time so the USB decoder is completely confused in those modes.

Playing with sigrok, its decoders and Pulseview.
#sigrok #cctalk

Black friday at TME finally forced me to buy my first oscilloscope (and many more things). Real struggle was to figure out if I want USB one or desktop one. After checking all kinds of decoders which sigrok supports, I decided to go with USB one and hoped for best.
I'm still a little confused but it seems to work under certain conditions. Many thanks to people making sigrok!

I'm curious. How many folks would be interested in using the Analog Discovery 2 with Sigrok? I know there was an old attempt at writing a driver for the original Analog Discovery but it was never finished. I however have the AD2 and would prefer to use FLOSS when using my tools, so I might take a crack at figuring out how it works. #analogdiscovery2 #digilent #sigrok
