That's a question for PulseView maintainers. I guess something can be tested right away. I haven't tested this with sigrok. Anyone else? I moved in and haven't had time to get my boards out of the boxes. I'll see if I can test with sigrok with some hardware, maybe this weekend.
Isn't RLE required, as the limitation for continuous sampling for a reasonable sampling speed would be the communication channel?Te quiero mucho tambien
I haven't tried it yet, and I am currently instead using the opportunity to use a Forth system AmForth was chosen the Arduino for a real project: a logic analyser that uses RLE for the transfer of information to the host system, sampling as fast as possible the 4 MHz and sampling at a lower rate but still as fast as possible during the RLE processing and producing output.
On the host side, after data collection of arbitrary length, the data will be converted directly into Sigrok. This allows the device to introduce itself and present the sigrok software with some basic info like number of channels and maximum samplerate, so GUI does not offer impossible samplerates to user.
This means signal goes from right to left. Ending at 0ms timestamp, starting at positive timestamp corresponding to buffer length. Can anyone explain what causes this to me? Also device maximum sample rate is not properly detected.Some time ago I bought chinese version of Saleae Logic Analyzer. Because I mainly use Linux this is small write up mainly for myself how to install Sigrok software for Saleae Logic Analyzer. Story of Saleae is quite common.

Tired of being tied to Windows and proprietary software with limited features, in late he began work on flosslogic, which, after discovering Bert Vermeulen was also working on similar software, became sigrok.

Subscribe at AdafruitDaily.This Arduino oscilloscope is perfect if you need an oscilloscope right nowbut all you have is an Arduino. Check out my new article on how to build an Arduino oscilloscope with 7 lines of code.
I needed an oscilloscope to debug my Radar Arduino library. First of all you need some code to read the analog value from the analog input pin A0.
You can do this easily by using the analogRead function. Then you need to send this value over to your computer using the serial port.
There are plenty of ways to do this. In the following code, the value is sent as two bytes with one 0xff byte in between. This code reads an analog input and writes the value to the serial port. Upload the following code to your Arduino:. This is really all it takes on the Arduino side to make an Arduino oscilloscope. But to display the values, you need some code on you computer too. You need something on your computer to receive the values that are sent from the Arduino, and display them nicely.
Processing is a simple programming environment to do this. Copy and run the following code in processing to get a nice oscilloscope interface on your computer:. You should now be able to use these wires to measure things and see the measurement on your computer. Oscilloscopes are actually very easy to use, once you learn a few basic things: Learn how to use an oscilloscope.
Return to What is Arduino? This is really a very cool way of getting around an oscilloscope, but I was wondering how accurate it is. So if you need precise measurements, this is not the way to go. Cool little project, thanks Oyvind! A few thoughts… One can get good accuracy if rather than sampling from within an indeterminately-sized loop, one instead bases the sample timing on some kind of reliably consistent clock.
Or, for those who really want serious high accuracy, a dedicated real-time clock RTCshould be used. The DS chipcan send clock ticks as fast as kHz over its serial I2C interface, thus your oscilloscope could sample frequencies as high as kHz. Not bad. FFT on the Arduino… what was I thinking? Of course someone has done it!
Maximum amplitude for the ADC is 5V. Thank you for the great project.
I am having some difficulty since I have no idea about processing softwareI have followed all the steps given above but the processing software does not show any wave instead on arduino serial monitor window there are continuous stream of various symbols.Here is a list of currently supported devices various stages of completeness in the latest git version of libsigrok fewer devices might be supported in tarball releases and devices we plan to support in the future.

MyOpenLab is a platform that makes it easy to design virtual interfaces your electronic builds.
If you want controls and readouts for Arduino, Raspberry Pi, Android, or anything with a serial port, this is worth a try. MyOpenLab reminds me of LabView. Not so much modern LabView with all of its add-ons and extras, but LabView back when it did just a few things but did them really well. The open source MyOpenLab project has been around for a while.
The website and documentation are not in English, which may have kept some people from giving it a try, but the software itself is available in German, English, and Spanish. As an example of what you can do, image you want to build a custom bench tool. In myOpenLab your device will consist of two parts: a diagram and a front panel.
Some things only live on the diagram, like a timer or a connection to an Arduino. But some things live on both like switches, LEDs, graphs, and so on. You can connect all the little boxes together to build up applications.
Modern operating systems insulate us — as programmers, especially — from so much work. Depending on how far back you go, programmers had to manage their own fonts, their own allocation space on mass storage, or even their own memory allotments. Every year, though, it seems like things get easier and easier. So why is it so annoying to open a simple serial port? And it is even worse if you want portability.
What I wound up with the serial library from Sigrok. You know Sigrok? The logic analyzer software. You might counter that the serial port is old hat, so no one wants to support it with modern systems.
I guess the Sigrok developers had the same problem I did and they took the time to write a nice API and port it to major platforms.
Although Sigrok uses it, they maintain it as a separate project and it was just what I needed. Sort of.
I say sort of because the version installed with Ubuntu was old and I needed some features on the newest release, but — as usual — the Internet came to the rescue. A quick Git command, and four lines of build instructions and we were ready to go.
If you think of a medical x-ray, it is likely that you are imagining a photographic plate as its imaging device. As with the rest of photography, the science of x-ray imaging has benefited from digital technology, and it is now well established that your hospital x-ray is likely to be captured by an electronic imaging device.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Have you considered trying to add Sigrok compatibility to your Arduino scope? I think you could go one of two ways. Either add support for a new instrument to Sigrok, or make your Arduino behave like an existing device on the serial interface. Skip to content.

Sign up. New issue. Jump to bottom. Copy link Quote reply. Hi, Have you considered trying to add Sigrok compatibility to your Arduino scope? Hi Peter, Yes I came across sigrok when I was looking at the possibility of doing a logic analyser with the same hardware. I have downloaded it onto my Mac and I will try it out soon with my scope once this month's project has been submitted. However, the thing I don't know how to do is what software I would need to add to the Arduino to make it look like an instrument, but I haven't looked into it yet.
I might end up using a faster Arduino I don't know yet. Anyway thanks for the interest and suggestions. Cheers Mike. Sign up for free to join this conversation on GitHub. Already have an account?
