JAVA problem possible solution: I had today a lot of errors on CMD with v0.8 while v0.7 worked. Now v0.8 works as well. I hope this will be helpful for others: 1. Did an update on my graphics drivers (Laptop with AMD and Nvidia RTX2060); used Nvidia Studio drivers with the "new install" option hoping that it would clean up the old drivers. 2. Used "Eclipse Temurin Java SDK 16 from Hotspot" (v17 does not allow the "illegal-access=permit" flag, and others reported success with v16) 3. started with in CMD with the command: java --illegal-access=permit -jar TelemetryViewer_v0.8.jar Not sure which of the first two points did it, but with 8 months old drivers and different other JREs it did not work, even with the "illegal" flag. Hope this helps. Thanky you for the great app!!!
Thanks alot for this great tool. I just got startet with Arduino and it was surprisingly hard to find a solution to visualize sensor data in realtime. This works great.
Thank you for your "real time" visualisation tools for a data driven world. I am a research student who is working on comparing real time domain system performance data. I used your java dash (done 5years ago) but could not get it to work. For some reason I get all the controls but not the graphing area. I used the JDK link you provided and checked opengl functions.

This is epic. I've built a teensy based can bus datalogger for my car and I have managed to write to SD card with a generated sample number, UNIX timestamp converted from onboard RTC and 75 data inputs from the vehicle. The only thing I'm struggling with is the Arduino ide SD library will only save filenames with an all capitals ".CSV" The only workaround I have found is to save the csv files as .txt and renaming the files as ".csv" when I open them on the computer. If there is a way to allow it to let the software open ".CSV" file extensions it would be amazing. Also is there a way to incorporate a chart that is a stack of horizontal bar graphs to see multiple parameters at a glance like your dials but in a more vertically compact format. I came across this series only a few weeks ago, love your work and keep the updates coming!! Thank you
Thanks a lot for all the effort you put into this amazing piece of software! I have a question though: Depending on the transmission, the data might arrive with a certain (non-constant) delay. To account for this, it would be great if there was a possibility to assign a "timestamp" sent by the microcontroller (or any other source) to the x-axis of the plots. Is there any way to achieve this? As far as I understand, right now the x-axis corresponds simply to the time of arriaval of the message. Thanks for your reply :-)

Hello Farrell, three things: First of all thank you very much for sharing your excellent work, you must know it is being used to develop new things and teach my strudents about instrumentation , second: is there a way to input keyboard commands or keyboard combinations to control the software? we are trying to automate some things like exporting data after a certain time. Third: We are connecting more than ome serial arduino based sensors, and it is very important how syncronized we get the data, at the time with two serial sensors I have seen more than 200 ms, can you comment about it?, thanks in advance for your response
At the moment there is no support for keyboard shortcuts. As for synchronized data, Telemetry Viewer has no control over that. Your devices send telemetry packets whenever they choose to, the PC simply listens for incoming data. If you need multiple devices to send data in sync, you will need to design some external way for them to stay in sync.
First up - this software is awesome! (Apologies for using the comments section as a help forum). I've got the basics, but now I'm trying to parse some CSV data coming over the serial port. Is there a limit to the 'length' or size of data in each column? For instance, I am unable to parse some data: "RD,-230.977,00000000,00000000,-052.252,1940" (I get a corrupted data error) whereas, this: "00, -231,0, 0,0, 0,0, -54,0" parses just fine. The data is essentially the same, aside from the fact that the first string always starts with letters "RD", and the second string has a '0' colum after each data value.
Thanks. The length of that line should be fine. The "RD" part is most likely the problem. Telemetry Viewer assumes the text will contain only numbers separated by commas.
Awesome presentation and I was wondering if I could apply it to my situation. I have an Arduino in a remote location with 5x temperature probes. I currently have web access to see the temperatures. Is it possible to use your solution via a TCP/IP interface to a remote computer to display graphs and values?
You would probably need to write a little program that reads from the web interface you have, and generates TCP or UDP packets formatted in the way TelemetryViewer can process. You could then transmit those packets to localhost (or wherever TelemetryViewer is running.)
Is there any way to use a different 3D model instead of the embedded monkey.stl I I tried replacing the monkey.stl in the resource directory but not a Java programmer I don't know how to recreate the JAR file with the new graphics. I tried sending you an email about an opportunity.
Hello! I love this app, it's super useful. Any chance you could add so that you can send a struct from the arduino with the sensor data inside? You send it as a struct with serial.write with a pointer to the struct and the size of the struct. That way I can send many, many more values before the loop starts to slow down. Sending 5 floats with comma separated starts slowing things down while I've only tried up to 10 floats with the struct and it's not showing any signs of slowing. Thanks.
Hi, there you are doing a great job. I have used your v6.0 version and it works fine for single UART and UDP. But now I need multiple com port readings from 2 ESP8266, and I am using version 8.0, but I am facing problem regarding connectivity. Previously ESPwifi libraries are used for connectivity but here in v8.0 "esp8266_join_ap" function is used which doesn't use the WiFi.udp connection and hence does not connect to the hotspot. Have you used esp8266 with Telemetry v8.0?
I appreciate you putting together once again. I am having trouble with placing a window for data sets now since the update. Do I need to roll back the Java version or am I missing something? It connects and the CSV is transmitting to the serial monitor from my Mega. What am I doing wrong?
Hi. The latest version of Telemetry Viewer uses some features that were added in Java 9. If you Upgrade to Java 9 or newer it should work correctly. If you use Java 16 there is a special flag needed to make things work. See my web site for details.
Hello there. Great software. I am trying to use Telemetry Viewer 8.0. with my STM32 board but all I see is a white screen at the connection screen. How can it be solved? Thank you.

I probably misunderstood the Arduino serial interface to Telemetry viewer v0.8 or did anything stupid in my setup, but I must ask. I have Arduino IDE 1.8.19 with an FTDI adapter sending analog data read from port A0 on Arduino Uno to serial port /dev/ttyUSB1 (also seen on putty as "214,132,211, ...,") . I have connected at the correct baud rate of 115200 Baud, but the Telemetry viewer waits forever for "[...waiting for at least one CSV column...]". I have also tried with println() and other CR/LF combinations, I see an endless comma separated numbers sent to the serial monitor, but I still can't figure out how this suppose to work. Please help. Cheers.
Have you defined your data structure? You need to tell Telemetry Viewer about each column. "Waiting for at least one CSV column" means that no columns have been defined.
Hi there! I'm following since your first steps with the robot, and I love it! But the most impressive thing is how you manage the data. And I would like to contact you to talk about a project that you will love. Regards, Luis, ;)
Wow, this is amazing. I've been using the older versions a lot. Is it possible to send only a few data samples at a time with this new version? When I need to read 10 sensors I start two sensor readings then do some calculations on the previous two sensor readings and so I don't have to wait for the reads to finish before doing processing. Right now I have to wait for all sensor readings to finish before sending all 10 as serial prints. This slows down the sensor reading speed because sending 10 values at once takes time. It would be a lot more efficient if I could send two at a time in between the sensor readings and then have telemetry viewer combine them into 10 separate sensors. This would be much faster and I could read all 10 sensors in 20 microseconds.
@@upgrdman maybe make a buffer that waits for the slots to fill. I wish I was skilled at programming so I could modify it my self. Anyway, I really appreciate your efforts.
Hi, nice work, appreciate it, I try to study how you build the software, watch all previous videos, I have tried all the jar file revision, version 0.7 works okey, but when I try version 0.8 giving me error when i started, Error is "unable to create cache file for"cache\storage floats@13b9586.bin", installed in windows 10, any solution on this?
That means the OS wouldn't allow the file to be created. Make sure you're current working directory is a place where your user has permission to create files.
Hi, I manage to make it work, creating Cache Directory in the installed directory and using Java 9 SE runtime downloaded from Oracle website (create an account), timeline function is very useful when logging several hours, I will continue my project development now, thanks for the help, good work

But the data does not appear on the TelemetryViewer no matter what I do. Any suggestion would be extremely helpful. I am running Windows 8.1 on my laptop.
Try using a tool like Wireshark to verify if those packets are actually getting to your laptop, and to also verify that the contents of those packets are formed correctly.
This version doesn't work for me, for some reason. Version 1 works, and version 7 works. But version 8 doesn't let me view the graphs of data being collected. No visual feedback of them even being created when I drag across the screen. But it does allow me to adjust the settings for the graph I can't see lol!
This looks fantastic! I've downloaded the jar and when launching on my Mac it hangs indefinitely after displaying a single HINT line in the console. Any suggestions? I'm running Catalina with java 13.0.1. Thanks!
Hi. Unfortunately I don't have access to a Mac for testing. I know people have used older versions of TelemetryViewer with macOS, but I don't know the details. If you know anyone with a different version of macOS, maybe try to see if this problem only happens under Catalina. You could also try with other versions of Java, such as Java 8 or 11.
I just tried this too on my Mac with no luck. Downloaded your latest version, and downloaded Java 11 based on your feedback in this post. It just hangs and doesn't start. Running Monterey iOS. Bummer!

@@upgrdman I let it update, so hopefully the newest one! haha. The OS is Windows 7. I'll go see what version of Java I updated to.
@@upgrdman Verion 8 Update 11 ((build 1.8.0_311-b11), is what it says when I click "about Java".
The newest version of Telemetry Viewer requires Java 9 or newer. That should fix the problem.
@@upgrdman okay thanks. I was hoping that letting it auto update that it would be the latest version. Guess not! I will try to find that version.
This looks fantastic! I've downloaded the jar and when launching on my Mac it hangs indefinitely after displaying a single HINT line in the console. Any suggestions? I'm running Catalina with java 13.0.1. Thanks!
Hi. Unfortunately I don't have access to a Mac for testing. I know people have used older versions of TelemetryViewer with macOS, but I don't know the details. If you know anyone with a different version of macOS, maybe try to see if this problem only happens under Catalina. You could also try with other versions of Java, such as Java 8 or 11.
I just tried this too on my Mac with no luck. Downloaded your latest version, and downloaded Java 11 based on your feedback in this post. It just hangs and doesn't start. Running Monterey iOS. Bummer!
Cool software but what version of Java should I be using for year 2023?
It should run fine with the latest version of Java, but there are some command line flags that need to be added. Details are on my web site:

@@upgrdman Hi, thank you for this magnificent software! I'm running the latest java jre, v0.7 runs fine but i'd really like to use the v0.8 for the multiple connection to improve my project. The problem si that I'm not able to make it run... tried to copy the command line flags and it always gives me "Error: Unable to access jarfile TelemetryViewer_v0.8.jar" what am I doing wrong? Thank you again
Thankyou. But how to save the collected data ?
Click the "Export" button to save the data to a CSV file.
Hi, I notice that dataset is 27 maximum, can we increase it to 30 in the source code?
It's almost limitless. What gives you the impression that 27 is the max?
I put in data set 27, and I got error, "corrupted telemetry data", I am studying the source code now, nothing to say its limited, need to check what is wrong, can we start dataset to "1" instead of "0", how to do this?
This is an Awesome program..! let me ask you, is there a way to run this online on a browser?
No, it's not a browser-based app. I've thought about doing something like that, but don't have time to figure out all of the issues with porting it to HTML/CSS/JS.
@@upgrdman this would be a great online utility.. very helpful.. thank you for replying
