Dear Forum,
I tryed to use my STM32F767zi nucleo with simulink.
I followed the steps from the training material.
In the end I ended up with only 2 libraries rather than 5 as in the training video !!
Where are the missing 3 libraries?
I use Matlab 2020a
Thank you

Hello,
it's been a couple weeks that the webrowser client seems to have issues for me.
I can't move the chart with my mouse anymore. And the Average option doesn't do anything, it is always displaying all the datapoints.
Same with the type of points, it is stuck on line type whatever I ask.
Also it will not update the page automatically when new points are uploaded, I have to hit F5 to refresh myself.
I can still control the number of days displayed though.
I tried on brave, firefox and edge and it all behaves the same.
Edit : I see that there are already multiple threads referencing some of those issues already. So the moderator can delete the thread if he feels like it is unecessary.
I get the following error message when using a DELETE command.
I am using the correct api_key and channel ID Error Response: { "status": "401", "error": { "error_code": "error_auth_required", "message": "Authorization Required", "details": "Please provide proper authentication details." } }
I just cannot find out what I'm doing wrong. I've used Postman and Curl apps.
Can anyone help?
how can I do to get those informations?
Ich erinnere mich, dass die Visualisierungsfenster verschoben werden konnten. Das geht nicht mehr? Wer kennt den Trick?
I can't or it's not working anymore to change the position of the widgets on the channel panel.
I tested on Chrome and Firefox.

I noticed a couple new replies show up on the recent poll a day or so ago, but since then, the page can't be loaded anymore in any browser I've tried.
Is MathWorks going to spend 5 years starting in 2024 making Python the #1 supported language?
I'm not sure it's authentic information, and am looking forward to a high level of integration with python.

I wanted to say that I am thoroughly enjoying my ThingSpeak channels and I often discuss with friends and associates the technical and documentative aspects of the MathWorks/MatLab/ThingSpeak platform and all the possible benefits for engineers, researchers, scientists and students across the globe.
My pubic channel demonstrates to them how useful it is to see simple data in a visually intereresting way. I hope my efforts will bring ThingSpeak more subscribers in the new year.
If there are any questions, let me know. (I owe Christopher a story here about my Alaska system. Soon......)

edited update, only one channel used publically now in 2025. I still owe CS a story...
Hello Everyone,
I want to model an electric vehicle in simscape electrical, I have few quiries regarding it.
- I have modelled an 3-Phase inverter, and used ee_getPowerLossSumary to get switching losses, and the results are okay as i was expecting, but now is there any other function to calculate conduction losses?
- I want to connect a BLDC motor, I have few parameters from manufacturers datasheet, but not all the parameters, so what would the best way according to your understanding, to model motor losses (Copper + Core).
I'm trying to calculate major fundamental losses of an EV. Looking for your inputs on this.
Thank you!
I am sending data to Thingspeak chanels from an ESP8266. I am saving data on the ESP memory which is collected at 5 minute intervals . I have created a trigger function which sends the data on demand in batches from the memory, which means there could be varying number of Data points from say 10 to 50.However I have notice recently whilst my code tells me the data points have been transmitted not all get recorded in thingspeak, are there restrictions which cause this problem and if so what is the solution please?
i am trying to build a pulse radar using barker codes. i modulate the barker code and sine wave and added some noise as well. then i attached a matched filter whose parameters are shown in the image. and then made an attempt to demodulate, which i don't think is right. can someone please help me with the matched filter- like are the coefficients right? and also what else can i add remove and demodulate/detect.
PLEASE HELP ME OUT HERE I HAVE BEEN STUCK FOR QUITE A WHILE AND UNABLE TO FIGURE OUT HOW TO GO FURTHER
I need your help.
I am working on a simulink model and I want whenever run it, I give it some inputs. e.g. I can give it different heights when I want it to work.
I defined a file.m in the same directory and same name. but whenever I run it I face this error:
What should I do?
Has anyone ever been in this situation. When I use the ODE toolbox to find some complex system of equations with coefficients that vary greatly in order of magnitude, the results are completely incorrect. If you are in the same situation or know a solution, welcome to discuss with me, thank you!
Hi Any one knows how to interface delta VFD MS300 with matlab to control motor speed and
Hi, while I can download data from the thingspeak page as csv older than 5 months, I can't read history data older than one month.
The data exists on the database.
This are my requests:
https://api.thingspeak.com/channels/667773/fields/1.json?start=2023-11-23T01:01:10.000Z
The same results. Every day the older value date is higher by one day.
Today the older value day is: 2023-11-25T02:13:46Z
Why? Is there a limit to history data loading?

Both a FIK & license.dat are accessible during the install. There is 80GB of free disk space as well. No one is logged in to Windows when the install is performed. What does status -2 mean?
Thnaks!
I have encountered a problem. I want to study the direction of PHEVP2 configuration energy control strategy, but the whole vehicle model has stumped me. I don't know how to proceed, and every time I run, an error message will be reported. I don't understand where the problem lies?
