Touchgfx integration with Simulink in matlab

Im using stm32h735g-dk and i was thinking to start model based development using simulink in matlab.
I already done a cluster prototype using touchgfx and stm32cube ide
now i need to shift from cube ide to simulink using same gui is it possible??
If its posssible how will i integrate with simulink
i have already licenced version and stm embedded packages on simulink and embedded coder
can anyone help me with a guidance how to integrate without using cube ide

Neural Network in Simulink and Matlab training.

Hello to all!
I would like to share with the Matlab and Simulink community this video about Neural Networks in Simulink.
This is a series of videos that use a multilayer perceptron implemented in Simulink as a case study. Why Simulink? Because it's a visual and intuitive modeling tool, you can see the forward propagation of this network and better understand the flow. The objective of this series is to show the implementation using Simulink for both simulation and Arduino, as well as its training using Matlab and Matlab with Deep Learning Toolbox, and a video of training with Python.
The video is in Spanish, but the Simulink model is available in English for the entire community; subtitles are also available.
The files are located in the first comment of each video. We hope you find it interesting and enjoyable. Best regards!
Here I share the link to the first video.

Hello,
I've successfully tested the Processor-in-the-Loop (PIL) workflow in Simulink using a TI F28069M LaunchPad, following the standard examples provided by MathWorks. The PIL block, code generation, and communication all worked without issues.
Now, I’d like to run a similar PIL setup using the Infineon TLE9879 EVALKIT (based on an ARM Cortex-M0), which is not officially supported by Simulink as a target.
I’m wondering if it’s possible to configure PIL manually or via custom workflows. For example:
  • Can I create a custom PIL target using Embedded Coder?
  • Would I need to port rtiostream manually for communication over UART?
  • Could I somehow integrate with Keil µVision (which I use for TLE9879) to build and run the generated code?
  • Is there a workaround to simulate PIL behavior using a non-supported board?
My setup:
  • Simulink R2024b
  • Infineon TLE9879 EVALKIT
  • Keil µVision 5 + Infineon Config Wizard
  • UART and JTAG interfaces available
The main purpose is to validate control algorithms and measure execution time, not to implement a full HIL system.
Has anyone attempted PIL with a custom or unsupported microcontroller before? Any tips or resources would be greatly appreciated. Thanks in advance!
Hello Everyone,
I'm running an IoT project at my university using a free . Basically, my system uploads the sensor data to 4 different fields of a ThingSpeak channel and I'm reading from or writing to the channel through Simulink. I have a few questions regarding this topic:
  1. I'm trying to upload to the server every 3 seconds (which seemed to be providing the best results so far). Since the channel only accepts data transmit every 15 seconds, what is the optimized upload interval rate to match the interval rate of the channel? Because otherwise I have realized that my interval rate can go up to 1min sometimes for some reason.
  2. Is reading from/writing to the channel through simulink while the system is uploading data to the channel slow down th whole process? What is your overall suggestion in this case?
I'm excited to hear your suggestions and experiences!
Regards,
Ege
Hi Everyone. I am facing a problem while connecting the FMU to the buses. I have one FMU which expects 9 inputs and I did clarify the same while using bus creator. But in the end i am getting this error which i am trying to solve for couple of hours but didn't get any solution. So if any knows about the same please help me. I would give details as well if you need any other information.

I am using simulink to generate a simple ADC sampling code. I configured ADC module in software mode, which updates the sampled value according to the sample time configured in the module. I set the sample time to 1e-4, 1e-5, 1e-6 respectively. But it seems that the sampling speed did not reach the value I set. I suspect it has something to do with the read and write operations, but I am not sure if that's the reason.
I also tried to do it using PWM event to trigger the start of conversion of ADC. Same problem happened. Because I connect a potentiometer and turn its knob slowly, the Graph on CCS is correct while when I turn it very quickly, the graph is not able to keep up with my movements. So the sampling rate is surely not enough. I wonder what I should do to successfully configure this model, thanks in advance!
I am facing an issue in data store memory block using store memory Read and write Block in matlab simulink. I have attached the screen short in which the posed error has been depicted.
Hi, I want to collect the simulation data by using NASA HL-20 model, then the data will transmit to ThingSpeak. However, I don't have the block for ThingSpeak Channel at the Simulink Library Browser. Is it because the block has its own version of simulink (meaning I have to update my version) or is there any else that I don't know? Besides, can you suggest which methods are suitable for me to successfully transfer the simulation data to ThingSpeak?
Simple app created using Simulink support package for Android device. App created but data is not getting logged on thingspeak channel the error msg on app log is as attached.
I am trying to simulate a 3 phase induction motor on Simulink by using its dynamic model. This is the information in its datasheet:
It also has 4 poles and J = 0.0117 kgm², star connection. After calculate parameters, I get these values:
Lm = 0.176 H; Rr=Rs = 0.613Ω; Llr=Lls = 0.00669 H.
Also in the datasheet, they said that the output torque = 705 Nm at speed 35 rpm, but the model cannot reach that value. The simulation motor run backward if applied torque greater than 70 Nm ( at about 1200 rpm). But in reality, this motor can withstand 705 Nm, I have seen it run.
Can someone help me with this problem? Thank you

I have a datasheet of an induction motor (as figure below). I want to simulate it on matlab/simulink, but I don't know it's parameters (Lls, Llr, Lm, Rr, Rs).

I tried to search about open circuit test and blocked rotor test to determine these parameters, but some of information doesn't appear on datasheet and I don't have the real motor to test on it (datasheet is only think I have).

Could someone help me with this?

Are you looking for ways to keep your students engaged in a virtual setting? Would you like to spice up your courses with hands-on projects? Using Arduino Engineering Kit, you can achieve these. Due to COVID-19, many instructors started to look for creative ways of giving students a lab experience. Some of them chose to create virtual labs, some of them designed hardware projects with low-cost hardware or integrated hardware projects kits to their curriculum. If you are interested in how Dr. Azadi from San Francisco State University used Arduino Engineering Kit during the pandemic to teach his Mechatronics course, check out these articles:

Hi, I'm trying to send with a serial connection a signal. The signal is just a byte (uint8) that I want to send to my evaluation board every 1 millisecond using Simulink. How can I do that? I tried using the Serial Send block, but the result is different from what I expected to see. Then I tried to use the To instrument block, but I don't know why there isn't the port COM 5 so I couldn't use it.

One of the objectives of lab-based instruction can be to develop students’ familiarity with hardware equipment. When students could no longer come to their lab in person, educators at HTW Dresden developed a MATLAB app using App Designer to replicate the controls on lab equipment such as a signal generator and oscilloscope. Read this article to learn more about how Dr. Henker and Dr. Kelber virtualized their electrical engineering labs.

If you use Simulink or Simscape models for your virtual labs, you can create an interactive display of controls and displays within your model diagram using blocks from the Dashboard library. To do so, connect block parameters to control blocks (knobs, buttons, and switches) and signals to displays blocks (scopes and gauges).

New customizable Knob, Vertical Slider, and Horizontal Slider blocks introduced in R2021a let you choose your own background image, foreground image, handle or slider image, and scale appearance. By combining these with custom gauge blocks, you can create intuitive and photo-realistic dashboards for interacting with your models, such as in the image below.

PMSM phase loss simulation

I am trying to simulate the PMSM in fault mode with phase loss at 0.25 sec, but the simulation results are incorrect. For example, the rotor speed changes too much when a phase is missing. I tried to assemble the model in dq coordinates and abc coordinates on my own, but the results are the same. Who can tell you how to modify the engine model so that the simulation shows the correct results?
