Good afternoon everyone,I am currently working on a predictive maintenance projet using vibration classification with the MLC of a LSM6DSOX.I would like to try using several decision tree at the same time (with a maximum of 8 according to the datasheet), 3 for example.I have some trouble to build my .ucf file.I tried to do exactly the same than with a single decision tree, but it does not work.Actually I can build it the .ucf file, but I am getting "0x00" (default value) output in every channels of my MLC, whereas it should not be possible with the configuration I made.So I think I made a mistake during the configuration step on Unico, but I cannot see it.Maybe there are requirements I did not follow, or I may have to change my MLC configuration ...Is there any tutorial that explain how to configure the MLC with several decision tree ? Or can anyone explain me my possible mistake

I have a simple binary classification ANN model built with Tensorflow Keras and converted as Tensorflowlite model. This model gets imported and analyzed on the cubeMX tool without any errors. There is no IO input required for this trial model, so allowing random numbers for input features. Without any modifications to the code imported to STM32CubeIDE and build succeeds. While debugging, i can see that inside MX_X_CUBE_AI_Process() --> aiRun() method is returning error code 23 and error Type as 18. Since the analyze function succeeded during code generation process, i expected that this code runs without any modification. Any suggestions please?

It is now available a section of the Community page dedicated to New Ideas (LINK). This new "zone" is intended for ST products' users to give the Community technical feedback on available product areas.MEMS&Sensors community group has especially a couple of pages dedicated to the MEMS Machine Learning & AI ("X-factor products") and SensorTile.box reference tool:

I am new to STM32 and wants to implement a neural network application on  STM32H743ZI. Please provide me some guide lines

Hi,STM32L5 has Cortex-M33 processor. In the official documentation it says that Cube.AI supports Cortex-M CPUs (including M33). Why is it still not possible to choose AI library for Cortex-M33 on STMCubeMX IDE? Is there anything fundamentally different that there is no support? Regards,SK

I am using the STM32H745ZI-Q Dual Core MCU. My workflow is to generate the AI library using a Single Core processor and then copy the project into my Dual Core. Now I am trying to use External Ram Configuration (STMCube) to map the activations NOT into a external RAM but into another Bank (AXI SRAM for example. Address: 0x30000000) but without any luck. Is there any way I can allocate the Activation buffer on another RAM Bank?

Hi, everyone have someone know where can find the voice recognition of STM32L1 application?I just need few Japanese vocabulary to identify command, but I didn't find it. AWS didn't match my request. Could you please help me?

How do I run larger ML models (greater than 10MB)? Is interfacing external ROM with QSPI and memory mapping it alone sufficient?Can I use an SD card instead? Can the memory card be memory mapped to internal flash? Can I paste the weights on the memory card using my PC and have the ML model request the SDMMC everytime it needs to access some data?

Hello,I am undergraduated student in South Korea. Right now, I've ran into a little problem during my research. So I'm uploading this message becasue I believe that you guys can help sloving this probelm. I wanted my model to work in right way while using sensor tile but even though I've tried a lot of time, it didn't work properly. Simply speaking, I quantized my model with npz file, which needed verification. I converted quantized mdeol file through code generator (STM32 AI5.0) and changed the converted result (C,H file) with function pack file (fp-ai-sensing1). At last, code about part which needed softmax didn't work due to absense of output meta info. So like a blue part in attached photo, I arbitrarily did 'hard coding.'I tired asc on 2 model (1.model provided by function pack 2. model I've exercised) and it showed conflicting results. In case of model provided, it worked properly when went through same progress. However, in case of my model, e

When using the CubeMX code generator, I am not able to include the Cube AI library when selecting STM32H745ZI-Q. Is there a way to use one of the H7 Family Dual Core MCU's with the CubeAI library? Or is it possible to generate the necessary library using a single M7 or M4 cortex MCU and then copying the generated files into the Dual Core project?

Hello all,I have bought a SensorTile.box which has LSM6DSOX, an IMU with Machine Learning Core. I am seeing some decision tree-based examples/implementation of LSM6DSOX.If I train a new model for my application, My query is how to load that model into LSM6DSOX of SensorTile.box. General examples of LSM6DSOX says I need to insert the LSM6DSOX (DIL 24 socket) in an ST MEMS adapters (STEVAL-MKI109V3) and use Unico tool. How to do that for SensorTile.box?Another query is whether any other low-cost option available to load a new decision tree model into the LSM6DSOX chip without buying that STEVAL-MKI109V3.Thanks in advance.

Hello, I am under graduate student in Korea and I have a question to solve a little of problem.I tried so many time to classify at sensor tile.In my case, I quantized my model with validation npz and converted to C code by codegenerator which is as known as STM32_AI 5.0.0. After converting, I changed asc.c asc_data.c and .h file too at fp-ai-sensing1 source. Finally I added the softmax code because code doesn't exist output meta data in this function pack.​I tried asc(acoustic sound classification) about two models(provided model by function pack and made new model by me) and I get the results. First result is perfect. It works very correctly. Second result displays

ing the sensor box. But as soon as the intensity value changes the graph and data collection freeze. In fact, I noticed before I finished the example and was just plotting the three accel values that the graph would freeze occasionally, but never reproducibly. Is this a bad USB cable, MCU crashing, LSM6DSO)X crashing? Any idea why I can;t get the simple webinar example to work robustly?

Hello!My problem is that I don't see the components in the Additional Software menu.I did everything strictly according to the instructions specified in the official video "Getting Started with STM32Cube.AI". Components installed as shown.CubeMX reinstalled, the computer rebooted, but it did not help. Touching Refresh button also has no any effect. What could be the problem?
