Hi, I've been developing a simple water level sensor with the VL53L0X and i'm having trouble putting it into the enclosure that is protected from the moisture. I've been mainly experimenting now, but one of my problems is mounting the sensor behind glass or something like that. I'm happy to glue that on over a hole or something, but wanted to figure out what works.I've followed some of the video's around crosstalk and have made a 3d print that should help (please see photos).The sensor works as expected in the 3d printed element, but doesn't work properly when i add the glass lens filter. I took the lens filter after trying a few other things, but not being great at materials, i wanted to be sure, so i tested with this filter from one of my camera lenses.I think i'm doing everything correctly, albeit not professionally, but can't get it to work.I would be greatful if somebody could point out some issues that i might have made.  

I hit Debug, the console says, "Waiting for debugger connection", after a few seconds the debugger stops in some low level place like Reset_Handler in startup_stm32f411ceux.s, then it resumes, flashes the code, and runs the program. Is that normal?I dislike this behavior because it opens some source file which I then need to close to get back to my code.Please note I'm not talking about "break in main", which is unchecked. This break is before the code is even flashed, and it resumes automatically. I don't have any breakpoints set.I'm using STLINK-V3SET.

If anyone Work on project that interfacing Can transceiver TJA1050 with STM32F412RET6 , if yes i hope  anyone send Example code that work and clock configurations ,, the loopback mode work correctly .. but in normal mode problems start ... and operating voltages of TJA  

I am trying to put nfc02a1 with wl55jc1I have set the settings as required in Dynamic NFC tag IC expansion board based on M24LR04E for STM32 NucleoBut some of the pins required to be set have other functions in wl55jc1I have reset them to match nfc02a1But only led2 worksWhat is the suggested solutionThanks in advance

Hi  I am trying to send some CAN-bus messages from a STM32H723VGT6 mounted on a BIGTREETECH SKR 3 EZ V1.0 I am following this video to send standard CAN messages in external loopback mode (https://www.youtube.com/watch?v=kXyzaaSk6Qs&t=568s&ab_channel=ControllersTech). But whenever I reach the point where I add a message to the TxFifo I get the error 0x20 -> "Parameters error" but I am not sure what could be causing this Here are the parameters I set for FDCAN1 To avoid additional variables we used the internal clock of the microprocessor, here is the final frequency of the FDcan peripheral And the transreceiver mounted on the board is the mcp2542fd-e/sn  

Dear all,Background: I am in a student project trying to build a robot for RoboCUP - SSL. We have elected to go with DF45L035048-A from Nanotec. I have not received the motors but I saw that it is possible to import a new motor with a .json file. I know the specifics of the motor (from the datasheet) but I do not know the format of the file.Question: Is there a template for the .json file that I can use which MC Workbench6 will accept so that I can started even though I do not have the motor?Kind regards

Hello,currently I'm using stm32l496 in that i want to wake up the controller from the standby mode on an external interrupt.i configured pin PC13 (supports wake up functionality) as an external interrupt with rising edge , now when the MCU enters into the standby mode, upon receiving external interrupt will the device wakeup?

Hello, I am doing a project with STM32F411RE NUCLEO board. I have downloaded the zip file from the web builder GRBLHAL. i have attached the file here. And I have successfully imported the zip folder onto the stm32cubeide. So for that project I want to add communication through SPI. and there is a SPI communication can be used for that project.as in my previous query, i came to know that with UART communication, USB connector which is connected to cn1 of the board and raspberry pi USB connection - i am able to communicate. as i understood that, to communicate between raspberry pi  and stm32, i don't need to connect tx of pi -> rx of board, rx of pi -> tx of board, gnd to gnd. but can able to communicate through a connector. will that be possible with spi communication also. if no, then how can be the easy way to communicate between raspberry pi 4b and stm32f411re. and i forgot to mention that, in that file i am not able to find uart communication, i can only see the header fi

The datasheet is a bit light on details about what to do with these pins if you are not using USB at all. Can I ground both of them, or does there need to be a supply voltage on VDD33USB?One of the notes on the Absolute Maximum Ratings section in the datasheet says "All main power (VDD, VDDA, VDD33USB, VDDSMPS, VBAT) and ground (VSS, VSSA) pins must always beconnected to the external power supply, in the permitted range," but I don't know if this means that ground is a valid "external power supply."For example, in other parts of the datasheet it says that VBAT must be connected to VDD even if a battery is unused. However, it also says VDDSMPS should be connected to GND if unused. So I am unsure about the meaning.

I’ve created a SPI peripheral as a slave in transmit-only mode. It operates in circular mode DMA and generates a complete callback every 20 milliseconds. Upon receiving the complete callback, I want to modify the source address of the DMA request.Currently, I achieve this by aborting the SPI and then initiating a new DMA transfer with the updated address configuration. Why do I need to change the DMA Source Address?I’m implementing a ring buffer pointer.  Note: I’ve utilized the HAL framework for this implementation.     

Hi there Touchgfx team!I've this screen requirement, a list of settings. I'm doing it with a custom container that I already created. My custom container has a flex button with text(on the left) + the text on the right. What I need is that once the user presses the button, the text color changes to white. Once its released, changes back to black. The flex button works perfect, but I'm having trouble setting it up for the right text. I could add the white and black images, or creating a function to check if the button is pressed every n ticks, but that seems cumbersome. Is there any other way?  Thanks a lot in advance

Hi there Touchgfx team! I have a view with a custom container list as in the ListLayout example.  class test_selectionView : public test_selectionViewBase { public: test_selectionView(); virtual ~test_selectionView() {} virtual void setupScreen(); virtual void tearDownScreen(); /** * Handler of list element clicks. */ void listElementClicked(CustomListElement &element); protected: static const int number_of_select_test_kit_list_elements = 30; CustomListElement select_test_kit_list_elements[number_of_select_test_kit_list_elements]; // Callback that is assigned to each list element Callback<test_selectionView, CustomListElement &> listElementClickedCallback; }; I would like to have the number of elements in the model, and access it with a get method. Right now, you can see I'm harcoding the "30" value in the view. I already created number_of_select_test_kit_list_elements in the model and created the get method, because that numb

Hi community members,I’m currently working on a project where I want to deploy a Convolutional Recurrent Neural Network (CRNN) on an STM32 MCU using X-Cube-AI. The network structure includes convolutional layers followed by GRU layers, with a reshape and permute in between to convert the 4D tensor output to a 3D input tensor for the recurrent layer. Initially, I implemented this in PyTorch (exported to ONNX), and then tried TensorFlow Keras (exported to TFLite). Unfortunately, I’ve run into errors with both approaches during the import process in X-Cube-AI.Error MessagesWhen importing the ONNX model from PyTorch, I received the following error message:TOOL ERROR: Shape and shape map lengths must be the same: [192] vs. (CH_IN, CH)I built the same architecture using TensorFlow Keras to see if this would work, then exported it as a TFLite model. However, importing this TFLite model into X-Cube-AI produced the following error:INTERNAL ERROR: Inconsistent in/out tensor shapes in transpose_6

I am trying to program a STM32F411E-DISCO with a new MacBook Pro. I installed STLink and then I installed the IDE. When I try to debug, the IDE says no STLink is detected. Here is a screenshot of my debug config. Here is a screenshot of the STLink Upgrade windowAll the jumpers are on the board. Thanks for your help!

I m working with STM32 MCU from last 3 years  i made many boards for STM MCU but i never face the problem which I'm facing now. In past i made boards for lower pin packages ( up to LQFP 64 ) mostly they have single power input pins this time i made a board for STM32G474 ( LQFP 128 )  it have several power input pins and i connected all them in design,Now what issue I'm facing is that when i started firmware development i noticed that CPU do not run code automatically i need to disconnect it several time from power and then its run code and start consume power, in working condition circuit draw 0.09mA  from 12V rail and when its not start code its consume 0.03mA.where is problem what I'm doing wrong here?Is that something with reset pin? Because i did not pull it up externally. 

Hello,I'm using STM32H743 to send and receive REST API. I'm using FreeRTOS, LWIP and mbedTLS to communicate with server. I have the same application working WELL using STM32F765 with MCAL layer of course modified to STM32F7 but using H7 I can see this error "Unknown Record Type" when fetching input and reading input record. I tried solutions like optimizing cipherSuite but was not useful.

Dear,We using an ADC in our application at 1MspsThe ADC is always running in a circular DMA mode.To start the buffering of the samples we use the Analog watchdog 1. So when the input signal goes outside the analog watchdog thresholds the function "HAL_ADC_LevelOutOfWindowCallback()" is called.This works fine, but now in this callback we give a signal to other code that the buffering of the samples starts and we would disable the analog watchdog 1.Stopping the analog watchdog 1 interrupts does not work for us and he keeps going into callback "HAL_ADC_LevelOutOfWindowCallback".What are we doing wrong to stop the analog watchdog interrupt?btw the ADC and DMA should never stop while disabling the analog watchdogFirst method: (preferred for us, must be very fast)   ADC_HandleTypeDef *pAdc = pHdlr->pHdlr_adc; LL_ADC_DisableIT_AWD1(pAdc->Instance); CLEAR_BIT(pAdc->State, HAL_ADC_STATE_AWD1); LL_ADC_ClearFlag_AWD1(pAdc->Instance); LL_ADC_DisableIT_AWD &nbsp

Hi there Touchgfx team! I have a textarea and 2 images inside a custom container. From my view, I create the custom container and then call a custom container method to update the x,y of these widgets like this:  storage_full_image.setXY(battery_x, battery_y); battery_image.setXY(battery_x - 25, battery_y); header_date_text.setXY(header_date_x, header_date_y);The 2 images move without problem, but the textarea remains fixed. I'm invalidating all 3 widgets after updating the XY. Is there a different way to update the XY of a textarea?Thanks a lot in advance

I want to implement a firmware upgrade feature. Currently, I am doing it as follows: on the M4 core, I have a bootloader and an application; on the M7 core, there is also a bootloader and an application. The M4 application is located at address 0x08120000, and the M7 application is located at address 0x08020000. I’m not sure if this approach is feasible or if there is a recommended upgrade method. Currently, the jump between the cores does not succeed, and I don’t know why. Are there any specific considerations when performing a jump between dual-core firmwares?
