Hi,I configured the STM32U5G9VJT6Q to use QSPI to interface to a NOR FLASH ( MT25QL128ABA1EW9-0SIT ).Because of other connectivity, the only option for the data lines (Data [3..0] as highlighted in yellow in the attached screenshot) is "Port 2 IO [7..4]". All other options in the drop-down menu next to "Data [3..0]" are either red or disabled.I need to be absolutely sure of the connectivity and that it will work (preferably using the HAL drivers).Does that configuration work?With reference to the pins table in the attached screenshot, do I need to connect the data lines as follows: - PH9 (P2_IO4) connected to QSPI flash memory Data 0- PH10 (P2_IO5) connected to QSPI flash memory Data 1- PH11 (P2_IO6) connected to QSPI flash memory Data 2- PH12 (P2_IO7) connected to QSPI flash memory Data 3 or in some other ways?Thank you  

Hi,on the STM32U5G9VJT6Q, according to the documentation and also to the Pin export from CubeMX including the Alt-Functions, PH15 should be able to be set to TIM8_CH3N.But in CubeMX (see screenshot below) when I select Channel 3 PWM output it sets it to PB1 (instead of PH15).How do I set TIM8_CH3N onto PH15 (i.e. pin 62 in part number STM32U5G9VJT6Q)?Especially using the pane on the left (instead of trying to select the pin int he micro's IC view).Thank you   

Hi,on the STM32U5G9VJT6Q, when I click on many pins such as PD5 (screenshot below) it shows GPIO_Analog but there does not seem to be any ADC channels (or other analog functionalities) connected to it.What does setting it to GPIO_Analog do?Can I still assign somehow a ADC to PD5? If so, how?Thank you :)   

Hi guys,This has likely been covered before so please feel free to point me to it.I'm trying to set up the LSM6DSOX Pedometer to store count to FIFO, but having no luck.I am not using the Library, as it is not easily ported to my uC.Would anyone be able to highlight for me the registers I need to set up for basic operation, so that I can tinker from there?I have been able to set up the pedometer to interrupt, but not write to FIFO.I'd also be interested in the steps to read from the FIFO, but imagine that this will be easier once I'm writing correctly..Thanks,Ben

Hi all, I'm playing around with STM32H747I-DISCO eval board and the stm32ai-modelzoo demo. I've managed to train and evaluate a model with my custom dataset using the script in "image_classification\src\stm32ai_main.py" Now I'm struggling with the deployment of the model. I tried using the deploy script in "image_classification\deployment\deploy.py" but I get the following error: ModuleNotFoundError: No module named 'models_utils'   Any ideas what's going wrong here? The error isn't very descriptive (to me at least) so I'm a bit stuck. Sorry if this is a simple question, coming from a Hardware and FPGA design background using VHDL where everything is very explicit and strongly typed, I really struggle with the layers of abstraction that Python libraries bring.

I'm using SPI on STM32H563 with DMA to interface to a ST7789 LCD controller.  During the LCD initialization I'm using a loop to send a series of command/data bytes using the HAL_SPI_Transmit_DMA() HAL function but the DMA status never goes back to READY (see my function below). void LCD_IO_WriteMultipleData(uint8_t *pData, uint32_t Size){  /* Swap endianes */  ConvHL(pData, (int32_t)Size*2);  DC_H();  if (HAL_SPI_Transmit_DMA(&hspi3, pData, Size*2 ) != HAL_OK) {    Error_Handler();  }  while (hspi3.hdmatx->State != HAL_DMA_STATE_READY);}Function hangs on the while loop at the end waiting on DMA to complete.Please see attached images of .ioc SPI and DMA configuration. 

May I ask how to convert the IR channel ADC value of VD6283TX45 to IR optical power, only the RGB channel is converted to Lux in Driver, and there is no description about this IR optical power in Datasheet. 

Hello everyone,i am trying to read the device unique id of my stm32h7b3 mcu, but get a bus fault on line 2:   uint8_t* uid_base = (uint8_t*) 0x08FFF800; uint8_t i = uid_base[0];  Do you know what could be the problem ?

Good morning to all,I am wanting to make a simple numeric keypad where I only press numbers and they are seen in a text area and then when I press a button it compares it with a char and if it is the same it does one thing or another.My problem is that I can't see anything in the text area and if I send in the sprintf directly the variable contrasena_ing (which is of type char contrasena_ing[11]; ) it prints and the delete button erases but in fact it prints anything (from touch gfx the range of ascii characters is ok).what am I doing wrong?  Info_5View::Info_5View() { } void Info_5View::setupScreen() { Info_5ViewBase::setupScreen(); contrasena_ing[0] = '\0'; pos = 0; } void Info_5View::tearDownScreen() { Info_5ViewBase::tearDownScreen(); } void Info_5View::service_unlock() { // Override and implement this function in Info_5 //Unicode::snprintf(unlock_textBuffer, UNLOCK_TEXT_SIZE, "%s",contrasena_ing); //unlock_text.invalidate(); //char contrasena_ing[11]; } vo

Hi, I'm pretty new to STM developement. I tried use "SubGhz Ping Pong" example in the cubeWL package, successfully. Now I search to establish a real com' between two STM32WL55JC1, where they can exchange data, etc... The different driver, API, layer make a real fog when you're a beginner. In differents manual theres no details on what do this function or this, and search in "radio_driver.c" is not very helpfull. Someone here can help me to understand how inplement and use those function ? Thank you very much.

To secure my bootloader against erroneous writes from the application I want to enable write protection on it. But since for some things the bootloader needs to modify data inside its partition (security counter update and key invalidation), I can not just enable write protection and be done with it. I would need to disable it at some point and reenable it again. Best case without rebooting in between.Now what I am trying to understand ist when the WRP setting actually takes effect, so how dynamic I can use it. The reference manual says:"To validate the WRP options, the option bytes must be reloaded through the OBL_LAUNCHbit in Flash memory control register"But validation is not enabling. So when can the register be written and when does the change take effect?I think my question is quite similar to the following, but that was never solvedhttps://community.st.com/t5/stm32-mcus-security/about-read-out-protection-write-protection/m-p/162290

Dear,I'm starting with OP-TEE on STM32MP15x line. I bring-up the board as described here and built the optee_example_hello_world as described here. However, I got the error code below:TEEC_Opensession failed with code 0xffff0008 origin 0x3Checking the boot messages, I realized that the profile system_services is used. This way, it is not possible to run any TA. So, is there any already compiled image for STM32MP157C-DK2 board that allows running a TA or do I have to modify the image to enable it? Thanks! 

Hello,What does the red “S” in the CubeIDE outline window mean? Is there a description of the respective markers in CubeIDE somewhere? 

Hello, I would like to know if it possible to use a 48MHz TCXO instead of the 48Mhz crystal specified in the datasheet of the STM32WL33 ?Standard crystal are at minimum +/- 10ppm at tolerance and this may not be sufficient for our application. If yes, do I left the OSC_OUTPUT in floating ? Best regards, Schaeffer G.  

I noticed that the FreeRTOS task function template generated by CubeMX lacks a defensive programming practice recommended in FreeRTOS examples and documentation. Current Generated Code:   void TaskFunction(void const * argument) { for(;;) { // Task code } }   Recommended Pattern (from FreeRTOS examples):   void TaskFunction(void const * argument) { for(;;) { // Task code } osThreadTerminate(taskTaskHandle); // Safety guard if loop is ever broken }   Rationale:1. While the infinite loop means the code after it should never be reached, having osThreadTerminate(threadID) (vTaskDelete()) acts as a safety guard2. If the loop is unexpectedly broken (due to a bug or other condition), the current implementation could lead to undefined behavior3. This pattern is shown and recommended in official FreeRTOS examples and documentation4. Adding this guard aligns with defensive programming practices Impact:- Low: This is not a functional bug as the code works correct

Hi all,I have an STM32F746G-DISCO board bought some years ago and I am trying to use it with a Pololu Dual VNH5019 Motor Driver Shield for Arduino (https://www.pololu.com/product/2507) to drive a DC motor.I successfully created a TouchGFX application with a couple of buttons and a slider with which I can control the START/STOP status of the motor and the duty cycle of a PWM signal which controls its speed.The shield uses Arduino signals D2, D4 as Motor 1 Direction inputs A and B respectively, D6 as Motor 1 enable signal and D9 as PWM signal.All signals work correctly except D4 ( = M1INB) which from the schematic diagram of the discovery board should correspond to signal PG7. Unfortunately PG7 seems to be not available at all in the GPIO configuration panel of the board in STM32CubeMX.I don't not if this could be a problem with the particular revision of the discovery board I have.Unfortunately I am unable to find its revision (I bought it some years ago), but I attach a couple of

Hi!We are developing a product that should provide a KINEIS satelite protocol support.As claimed on their website, thay have a partnership with ST. According to this ST supports it.Could you please provide more info according to this? Any code examples or hardware Reference Design?

Hello Everyone,I'm seeking guidance on how to connect an external Ethernet module using the RMII interface to an STM32 microcontroller. The challenge I’m facing is that CubeIDE does not allow me to customize the GPIO configuration when using the built-in LwIP stack. Specifically, when I try to reset or modify the configuration of one of the Ethernet GPIO pins, CubeMX disables the Ethernet interface altogether.One suggestion from a colleague was to set the CubeMX target as a raw F7 MCU, but that didn’t resolve the issue. I believe the best approach might be to manually configure the LwIP stack from scratch as a third-party library, bypassing the built-in CubeMX LwIP integration. I would appreciate your thoughts on whether this is a feasible solution, and if so, any relevant tutorials or resources on how to implement this.For testing, I have two Nucleo boards: the STM32L476RG and the STM32F767ZI. Prior to posting this, I successfully connected the built-in Ethernet module on the STM32F76

i recently made a custom board using stm32h743VIT6 and i configured lwip and freertos (before this i was using stm32f407vgt6 it is perfectly working and the circuit is same for this MCUs) now when i start the program it keeps having hardfault i tried it with MPU but still im having hardfault i changed the clock setting from external to internal but nothing changed only when i commented out MX_LWIP_Init() its working its better to mention im having only one task in freertos with 2048 stack size and also the lwip init is done completly after a little hard fault come up.my hardfault analyzer returns "Bus memory management or usage fault with bus fault details imprecise data access violation".im not having any httpd or anything on lwip i only want to get a simple ping.

Hi all,    basic info:    stm32 CUBE IDE v1.14.1    PC: Win10 64bit    MCU:STM32G0B1CC     In my code, there are two functions to control the battery to enter charge mode from init mode, when the battery receive a command. Check_AuthCmdToCHG（）will set CANOpenStruct.flag_authCmdGotoCHG to STD_TRUE and set CANOpenStruct.sendTPDOInfo STD_TRUE.    normally，after CANOpenStruct.flag_authCmdGotoCHG be set to  STD_TRUE , CheckFlag_InitGotoCHG() will make state machine FSM goes to charge mode.   But it's very strange, i send a command to MCU, then I receive TPDO info from CAN bus, this means CANOpenStruct.sendTPDOInfo already be set to STD_TRUE. however  CANOpenStruct.flag_authCmdGotoCHG and CheckFlag_InitGotoCHG() are not work!   When I examined the code, I couldn't find the cause. Therefore, I wrote a test function Test_CANCmd() ready to read CA
