Dear STM team,I am debugging the chip since hours and I think there is something wrong with the PB5 and PB15 pins:1. SPI1 with MOSI on PB5:I have configured SPI1 and want to get the SPI1_MOSI on PB5 (as mentioned as ALT5 in datasheet).I use a STM32U5A5 with LQFP64 package.Nothing comes out as MOSI (constant high, no bit pattern driven by SPI1).But:if I configure PB5 as GPIO - I can toggle - OK, no shorts on PCBI can also use the SWAP function for SPI - now MOSI comes out on PB4 (which was MISO) - all OK (SPI1 works - MOSI is now out on PB4)I can also use MOSI on PA7 - also fine!Just:PB5 is NOT a SPI1_MOSI as mentioned in datasheet!And: if I connect with SWAP configured (PB4 is MOSI) with PB5 (now as MISO): the waveform is damaged!There are not anymore nice bits out of MOSI: so, the PB5 seems to be driven all the time, with something else (see below on Remarks).2. PB15: if high - USB failsI want to use PB15 as GPIO.When I configure as GPIO and set as low (RESET pin value) - fine (USB co

Hello,I'm starting a project with an STM32F429IIT6 MCU, but I have a doubt. The project will have a display (I haven't decided yet if it will be 4.3" or 7"), and I'll be controlling the display with the MCU's internal TFT controller using TouchGFX. So far, so good. The issue is that the device needs to be able to capture a screenshot of the screen and save it to an internal microSD. Is this possible, or should I use an external driver to achieve this?Best Regards,                                                                                                                                                       

  Hi everyone.There is a my page. I defined a virtual function there. And I changed the image's location. But I can not call this function from C. I research many example but can not arrive the success. otherPageView.hpp #ifndef OTHERPAGEVIEW_HPP #define OTHERPAGEVIEW_HPP #include <gui_generated/otherpage_screen/otherPageViewBase.hpp> #include <gui/otherpage_screen/otherPagePresenter.hpp> class otherPageView : public otherPageViewBase { public: otherPageView(); virtual ~otherPageView() {} virtual void setupScreen(); virtual void tearDownScreen(); virtual void handleTickEvent(); virtual void function1(); protected: }; #endif // OTHERPAGEVIEW_HPP   otherPageView.cpp #include <gui/otherpage_screen/otherPageView.hpp> #include <touchgfx/Color.hpp> #include <texts/TextKeysAndLanguages.hpp> #include <math.h> #include <touchgfx/hal/OSWrappers.hpp> extern "C" void call_C_f(otherPageView* u) // wrapper

Reproduction steps:Open STM32CubeIDE. “File” menu → “New” → “STM32 Project”.Switch to the “Board Selector”, and pick the NUCLEO-H503RB. Click “Next”.I've successfully reproduced this issue with the NUCLEO-H503RB and NUCLEO-H563ZI. I suspect it applies equally to every board or MCU part with I3C support.Give the project a unique name – I'm using “broken-mx”. Target the C language, an executable binary, and an STM32Cube project.Pick firmware package V1.1.1. Ensure the code generator is configured to “Copy only the necessary library files”. Click “Finish”.This issue can also be reproduced with firmware package V1.1.0. It's an STM32CubeMX problem, not a problem with the firmware package.When asked whether I wanted to “Initialize all peripherals with their default Mode ?”, I picked “Yes”.This issue can also be reproduced without default peripheral initialization. It just requires a couple more clicks as you'll have to acknowledge that the icache is disabled every time you generate code.The

The Ethernet peripheral is missing from the STM32H5 in STM32CubeMX 6.10!It appears if the Nucleo or Discovery kit boards are selected as the starting point for a project, but if the project is started from a device selection the Ethernet peripheral is completely missing.First noticed on STM32H573VI, then checked it is also missing on STM32H563ZI even though this is exactly the same device as used on the Nucleo board!If I create a project using the Nucleo board then edit the .ioc file to changeboard=NUCLEO-H563ZIboardIOC=truetoboard=customthen when I open the project the Ethernet peripheral is there, but the project is based on the device not the Nucleo board!Without this being fixed, STM32CubeMX is useless for our application :(

Hi.Problem:stm32h5_xx_hal_conf.h is generated with #define HAL_USART_MODULE_ENABLED but the file stm32h5xx_hal_usart.h is not included in the project code generation.I'm using one usart peripheral in asynchronous mode, it is OK to just comment out the row in stm32h5_xx_hal_conf.h to make the project compile and work, I must do that each time the .ioc changes.Versions:STM32CubeIDE version 1.14.0STM32CubeMX version: 6.10.0-RC9STM32Cube FW_H5 V1.1.1Settings:Peripherals initialized as a pair of '.c/.h' files per peripheral 

Hello, I am looking to get hold of the SET cross-section data for 54VCXH163245 if it exists? 

I am using stm32f103rct6 controller board. I am not getting fixed ADC values for POT. I was used poll for conversion in ADC. Please attach code to get a fixed ADC value or else please address me for how to solve the problem.

Working with a STM32F426G-DISCO evaluation board and trying to get the Audio Playback application example to run properly.  Using the V1.17.1 firmware repository downloaded from ST with the Keil toolchain to build the project which builds with no warning or errors.  When I load the image onto the board it starts up as expected, but seems to hang after putting up the message “LUN #0:” on the display.  I have tried a variety of USB memory devices of various sizes and manufacturers with the same results so I believe I have eliminated that as a possible cause.  Using the debugger the application appears to be stuck in the USBH_MSC_Process function (line #363 in usbh_msc.c file) in the MSC_READ_INQUIRY state where the USBH_MSC_SCSI_Inquiry function always returns a BUSY status which prevents the state machine from advancing.  Hoping someone else has observed this same behavior and can guide me to a solution.  I did some stepping thru the code to try to fig

hello,trying to write to a ST25DV tag mailbox, via I2C with DMA.The chip has a mailbox of 256 bytes.I use  the function:HAL_I2C_Mem_Write_DMA  When I try to write data of size 256 bytes, only 255 is written and the last one is written to 0.Writing 255 bytes works fine.  Writing without DMA fixes the issue:  HAL_I2C_Mem_Write    

Dear Team,I am interfacing Nucleo-h743zi2 board  with LCM display(GUI) through UART using Interrupt method.I can transmit the data to LCM and it is displaying properly on the LCM display.Now I am trying to send the commands from LCM display to STM controller.  I tried to press the button for many times on LCM display and observed sometimes it is triggering and sometimes not triggered). I think there is a  problem with synchronisation for receiving from LCM display to STM controller. I can see the events are triggered sometimes in debugging steps.I tried to change the system clock to different values but it did not worked. Also I tried to increase the delays, decreasing delays at different places did not worked.I tried to copy the receiving buffer into the other buffer and cleared the buffer. But this also does not worked.Please find the below Receive function for your reference: extern uint8_t data_u[100];uint8 j, max; uint8 ReadSerialByte( uint8 *data){&n

Hello,i am trying to interface 1.8 inch SPI TFT Display 128 x 160 to the STM32F103C8 using SPI2.https://www.az-delivery.de/products/1-8-zoll-spi-tft-displaySPI1 is used for LoRa, i thought to connect TFT too to SPI1 using addresses but i am affraid to influence theLoRa.The library which i am using is from this website:https://controllerstech.com/st7735-1-8-tft-display-with-stm32/A year earlier i tried to interface LoRa to STM32F103C8 using SPI2 but without success.Is it a general problem in STM32F103C8 using SPI2?Any help is appreciated.

Hello:I have external sdram on FMC bus. I initialized with bootloader, mapped sdram to Bank2(0xD000 0000), and jumped to APP to run. The configuration of my APP is shown in the figure.I find that the more ram is used in the APP, the longer it takes for bootloader to jump to the app.The speed is about 1.1MB/s.However, when I ran the read and write tests in bootloader（sdram）, it took about a few hundred milliseconds to write all of them,Why is this?

  Hello, I am trying to control two Motor Drivers (TMC5041) through SPI communication using STM32F103. The compiler uses IAR. I am trying to communicate with two SPI Masters, but perhaps due to an initial configuration issue, only one SPI is controlled, so I am posting this to ask for help. ​ The current progress was controllable when each SPI2 and SPI3 were controlled one by one. For example, control is possible when TMC5041 Motor Driver 1 is controlled without defining SPI2. Controllable when controlling TMC5041 Motor Driver 2 without defining SPI3 Therefore, it is judged that there is no problem with the communication protocol with each TMC5041. ​ Here, when I try to use two SPIs 2 and 3 together, I am experiencing the problem that only one of the two SPIs can communicate and one is not communicating. In the process of specifying the initial configuration of two SPIs and sending and reading the data specified for each SPI, one SPI was able to write and read witho

HiI'm implemented the most simple pwm generation and using interruptions in F401RE with TIM1. But a delay has been in the PWM generation and the update event interrupt (underflow and overflow) the most large pulse is the PWM and the another the when interrupt occours. I tested in diferent frequencys and in another timer and the error persists.Above has my code, i want centralize the interruption in the middle of pwm pulse.Thanks.

STM32CubeIDE 1.12STM32G0B0RE microWe have an older Cube project from a STM32F0 series that needs to be changed to the larger STM32G0B0 chip. We thought that we would just create a new project with the new micro and port in the older code. When we create the new project there does not appear anywhere in the selection process to have it use the Low Level drivers instead of the HAL.Start New STM32 ProjectUnder MCU/MPU selector, Select STM32G0B0RET6Nothing in this tab has anything to do with LL drivers.Select Next.Name Project, C++ Target Language and STM23Cube Project Type.Select Next.Select 1.6.1 Firmware package.Code Generation Options does not show anything about HAL or LL drivers.Select Finish.A project has been created where the Drivers directoy has a STM32G0xx_HAL_Drivers directory. Is there any way to have project creation use Low Level Drivers?Thanks.

Hello Dear all, I want to run my STM32L452ret6 with 1.8V and use SDMMC1 module. I can use SDMMC1 with 3.3V and 50k pull ups without problems, but when I run the MCU with 1.8V and use TXB0104RGY for shifting voltaghe to 3.3 it dose not work as expected.  Which component to use for shifting SDMMC1 signals from 1.8V to 3.3V? Can I set pull up resistors with 50k valu to 3.3V but run 1.8V from mcu ? Regards, Hakob

Hi,The ADC test has only 2 channels: Vrefint and TempSensor. The following ADC result (convertedData) is read out through DMA:tick = 1s - convertedData[0] = 113968573 convertedData[1] = 0 tick = 2s - convertedData[0] = 113837503 convertedData[1] = 0 tick = 3s - convertedData[0] = 96339657 convertedData[1] = 0 tick = 4s - convertedData[0] = 113837502 convertedData[1] = 0 tick = 5s - convertedData[0] = 113837503 convertedData[1] = 0 tick = 6s - convertedData[0] = 96405193 convertedData[1] = 0 tick = 7s - convertedData[0] = 113837503 convertedData[1] = 0 tick = 8s - convertedData[0] = 113837502 convertedData[1] = 0 tick = 9s - convertedData[0] = 96405192 convertedData[1] = 0  Where convertedData[0] is the ADC reading of Vrefint which should be 4095, the other is that of TempSensor which should not be 0.The ADC configuration:The code: /* USER CODE BEGIN 2 */ HAL_ADCEx_Calibration_Start(&hadc1); HAL_ADC_Start_DMA(&hadc1, convertedData, 2); HAL_Delay(1); startTic

Hello to everyone,I have crereated my own STM32L452 board with battery power supply.It dosent run as expected. Sometimes I need to discharge caps and sometimes this is not helping. When it works and I connect nreset to groung and release it stops working, I need to powewr off and repeat mentioned process. I can flashe the code but have a problem with online debbuging (ususaly I louse connection). Somtimes it stops working when the process reaches to delays. When it works in DP port voltaghe level is low and when it not working this pin is high. I have disconnected NRESET pin from board and this is not helping.I have attaced the footprint of my board (mcu part).What to do ?

Hello!I have never used a Jetson Nano before and am rather unfamiliar with lower level programming. I have a VL53L4CX attached to the correct Jetson nano pins and can see the device when I run i2cdetect -r -y 1 at address 0x29. My question is whats next. I've done a lot of research online and have no idea how to incorporate this into an actual program that reads the distance detected by the sensor. The goal of the project is to attach 8 of these sensors to a MUX and then get data from all of them by changing i2c ports. I have seen posts referring to the linux driver, which I have downloaded but don't know how to install or use. I have a python program that sends bytes over i2c, is it as simple as sending a specific message over i2c and then reading a response? If so, what is that message?

Hi, is there support of azure rtos for stm32h5 devices?I am looking for a MCU with ethernet and azure rtos support. I have fond some examples for sym32h7 devices but those are too big. Smallest is 100pins and they are more expensive. The smallest and cheapest seems to be stm32h5 series, but when I open package manager in cube ide X-CUBE-AZURE-H5 is not there.Is it not supported or I am missing something?
