Solved

This is probably an old hat to most of you here but I'm facing this problem momentarily:Using an STM32F103CBT6 (Blue Pill) where GPIOB Port is used already with the following PB3 - SPI1_SCKPB5 - SP1_MOSIPB6 - Some Interface Function (OUTPUT)PB7 - Some Interface Function (OUTPUT)   I want to use PB0, PB1, PB4, PB8, PB12,PB13,PB14,PB15 for a keyboard matrix scan and outputa running pattern to these pins. Writing the bits should be nondestructive what the remaining bits is concerned. At the back of my mind I recall something like BSRR, but could someone help me to get on the right track?I'm using HAL in this app (under STM32CubeIDE).

Hi, I am working with the SBSFU_Boot on the STM32U5A9 chip. After the SBSFU_Loader has written the update image into internal memory, a reset happens in order for the SBSFU_Boot to write the image to be booted. When performing the update, it ends up in a process where it has to do some encryption. The SAES engine is initialized successfully, and then AES_Encrypt is called. This keeps on failing because a read error is reported in the SAES->SR reports a read error upon enabling the SAES peripheral. It should be noted that the initialization and encryption sequence is strictly followed per instructions in RM0456 Rev 6 sections 50.4.4 (Initialization of SAES) and 50.4.8 (ECB/CBC encryption sequence) respectively. What am I missing?

@FBL Can you explain me about buffer descriptor table (BDT)? Is it fixed?I have got behavior that I can't explain.Dumping packets on host I got wrong data. Length is ok, but data is wrong.In BDT I wrote correct address and length. Data wrote in pma (adress that is in BDT) is correct.But when I stop in debugging address in BDT is changed. As I think in BDT there is a place for each endpoint (or it is like cyclic buffer?)What I found if I set break point with "if" condition, just before sending address in BDT is OK, and data on host is OK. It seems to me that I am working incorrectly with BDT.

Split from WiFi or WiFi+BT modules architecture and parts recommendations as that's really a separate question!Thank you @Andrew Neil I didn’t explain myself very clearly. The part I’m mainly interested in is the audio side — specifically, a microcontroller with some kind of audio I/O capability, such as microphone input and speaker output, for recording (and then saving to uSD - perhaps using DMA if it makes sense). I’ve never worked with microcontrollers for audio recording before, so if such micro is not available, I’m also open to a low-cost solution/architecture that uses external components.Thank you

The ST1S06xx datasheet (https://www.st.com/resource/en/datasheet/st1s06.pdf) contains an error: Figure 10 "Input voltave vs output voltage" has the axes labels swapped:A correct version of the Input voltage vs output voltage characteristic can be found in figure 7 of Application Note 2371 https://www.st.com/resource/en/application_note/an2371-st1s06-high-frequency-synchronous-buck-converter-stmicroelectronics.pdf : The datasheet is also missing details on a crucial characteristic: output voltage vs current. In my circuit I have R1=18k, R2=5.6k. Nominal output should be Vout = 0.8V*(1+18/5.6). With a load of 600mA I measure Vout = 3.36V; increasing the load to 800mA, Vout = 3.16V. Another crucial characteristic that's missing detail is dropout voltage: the only indication is figure 11 mentioned above, which suggest for a 1.2V / 1.5A output the dropout voltage is approx 1.1V, but there's no indication of how that changes with input/output voltage or current.

(I tried to submit a ticket but the system seems broken, giving an obscure error about an incorrect zip code).I need to confirm which version of STM32 is placed on a board. There are two versions, GP and PD. The datasheet does not really specify how the top marking is different for the two versions.    Any ideas?Thanks, Pete

I have a project that is using custom hardware with a STM32G0B1CBT6 processor.  The code is developed using STM32CubeIDE and STM32CubeMX.  However, there are times when I am unable to run a debug session and I'm seeing (very) occasional Hard Faults.I have a diagnostic serial port and have successfully modified my Hard Fault Handler to dump additional information out that port.So what I'm after is some code that can read registers and/or the stack to provide additional information that I can use (along with the map file, etc) to determine where my Hard Fault is happening.Can anyone point me in the right direction?  All my searches have shown me code that references registers I can't seem to find in the docs.Thanks.  

Hi,I am setting up SBSFU on our STM32H750. I want to test the RDP and WRP security protections.Steps taken so far:I have enabled WRP and RDP Level 1 by setting the option bytes through cubeprogrammer and enabling SFU_WRP_PROTECT_ENABLE & SFU_RDP_PROTECT_ENABLE in app_sfu.hI have enabled SFU_TEST_PROTECTION in app_sfu.h Note:There are several test cases in sfu_test.c that I am using. The tests in questions are attached below:TEST_ERASE_FLASH is failing.  Output:I am not sure why this would be. Does anyone have any advice? 

Hi everyone,I’m currently working with the CR95HF and looking into using the provided DLL (CR95HF.dll) for PC-side communication.From the documentation and software packages I understand that a DLL is provided to interface with the CR95HF demonstration board (). However, it seems this DLL was originally built for older environments and is typically installed in x32 systems, which suggests it may be a 32-bit library.I searched the community and found a previous discussion where someone asked about x64 compatibility ( Solved: CR95HF DLL for x64 - STMicroelectronics Community ) and was provided with source code instead of a precompiled DLL.So my questions are:Is there now an official x64-compatible version of the CR95HF DLL available?Or is the recommended approach still to request/use the source code and rebuild the DLL for x64 systems?If rebuilding is required:Is there any official guidance or updated project for generating a 64-bit version?Thanks in advance for your help!

Hello , i would like to know how can we set the pwm channels in stm32cubemx as well as the serial wire debug , because i want to set up a project with  STM32C5A3RGT6 but under the debug we have no 2 wire serial wire debug option. Edit: Moved from Introducing STM32CubeMX2, a new flavor of STM32CubeMX tool

Hello,I have two technical questions regarding the lis3dh accelerometer behavior and interrupt configuration.1) Are the values I read from the LIS3dh  in m/s²????  Exemple :::Accel [LIS3dh] 28807220458ns (-7.300384, -1.942303, -5.712095)2) Interrupt logic (INT1_CFG :: XLIE / YLIE / ZLIE)When I configure an interrupt threshold, for example 5 m/s², and enable the axis event bits in INT1_CFG XLIE / YLIE / ZLIEDo the Low events correspond to the following type of comparison?X < threshold, Y < threshold, Z < thresholdOr do they correspond to:|X| < threshold, |Y| < threshold, |Z| < thresholdFor instance, if I have the following measured values and the interrupt threshold is set to 5 m/s²:Would this condition trigger an interrupt or not, according to the configured AOI ,XLIE / YLIE / ZLIE  (i put 1 for this register)???Accel [LIS3DH] 29380340576ns (-18.442175, -19.566559, -19.461311)Thanks for your response  

Hi,I am using IIS2ICLX MEMS accelerometer in an IOT device.The IIS2ICLX is soldered on a PCB that sends data to internet every 10min.To measure the zero-g level of both x and y axis, I suspend the device from the ceiling so that the PCB (and the accelerometer) is perfectly horizontal and and vibration-free.I noticed that the zero-g level changes if I briefly touch the device, and wait for the device to return to its horizontal position (the temperature of the device does not change).Does anyone has an explanation ? I there a way to minimize this effect by using two redondant accelerometers, with a 90 degre rotation between them ?Thanks for your help.

Hi. I have been looking at the internal operation of MEMS devices and am looking for information on how this sensor takes the reading from the mechanical parts. I am trying to find out if this sensor uses capacitive sensing or frequency drift and time period for one sample to be acquired from the MEMS structure. The available documentation does not list much information of this and any additional information would be great. Thanks.

Hello everyone. I would really appreciate if someone could help me sort out a really annoying issue i have with a new STM32WB5MMGH6 based board i made.On this board i have two sensors connected to the same SPI interface (hspi2) with different CS pins to address the sensors. Here's the schematic sections of the two sensors : MS5607 :  LSM6DSV320XTR with an auxiliary IIS2MDCTR tied directly to it (for the test board, the magnetometer is not soldered yet):I'm currently on test phase, and the MS5607 is responding correctly. But the LSM6DSV320XTR does not respond at all. i'm not even getting the whoami ID (i get a 0).For the SPI configuration i have this : For the 2 Chip Select pins i have this config :   I don't understand where the problem comes from. Could someone help me asap ? I'm losing hope :(

Question split from this thread. Hi ,  Can you also provide some info on how to set pwm through timer channels ?

Hello ,   I was planning on using the new STM32C5A3RGT6 for my new project but after reading the comments regarding the stm32cubemx2 , i am reconsidering this decision. I also saw that zephyr is providing support for stm32c5.    My question would be then what would be a good source for learning stm32cubemx2 because coming from stm32cubeide 1.17 it is a big change.

Hello,STM32CubeIDE.Is it possible to show hints (description of the function, description of the parameters of the function, description of the return value) when calling function?I made this function (see Figure 1) and made documenting comment. When I calling this function or I hover the cursor over the function name a tooltip with the function code pops up, but I want to see description of the function (@brief parameter from documenting comment, see Figure 1).Figure 1 

hello ST Community, I'm trying to send commands as indicated in the AN3155 manual via UART with Teraterm on the NUCLEO-H755ZI-Q for CM7. system bootloader application note (AN3155)  First, I tried establishing UART communication with the STM32CubeProgrammer, and it worked while Boot0 = 1 on the USART3 pins. But I'd like to establish the same communication via UART using Teraterm serial. As soon as I set the bootloader state to Boot0 = 1, I send the command 0x7F, and I get no response on the terminal. What did I do wrong? Thanks for supports

When we provision the Secure Manager on the STM32H5 and there is no non-secure application available (yet), then the Secure-Manager-Demo-Application currently starts flashing all LEDs on the STM32H573I-DK.Now we wonder how this would affect our project-specific hardware if the provisioned Secure Manager configures some ports and starts toggling PF1, PF4, PI8 and PI9.So, what peripheral does the Secure Manager configure/use? And how are they configured?Is it possible to suppress/remove this Secure-Manager-Demo-App (SMAK_Appli)? => no port configuration, no LED togglingbr, Oliver

Hello i'm new to STM32, i'm doing school project on in. Basically the plan is to read oil temperature from CAN bus in car, and display the temperature on analog clock using servo. I have the H755ZI-Q board for this. I know it's bit overkill for what i'm doing but i'm fine with it.I've did a test code for inter core communication test. Since i want to receive the CAN info on M4. Calculate the PWM signal on M7 and then the M4 will update the PWM signal. Now it just send some numbers and displays it via uart on pc console for checking the data. But as soon as i wanted to implement the servo i started to have some issues. Basically i enabled the TIM2 with PWM generation on M4, and then the board didn't want to communicate via the STLINK. I've got error: failed to start GDB server (No device found on target). So I've erased the flash memory by bridging the BOOT0 and VDD and erasing it in CubeProgrammer. And then i have to run different project  first, before mine for it to event progra

Hi,  i'm missing something in the configuration of alternate function on STM32C092. I can't get working alternare function on shared pin, interested physical pin are  PIN 1, 15, 20.  Example1: PIN15 only the function on PA8 are working properly, neither (PB0,PB1 or PB2) are working at all with any function even a simple toggle. I'm pretty sure that the Alternate Function property are being generated correctly. Example2: PIN20 Generating a PWM with TIM3_CH1 only works on PB6, if the same timer is passed to PB4 i can't get any output. Same on PIN1 i can get output only on PB7.  There is the HAL_TIM_MspPostInit where PB6 is working as expected but PB1 isn't: void HAL_TIM_MspPostInit(TIM_HandleTypeDef* htim) { GPIO_InitTypeDef GPIO_InitStruct = {0}; if(htim->Instance==TIM3) { /* USER CODE BEGIN TIM3_MspPostInit 0 */ /* USER CODE END TIM3_MspPostInit 0 */ __HAL_RCC_GPIOB_CLK_ENABLE(); /**TIM3 GPIO Configuration PB1 ------> TIM3_CH4 PB6

I am working with STM32F746G-DISCO development board for my phasor measurement unit project. The project displays few line parameter and a phasor diagram with a GUI and also sends data to a network.The project was first created with TouchGFX with all the GUI created and working standalone but when LwIP and ETH is enabled using the CubeMX the display does not work. The display has artifacts and also the other parts of the programme does not work.Please help me out to know what is the proper way of creating a project which uses TouchGFX for GUI and LwIP.  I am pretty sure that it is a memory conflict. Both LwIP and TouchGFX using the same memory region. But even after doing some MPU configuration and changing the framebuffer start address, the problem exists.I have attached the .map file of the project as .txt file for the better understanding.

Hey there,I'm currently trying to port a project that I was using successfully on the STM32U5A5, to the STM32N657.The project utilises the PDM2PCM library to convert a PDM audio stream received from a MEMS microphone via the SAI interface of the MCU into PCM audio data. It is based on an example from the STM32U3 MCU firmware package (STM32Cube/Repository/STM32Cube_FW_U3_V1.3.0/Projects/NUCLEO-U385RG-Q/Examples/SAI/SAI_AudioRecord_PDM), parts of which I have incorporated into my own application on the STM32U5A5.I'm now trying to port this project to the STM32N657 on a NUCLEO-N657X0-Q board. I've found the matching PDM2PCM library for the N6's M55 core in the X-CUBE-AUDIO-KIT as mentioned here.Now, when I integrate this library (libPDMFilter_CM55_GCC_wc32.a) into my project and start the debugger of the STM32CubeIDE it starts printing "Target is not responding, retrying..." in the debugging console as soon as the program flow reaches the call to the PDM2PCM_init function of the libr

Dear ST We are currently proceeding with development using the STM32H743VGT6.As you can see in the datasheet, the STM32H743VGT6 has a built-in 1M flash.I confirmed that it operates normally even though the flash partition was divided as shown below for the FOTA function.and Confirmed normal operation of arbitrary 0xFFFF0F0 Write/Read at address 0x8140030 in the Storage area. Therefore, to check if the MCU with 2MB Flash was incorrectly mounted on the PCB, I disassembled the device and examined the STM MCU part number under a microscope, confirming that it is an STM32H743VGT6 as shown in the figure belowAnd by referring to the RM04033 reference manual and reading the flash size as shown below, I confirmed that it has 1MB of Flash.The register values ​​and product name on the STM32H743VGT6 appear to indicate a 1MB FLASH, so I am wondering why READ & WRITE to the FLASH is working normally even in areas exceeding 1MBThanksBRMr.shim
