STM32 MCUs

Hi,I am currently working with the STM32C091CBT6 microcontroller and am looking for suitable development hardware.My primary questions are:Is there an official STM32 Discovery kit or Nucleo board specifically designed for the STM32C091CBT6 microcontroller? If so, could you please provide the part number or a link to its product page?If a dedicated development board for the STM32C091CBT6 is not available, what is the recommended approach for using the NUCLEO-C092RC board with the STM32C091CBT6 microcontroller? Specifically, I am interested in understanding: * Are the pinouts compatible enough for direct connection or would an adapter be necessary? Thank you for your time and assistance with this matter. I look forward to your guidance.

Title edited to be less confusing.Sorry for the confusing title. Basically what I want to do is, I have an STM32F746G-DISCO, I made a screen with 6 toggle buttons, when the toggle buttons are toggled on, the controller should give a trigger as long as the button is turned on, however, I want these buttons to automatically turn off at 8 PM (GMT+3), my main concern is creating a trigger from these buttons (preferably from the Arduino pins) and also keeping track of the time and closing the toggle buttons.The idea is that each button will be connected to the power source of a machine which will only give power as long as the button turned is on from the microcontroller screen while also turning them off so they don't get turned on outside of work hours, kind of like a switch to turn on a light bulb

when i click the ffmpeg.exe with my computer win10 system, it can't run and flick to cancel , how to solve this issue ？    

Hi,I want to generate a timeslot control signal consisting of one 10-microsecond pulse followed by fifteen 2-microsecond pulses.I want the period to remain constant, aligned on the falling edge.My problem is that before and after the long pulse, the period changes, and I don’t know how to fix it.I have:instead of:

 Hello all,I'm working with the STM32N6 series and I'm trying to correctly configure the isolation between the secure and non-secure domains using the RIF (Runtime Isolation Framework).I found example code like this in a template (STM32CubeN6)  static void SystemIsolation_Config(void) { /* USER CODE BEGIN RIF_Init 0 */ /* USER CODE END RIF_Init 0 */ /* set all required IPs as secure privileged */ __HAL_RCC_RIFSC_CLK_ENABLE(); RIMC_MasterConfig_t RIMC_master = {0}; RIMC_master.MasterCID = RIF_CID_1; RIMC_master.SecPriv = RIF_ATTRIBUTE_SEC | RIF_ATTRIBUTE_PRIV; /*RIMC configuration*/ HAL_RIF_RIMC_ConfigMasterAttributes(RIF_MASTER_INDEX_ETH1, &RIMC_master); /*RISUP configuration*/ HAL_RIF_RISC_SetSlaveSecureAttributes(RIF_RISC_PERIPH_INDEX_ADC12 , RIF_ATTRIBUTE_SEC | RIF_ATTRIBUTE_NPRIV); HAL_RIF_RISC_SetSlaveSecureAttributes(RIF_R

Hey everyone, for those who haven't seen the announcement in the community blog, I'm also announcing this here :) We're launching a contest focused on custom containers!  

Hi,We are using the OTA BLE example as the base for our bootloader on a STM32WB55.I'm reading through AN5247, and it describes the advertising message as follows:But the advertising message that I get has all its Feature Group B bits set to 0.

Hi,I'm confused about the maximum data transfer of the STM32H723ZG. The overview says:2×16-bit ADC, up to 3.6 MSPS in 16-bit: up to 18 channels and 7.2 MSPS in double-interleaved modeThen the 'AN5354 -  Getting started with the STM32H7 Series MCU 16-bit ADC' also mentions these data rates for the H7 series but not specifically the STM32H723ZG. This application note also specifies a huge discrepancy between different packages and rates:Then, assuming these numbers correspond to the direct channels, what are the data rates for the fast or even slow channels? &n

Hi,I know this question have been asked many times but i still can find a solid answer that can really help.I will try to ask again depends on the progress i have made and i hope if someone made this class that he could help.My objective is to be able to print 1 label using stm32f407 and a label printer from brother just to check the feasibility of this usb host and printer setup, so i just wanted to create usb host CDC project and adopt it to work with printer, ST community recommended this approach or use MSC.what did few changes on the usbh_cdc source and header files like this: /*Communication Class codes*/ #define USB_CDC_CLASS 0x07U #define COMMUNICATION_INTERFACE_CLASS_CODE 0x07U /*Data Interface Class Codes*/ #define DATA_INTERFACE_CLASS_CODE 0x07U /*Communication sub class codes*/ #define RESERVED 0xFFU #define DIRECT_LINE_CONTROL_MODEL 0x01U #define ABSTRACT_CONTROL_MODEL 0xFFU #define TELEPHONE_CO

Hi,I have the stm32c071 and I am running with TinyUSB 18.0 on it using CDC profile. Seems to work nicely but perhaps one in a 1000 IN transmissions the endpoint is re-activated out of the blue. Can't see that TinyUSB is doing something to make this happen (unless I have overlooked something) so my question is whether anyone has seen this behavior? I am trying to find out if this is a SW or a HW issue, and since I haven't been able to spot anything in TinyUSB I am now reaching out to hear if anyone has some information/knowledge that could help find the root cause. At the moment I can get by by setting the COUNT_TX value to 0 in the endpoint register after each transmission. The endpoint ought to have remained in NAK state as no call has been made to initiate a new transmission, and since I don't like to go about changing code without having properly identified the cause I am hoping the someone can help me getting the bottom of this.Kind regards,Christian

Hi Guys,I am planning to start a project where I require BLE and Zigbee dynamic concurrency. After going through the datasheet OF STM32WB55, under dynamic application section, I could see that the mcu acts as either BLE Peripheral/ Zigbee Router.(Also I'm attaching an image of this)Is this dynamic concurrency possible for BLE Central/Zigbee Coordinator, as in my project, my device should control both BLE and Zigbee devices.Thank You

Dear STM32 Community,I'm currently working on a bare-metal project with the STM32H723VG using the LwIP stack. I've implemented a TCP Echo Server based on the examples provided in the STM32Cube repository.The application works as expected when I open a new socket connection from my PC for each request—i.e., I send a message, receive the correct 193-byte response, and then close the socket.However, if I maintain a persistent socket connection and send multiple messages (without closing the connection), I begin to encounter an issue: after approximately 30 successful requests, the server starts responding with only partial data—typically between 5 and 30 bytes instead of the full 193 bytes. If I then close and reopen the socket, the server resumes responding correctly for another 30 or so requests.I've verified that socket creation and teardown are functioning correctly on both the client and server si

Greetings,We're a small team designing a board around the STM32N6 and need a large external memory (e.g. 64MB of SDRAM). Due to the complexity of routing and configuring timings I wonder if there exists a reference design for such a circuit, or at least for another MCU that's sufficiently similar that we can use it as a starting point. Any guidance would be very much appreciated.Regards,OV

I have created several projects in TouchGFX Designer v4.22.1 - each with a unique 'Application Name'. I'm using the STM32H747i-DISCO boards (dual-core MCU). When I import any of these into CubeIDE v1.13.2, they always show up with this type of structure in CubeIDE:STM32H747I-DISCO  (in STM32CubeIDE)  > Application  > Drivers  > STM32H747I-DISCO_CM4  (in CM4)  > STM32H747I-DISCO_CM7  (in CM7)     STM32H747I-DISCO.iocThe problem is that CubeIDE will only allow ONE of these projects to be in its 'workspace' at any given time. The projects that were first created in CubeIDE don't have this issue. Is there a way in TouchGFX to make it such that its projects import into CubeIDE with a unique name for each?

Dear Sir/Madam,Good day~I am currently using STM32F439ZI for the purpose of developing BMS.However, the code size exceed the internal Flash capacity, which is 2MB.To address this, I intend to add an external Flash (MXIC:MX25L25645G).May I know whether the external Flash can connect to any of the six SPIs available on the STM32F439ZI?or there are specific SPIs for interfacing with external Flash?Any guidance would be appreciated.Vince

Hello, I have been stuck on this issues where I cannot get my SPI slave running on the STM32H755 to successfully do full duplex communication. Right now I want the simplest case to work where the SPI master, also an STM32H755, sends a 16 bit data payload with a 16 bit attached CRC (so 4 byte total SPI frame) on the MOSI line. For simplicity, I am trying to send 0x5555 on the 16 bit data payload on the SPI slave over MISO with the HAL_SPI_TransmitReceive_DMA() function. For now I am ignoring the received data. Right now I have the SPI master successfully sending a dummy 16 bit data at 100 Hz. The problem is that the SPI slave is failing to send anything over MISO. From debugging it seems the issue is with using DMA. On the first call to HAL_SPI_TransmitReceive_DMA() i go into the SPI error callback and i get HAL_SPI_ERROR_DMA from HAL_SPI_GetError(). On the second call, I get an SPI error c

Hi Community,I'm currently facing an issue where NetXDuo with the STM32H563 locks itself out if the packet pool runs out of packets. In the current szenario the problem occurs when using the ftp-server addon and retriving  a file. As the chunks are posted to the tcp stack very fast, the socket_send routine returns success, but packets are not released (as they are currently not sent by the stack -> normal behaviour)But if this happens to fast, the packet pool runs empty (which may also be an ok behaviour here). But then the network driver can't fill up it's rx-descriptors anymore and locks up completely. The packets are never released and a reboot of the device is necessary.Is this a known issue somwhere? Any Ideas how/ where to debug further?

Has anyone successfully used this Simulink STM32 guide to write to an SD card? I am trying to run a simulink model on a Nucleo-F767ZI and write the output to an SD card. I have tried to follow the directions, but it is not working. The model can compile and run on the board, but when I check the SD card, it is still empty. I have tried different clock speeds, 1-bit and 4-bit modes, but nothing seems to work. I scoped the clock signal, and it seems to be at 400 kHz, which is indicative of it being in the initialization stage. Does anyone know what may be wrong? Thanks!  

Hey everyone,I want to use a STM32F767ZI to develop driving safety functions for electric scooters.The functions and Code are developed on Simulink using the Support Package for nucleo boards. I would like to log data from the MCU directly to a SD-Card or something similar. Does somebody know an approach to do this? One way would be to use a SD-Card via SPI, but I do not know if that is possible within the Simulink support package. I would be glad if somebody has done something similar or could give me advice how I could reach my goal.Thank's in advance!

 Hi, I need to read 8 channels through the ADC in DMA circular mode, to check the channel status readd I put all channel to GND from nucleo board and two channels (ADC_IN2 on PA2 pin and ADC_IN3 on PA3 pin ) doesn't give me the correct data, you can see in the image all channels to 0 except this two.I try change the wires but isn't the problem.All code is generated from MX tool. 

I have created a scroll list object in TouchGFX Designer. The Scroll List takes a custom container as item. I have 3 items in my scroll listFor some reason, when I call languageSelectorScrollListItems.getNumberOfDrawables(); it returns 5Checking the member declaration I'm seeing that it is defined as an array with 5 itemstouchgfx::DrawableListItems<languageItem, 5> languageSelectorScrollListItems; Why is that?

ST-LINK part's LED (LD1) on your STM32f446re Nucleo board appears dim and differently when in debug mode. but in normal, it glow normally and when code upload, it blinks.

Hello there, I see in the datasheet for the STM32C071Rx that the version N (with VDDIO) marks PD4 as supplied by the pin VDDIO in the figure 10:But the table 12 doesn't marks it as a pin supplied by VDDIO but VDD instead:

Hi,I'm working on an STM32F303RE project.So far, only the UART and TIM3 are working properly.I successfully configured TIM3 in PWM mode on 3 channels, and everything runs as expected.

Hello friends, Hardware DetailsMCU: STM32N657Z0H3QConfiguration: Custom PCB designBoot Mode: Attempting USB Boot (BOOT0=HIGH, BOOT1=LOW)Power: 1.8V system, SMPS for CORE (as per datasheet)Problem DescriptionI've designed a custom PCB using the STM32N657Z0H3Q and I'm facing issues getting it to enter boot mode. When I connect the board to my PC with BOOT0 pulled HIGH and BOOT1 pulled LOW, the USB device is not recognized by STM32CubeProgrammer.I've verified all power rails are providing the correct voltages. I've also tried multiple cables and USB ports to rule out simple connectivity issues.Additionally, I attempted using ST-LINK for programming but that's failing as well, which makes me suspect there might be a fundamental issue with my circuit design.What I've TriedConfirmed all power supplies are providing expected voltagesVerified boot pin configurations (BOOT0=HIGH, BOOT1=LOW)Tr
