STM32 MCUs Embedded software

HI, I'm using stm32h7s78-dk, and setup the external flash following this tutorial The "appli" project is in external flash and runs with no issue. Now I want to write some config data such as display brightness to the external flash according to user input but I can't find a way to do that. I tried HAL_FLASH_Program(), but it seems can only modify the internal flash. Then I tried to enable EXTMEM_MANAGER_APPLI in CubeMX to use EXTMEM_WriteInMappedMode(). However, I can't reinitialize the xspi in "appli" project..What is the appropriate way to do this? Any input is much appreciated!

Hello,I need to build a USB headset(mic+speaker) using STM32H742VIT6 for a project. I want the stm32h7 to be recognized as a audio device when connected to a PC/android device. Is this possible?This is my first time using a STM Board with cubeMX and cubeIDE, so I want to build the microphone part first. I am having trouble programming the board, specially what middleware to use, how the structure of the project works in the ide, what would be the setup e.g. clock config, dma, adc, timer configuration. It would be nice if I could get some resources/guide on how to start, because I am lost inside the mx and ide!Hardware: WeAct Studion STM32H742VIT6MAX4466 mic

Hi, I'm a bit stuck.   I'm trying to program watermarks for BANK2 (to make the entire bank secure so I can read the whole area using secure alias) for a custom boot-loader.   The code below is executing in secure context from BANK1 (and no bank swap).  It runs without error, but after a reset, the option bytes are still unchanged.   Im calling it with (FLASH_BANK_2, 0, 63, 0) as arguments. (63 being the last flash page of a 512KB bank - device is 1MB)   I am pretty sure I misunderstand something.   Kind Regards, Nick /**  * @brief Configures or Disables Secure Watermark for a specific bank.  * @PArambank: FLASH_BANK_1 or FLASH_BANK_2  * @PAramstart_page: Start page (Set > end_page to disable)  * @PAramend_page: End page  * @PAramlaunch: If SET, triggers a System Reset immediately to apply changes.  * @return true if the operation was successful, false otherwise  * @note to disable WM, set start_page > end_

Hello, I am experiencing a problem with ADC1 and ADC2. I configured them in Dual Regular Simultaneous Mode, where ADC1 acts as the master and ADC2 acts as the slave. The ADC channel connections are as follows: ADC1 Channel 1: 24V_Sense ADC1 Channel 2: 5V_Sense ADC2 Channel 14: IOut_Sense ADC2 Channel Vrefint: Internal reference voltage However, I noticed that IOut_Sense always has a value, while 24V_Sense is unstable and fluctuating. OUTPUT:V24:24011 mV | V5:3 mV | I:23653 mA V24:8807 mV | V5:3 mV | I:8675 mA V24:8726 mV | V5:1 mV | I:8675 mA V24:8844 mV | V5:3 mV | I:8675 mA V24:23767 mV | V5:1 mV | I:23528 mA V24:23853 mV | V5:0 mV | I:23590 mA V24:23727 mV | V5:0 mV | I:23435 mA V24:23968 mV | V5:0 mV | I:23481 mA V24:8832 mV | V5:3 mV | I:8675 mA V24:23541 mV | V5:0 mV | I:23388 mA uint32_t adc_dual_buffer[4]; int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_ADC1_Init(); MX_ADC2_Init(); MX_USART1_UART_Init(); MX_I2C1_Init();

Hi Together,I am currently trying to use the FMAC hardware accelerator. Normal usage already works. Now for numerical stability I want to implement the filter as second order sections (sos). According to RM0481:Cascaded filters must either be combined into a single stage, or implemented asseparate filters. In the latter case, multiple sets of filter coefficients can be pre-loadedinto the memory, one set per stage, and only the X2_BASE address changed to selectwhich set is used.To do this I currently:Concatenate all the stage coeffs into one vector:static int16_t const b_Coeffs_0[b_Coeff_len_0] = { 55, 111, 55 }; static int16_t const a_Coeffs_0[a_Coeff_len_0] = { -3745, -258 }; static int16_t const b_Coeffs_1[b_Coeff_len_1] = { 16384, 32767, 16384 }; ...static int16_t all_coeffs[sos_Coeff_Count] = { b_Coeffs_0[0], b_Coeffs_0[1], b_Coeffs_0[2], a_Coeffs_0[0], ...On setup input the vector as b coefficients:filter_Config.Clip = FMAC_CLIP_ENABLED; filter_Config.Filter = FMAC_FUNC_IIR_DIRECT

The image sensor inputs a 24 MHz clock and outputs a 40 MHz clock, and the captured image size is 1280×1024×2. When the trigger mode of the image sensor is enabled, the main loop execution speed slows down by approximately 1.6 seconds; when the trigger mode is disabled, the system operates normally. Furthermore, I intend to transmit the images collected by DCMI via USB, but these two modules cannot be enabled simultaneously. Additionally, when the DCMI is operating, serial port interrupts will cause abnormal operation of the DCMI. How should I resolve this issue? Below is the configuration code and main loop code of my STM32H743:

I've developed a board using an STM32F767ZI to manage a set of power supplies via PMBUS. I've connected 4 I2C buses, each with 5 slave devices (power supplies), managing a total of 20 slave devices.My application continuously polls the slave devices to get their status. When I use a single I2C peripheral, I never get any read errors. However, when multiple I2C peripherals are running simultaneously, I get bursts of read errors on all 4 buses (though not all at the same time) approximately every 30 seconds to 1 minute.Each I2C polling routine runs in a separate FreeRTOS task.I've tried using the HAL drivers I2C in Polling, IRQ, and DMA modes. I've also tried using the I2C peripherals in PMBus mode (CubeMX Setup). The bus speed is 100KHz. I tested enabling one peripheral at a time and noticed that the frequency of errors increases as the number of enabled peripherals increases (no errors with only one I2C enabled, errors every 30s/1m with 4 I2C enabled).Can anyone suggest what I should i

I am trying to establish an ethernet comms with the STM32F207ZGT6 MCU.I have configured the pinout in CubeMX and followed various online resources for implementing LWIP, however I have had no success in discovering the device on my network, and thus am unable to ping. The Link led on the ethernet port lights up after my computer is connected, but no communication is acheived. I am using a DP83848MSQ/NOPB PHY. Could someone please shed some light on the CubeMX configurations for the LWIP. I have disabled DHCP and assigned a static IP. My computer is on the same subnet (192.168.1.xxx)as assigned in CubeMX for the MCU's LWIP settings. Further, both my computer's ethernet port driver and the MCU are assigned the same netmask (255.255.255.0). The MCU and PHY are configured to operate in RMII. I am currently not using FreeRTOS. I read elsewhere in a thread that there are some bugs associated with memory allocation for the heap, alongside issues with the HAL driver, ethernetif.c and lwip.c fi

Greetings! So I have a personal project, using a STM32U585 MCU, with a self-designed board, in which I have a bootloader and the main firmware. So basically I implemented a protocol for communicating with the board, I have a C program that sends a command and the board sends data (around 20Kb), using USB.The scenario is the following: I flash the firmware with the bootloader, after flashing, the bootloader jumps into the main program and starts running, I send a command (via host) to get data and the board sends me data and everything is running smoothly. The problem starts when I unplug the board and plug it again, when I send the command to get data, the board starts to send it and then it completely freezes. Another curiosity, this situation only happens when I plug the board in a USB hub... if I plug the board directly to the laptop, I won't have any problem. Any clue of what can be the problem? Power related? Is there any issue with the jump to the main pr

I just started looking at the STM32C071 family as an alternative to the STM32F042 and STM32F072 we currently use. To my disappointment the USB stack for the C071 is a total mess (dozens of files and complete spaghetti) and on top of that it seems to be written by Microsoft. So there is absolutely no way we are going to use that.Did I miss some other option for the USB device library? This USBX stuff definitely is no option at all.At first glance it looks like there are no significant differences between the USB hardware of the C0 and F0 if only used as device not host. So I am wondering if I can simply use the F0 libraries (which we have debugged and optimized…) on the C0. Or are there any hidden traps?

Split from FATFS for STM32u575 - this is a different issue.helloo, i did the same exact thing and everything compiled properly, but after running it, the code freezes when the f_mount() function is encountered. Did you find a solution to your problem ??

I am struggling to wakeup STM32N6570-DK from standby mode with user button (WKUP3).I created an isolated CMake + VSCode test project and share it in zip file. Based on latest CubeMX 6.17.0 and STM32N6 HAL 1.3.0. There is application and FSBL but I only use FSBL and do not jump into Application. My intention is that after wake-up, MCU launches Boot ROM that launches FSBL.The core part of the code is:static void EnterStandbyMode(void) { PWREx_WakeupPinTypeDef sWKUPConfigs = {0}; /* Prevent any disturbing interrupts */ __disable_irq(); /* Enable the Wake-up pin functionality */ sWKUPConfigs.WakeUpPin = PWR_WAKEUP_PIN3; /* PC13 (User button) */ sWKUPConfigs.PinPolarity = PWR_PIN_POLARITY_HIGH; sWKUPConfigs.PinPull = PWR_PIN_PULL_DOWN; HAL_PWREx_EnableWakeUpPin(&sWKUPConfigs); HAL_PWR_ClearWakeupFlag(PWR_WAKEUP_FLAG_ALL); /* AN5946 and errata say that BSEC should be enabled to go stand-by. */ __HAL_RCC_BSEC_CLK_SLEEP_ENABLE(); __HAL_RCC_BSEC_CLK_ENABLE(); /* Set init

Hi all,I’m working on porting a firmware from a Microchip PIC18F66J50 to an STM32C071.The original device communicates successfully with Windows and Android devices over USB, through an app developed in Flutter (Android Studio) using the QuickUsb library.On the STM32 side, I’m now using the USBX stack. After quite a bit of work, I managed to get the USB communication fully working with Windows — enumeration and protocol exchange both succeed.However, while the device correctly enumerates on Android, the protocol communication fails.Since the Android app already works perfectly with the original Microchip-based device, I assume that no changes are needed on the app side. This suggests that the issue lies in how the STM32 presents itself to Android (possibly in the USB descriptors or class/interface setup).Has anyone experienced similar issues with USBX on Android, or are there known differences in how Android handles vendor-specific protocols compared to Windows? Thanks for your he

I want to be able to program the external flash via VCP. So far, I have taken the combined code from the CM4 and CM7 core, then using memory address 0x90000000, I write to the QSPI using the BSP function: if (receiving_ext_flash) { if (BSP_QSPI_Write(0, Buf, qspi_write_address, Len) != BSP_ERROR_NONE) { CDC_Transmit_FS((uint8_t*)"QSPI Write Error\r\n", strlen("QSPI Write Error\r\n")); receiving_ext_flash = 0; return; } qspi_write_address += Len; } Has anyone tried doing something like this? I have not been able to get this to work. Thanks!

Hello Everyone,I recently purchased STM32H7S78-DK.I'm looking for the code that runs on the discovery kit.As I understood from my collogue there should be an application that defines all the peripherals via cubeMX.I've downloaded the repository for this DK but all I see is examples that covers some of the peripherals and not one application that defines all the peripherals. I would if someone can share with the link for this application that define all the peripherals. 

Hello everyone, I’m working on the STM32G474RE and trying to generate two independent PWM outputs using the HRTIM peripheral. To get started, I followed this tutorial: wiki.st.com/stm32mcu/wiki/Getting_started_with_HRTIM For my first PWM output, I used: Timer: HRTIM1 Channel: CHA1 Compare Unit: CMP1 This one works perfectly , the duty cycle changes correctly when I update the compare value.   The problem When I tried to add a second PWM output, I followed the exact same steps as for the first one, except I used: Channel: CHC1 Compare Unit: still CMP1 (as shown in the tutorial) However, this second output (HRTIM1_CHC1) is always stuck at 50% duty cycle, no matter what compare value I write. Even if I set the compare value very low or very high, the output waveform stays at 0.5 duty cycle.   What I checked The GPIO pin for CHC1 is correctly configured in alternate function mode. The timer is enabled and running. The compare register is being updated (I

Dear ST Support Team,I am currently working with the STM32N657X0H3 microcontroller.We are attempting to use the internal 4.2 MB continuous SRAM (starting at address 0x34000000) as the framebuffer for LTDC.The procedure followed is:• Writing pixel data into internal SRAM at 0x34000000• Configuring LTDC_Layer1->CFBAR with the same framebuffer address• Enabling LTDC and RGB outputHowever, when using the internal SRAM (0x34000000) as the framebuffer, the RGB output signals remain inactive.When we configure the framebuffer in DTCM memory (as mentioned in the reference manual), the RGB signals become active and function as expected.However, the DTCM memory size is very small and not sufficient to hold a full framebuffer for our display resolution. Therefore, using DTCM is not a practical solution for our application.We have verified the following:• AXI read/write test passes successfully• Framebuffer base address is correctly configured• LTDC timing configuration is correct• RGB pin confi

Hello ST team,I am using Nucleo H753zi board, and I wanted to use X-CUBE-MEMSMIC1 expansion for sound source localization.I have already designed simple PCB to use MEMs microphone and connect it to H7 board's ADC. I want to understand how I can program my board to use 4 mics- GCC-PHAT algorithm to get location of sound source. I have gone through UM2212 and UM1901. Due to lack of experience in this field, can you guide me through how I can use this X-CUBE-MEMSMIC1 expansion for sound source localization? I found this diagram helpful and would like to understand how should I code to feed data from cache to Acoustic SL for processing.
