Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I am migrating from STM32L431 to STM32L471. After migration, the function relating to internal flash writing does not work any more. The problem is when I programmed internal flash with HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data), ...
Hello,I am trying to get the audio data from ADF1. Therefore I use the GPDMA as shown in this example: https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/STM32U575I-EV/Examples/MDF/ADF_AudioRecorder. I am developing on a B-U585I-IOT...
Hi,STM32G484 is running well with FreeRTOS.The only thing left is to transfer the USB communication into the RTOS-task.Is it possible to redirect the function pointer, which is used now, to another function?Greetings,ErX
Hello,I am implementing a USB Audio Class 1.0 microphone on an STM32 (Full-Speed only).The device enumerates correctly on Windows and appears as a 4-channel microphone in the Sound Control Panel, but no WASAPI-based application can open the input str...
Hello,I am using an STM32H743 microcontroller. UART8 is configured at a baud rate of 460800 with DMA enabled. The UART output is logged by a USB logger which creates a FAT32 text file.The transmitted data contains mixed data types such as integers, c...
I have a bunch of following warnings:c:/programs/ARMtools/EmbeddedBSPs/arm-eabi/com.sysprogs.arm.stm32/STM32F1xxxx/STM32F1xx_HAL_Driver/Inc/stm32f1xx_ll_gpio.h: In function 'void LL_GPIO_SetPinMode(GPIO_TypeDef*, uint32_t, uint32_t)': c:/programs/ARM...
Hello everyone,I am using SPI2 of STM32F103RCT6 to communicate with an AT45DB641E DataFlash device. I am trying to understand why the effective SPI data rate is significantly lower than what I expect based on the configured SPI clock.Hardware setupMC...
I would like to use the single USB internal PHY on the STM32H735 to connect to a 2 port hub chip (like the Microchip USB2422) so that I can connect to both a USB stick for firmware upgrades as well as a cellular module. I started connecting everythi...
Hello everyone,I created an external loader project using the STM32H743 development board. I used the W25Q32 chip. I used SPI directly in my project (I didn't use OctoSPI or QSPI).I followed the advice found in forums and meticulously followed the vi...
Hi, I got stuck in the HardFault_Handler every time after editing some code. I'm using FreeRTOS in c++ combination with classes. First I thought this would be a memory issue. After increasing configTOTAL_HEAP_SIZE and configMINIMAL_STACK_SIZE, I was ...
