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 using X-CUBE-AWS-H7S (v1.0.0) on a STM32H7S78-DK.The bootloader and app were built directly from the package with no source code changes at all, yet the UART-based CLI shows that the board is reset every now and then (sometimes every ~5 minutes,...
Hi Everyone,I have written a firmware which write some meta data in STM32L4 internal flash memory. But sometimes it happens that code gets stuck in a loop while erasing the flash memory. uint32_t UserFunctionForErasingFlash(void) { FLASH_EraseInitT...
Hi.I was working on my small pet-project, trying to develop USB mic on my stm32f4 discovery board. I was successfully completed this project but still not fully understand how it`s working. Function DCD_EP_Flush really confuse me.My device work as fo...
Hello everyone,I'm working on a project using the STM32F334R8 MCU to capture two rising edge signals with the intent of obtaining the CNT value at each signal's rising edge. My calculations and data are meant to be processed through an external inte...
Hi folks,I've got an F429ZI board which works fine, I've run a few samples and I've had zephyr applications running on it no problem. What I now want to do is set up my own small project using the bare minimum of third-party code to begin. I used Cub...
Hello everyone,My company bought a card ... We want to use the 4 bit SD card.I generated a System Workbench for STM32 project (FatFs) , without modifying anything in the GPIO, SDMMC or other properties.Compilation and programming is done without prob...
I was struggling to get LwIP TFTP server working on MCU boards (NUCELO-H743ZI). After debugging I have found:Why is TFTP_MAX_MODE_LEN defined as 7 (instead of >= 8)?Why is TFTP_MAX_FILENAME_LEN just defined as 20?So, it results in:sending (PUT) or re...
using stm32h753bitx controller and their latest HAL drivers. On the every reset RTC loses one second. It also loses time while the device in idle condition.My devices uses main battery power and coin cell battery for backup.Here's my RTC initializati...
I am trying to get the PCM1808 ADC working on my STM32H7 using Cube IDE, but get stuck regarding endianness.I understood STM32 is little endian and i2s is big endian. I am trying to receive 24 bit data via DMA but when reading my DMA buffer I am not ...
I using the stm32L4+MT29F2G01 and the latest Filex library from ST 2.0.0 (6.2.0 AzureRTOS). After the format, the performance is satisfactory for me (250ms write 2048B), but after saving a few files of about 1MB each, the efficiency drops sharply, th...
