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...
the sample code I2C_TwoBoards_ComDMA for the STM32H563 EVB.On the host side, if the command length is unknown and may vary from one to three bytes, how can I modify the following function to handle a variable-length transfer based on I2C received siz...
Hello,I have been working on a project recently that has me using the SPI1 and 2 peripherals to perform conversion between a non-standard serial format and TCP/IP. I have SPI 1 set up as a transmit-only master which takes data received via TCP/IP and...
Hello!This function was defined and used instead of memset to reset mbedtls's sha256 context. Is there a good reason behind this choice?https://github.com/STMicroelectronics/STM32CubeH7/blob/master/Middlewares/Third_Party/mbedTLS/library/templates/ha...
I've written a flash-based bootloader for the STM32F4 using the latest STM32CubeMX tool and its HAL libraries. I've avoided all the usual pitfalls (it's not my first bootloader), and my code works reliably. I'm not erasing my bootloader segment, writ...
I'm working on RTC smooth digital calibration on an STM32U575 board using the HAL function HAL_RTCEx_SetSmoothCalib(). I'm using the LSE (32.768kHz) as the RTC clock source.What I'm trying to do:I want to adjust a known RTC drift (e.g., 500ms) over t...
Hi,I am using a NUCLEO-G071RB development board. I accidentally erased the original bootloader while flashing a custom one. Is it possible to reflash or restore the built-in bootloader on the NUCLEO-G071RB development board? If so, where can I obtain...
I am having issues when writing a buffer that is declared in the external buffer to an SD card. When I tried to download a bulk file (1.5MB), write failure (f_write returns FR_DISK_ERR) would happen at least once during the download process, but if I...
Hello,An ST employee wrote this article: https://community.st.com/t5/stm32-mcus/how-to-use-the-stm32n6-in-overdrive-mode/ta-p/810926where you can increase the voltage to the STM32 core to get higher performance. I have 3 questions regarding this art...
Hello ST Community, I’m working with the NUCLEO-H533RE. The MCU is feature-rich (three PLLs, robust comms, and onboard USB wired to a USB-C connector) and I’m running the system clock at 250 MHz. I’ve migrated the project to ThreadX (since the old US...
Hello,I'm wondering if Cube's generated code for is thread safe. In particular, whether malloc can be safely used in a multi-threaded FreeRTOS setup.The broken malloc behavior was first described by Dave Nadler in 2019 here. He has also written about...
