I need a second pair of eyes. I am trying to setup EXTI using the GPIO HAL. But it looks like its doing it wrong. It must be me but I need you to double check to be sure.This is STM32G0 HAL so stm32g0xx_hal_gpio.c /*--------------------- EXTI Mode Co...
Hello,I have just started with STM32 after some projects with AVR MCUs. I have recently noticed a strange behavior with "HAL_UART_Receive_IT" function. Everything works fine for me if the size argument is one, but for other values the overrun flag is...
I am currently working with the STM32H573I-DK discovery kit and am trying to enable Ethernet connectivity using LWIP in STM32CubeMX and STM32CubeIDE. However, I have noticed that the LWIP option is not available in STM32CubeMX for this board.Could yo...
Hi CommunityI can not find the " HAL manual M1785 User manual Description of STM32F0 HAL and low-layer driver" pdf file in the dedicated webpage for this product, which is the following page:https://www.st.com/en/microcontrollers-microprocessors/stm...
STM32L476RE immediately exits STOPMODE2 after entering, even though the HAL_SuspendTick() tick has been called prior to.I have a small C application running on an STM32L476RE and I am using FreeRTOS as an OS. I want to periodically enter into a low p...
Hi,I am running my Zephyr application from an OSPI external flash and would like to write to the same flash. The MCU is an STM32H730, and the flash is an IS25LP128.However, the flash_stm32_ospi_write method in zephyr/drivers/flash/flash_stm32_ospi.c ...
Meanwhile STM goes with Microsoft AZURE RTOS - ok, fine, feature rich, obvious! But "I miss a feature": open and read a file from the MCU internal flash memory (as a const file content, as array of characters, without a need for a sector based, FAT b...
Hello. I tried to initialize SDRAM (I am using STM32F746 discovery kit), but I try to run it as a separate project just for learning. However I encountered the following problem: when I read data from SDRAM in my case starting from 0xC0000000 address...
Hi, I am working on a custom project with the STM32H755ZI (Cortex-M4 core) using the SDMMC peripheral and FatFs to read from SD cards. The SD card is inserted into a slot on my custom PCB, and the SDMMC peripheral is clocked via PLL2, because of this...
Hello,I'm facing a bizarre issue with USART2 in STM32H7 chip.My H7 is connected to 8 F072 chips via UART. Communication with each chip uses a dedicated UART from 1 to 8.All the data exchanges in both RX and TX work fine during normal operativity of m...
