HAL_I2C_Mem_Read_DMA and HAL_I2C_GetState never gets HAL_I2C_STATE_READY

Hi,I use the NUCLEO-F091RC, STM32CubeIDE with the MCU Package 1.11.3 and FreeRtos.The I2C1 is used with an Eeprom. So I would like to use the function HAL_I2C_Mem_Read_DMA as it is shown for example STM32Cube_FW_F0_V1.11.3\Projects\STM32091C_EVAL\Exa...

STM32L552xx USB low speed mode?

Can STM32 USB device (ACM) be configured as a LOW SPEED device? It seems like USB SW and HW doesn't support configuring a low speed ACM device. Any help is appreciated in advance. From page 1953 of Ref. Manual:

ADC implementation with DMA in STM32G431 using LL_DMA API functions and Zephyr framework

Dear AllI am working on STM32G431 trying to implement ADC using DMA in Zephyr framework.Below is my code,#include <zephyr.h> #include <sys/printk.h> #include <drivers/adc.h> #include <stm32g4xx_ll_system.h> #include <stm32g4xx_ll_dma.h> #...

PTP clock source is SYSCLK or HCLK?

The reference manual for STM32F407 shows (RM0090) that the PTP clock is running from the SYSCLK directly, however, the PTP chapter says that it is controlled by the HCLK. I'm confused now, and experiments show that it is running from HCLK actually. S...

Why can I ping my STM32F417ZGT6 via cmd but can't open it's website via Chrome?

Hello all,As part of a sub-project, I need to be able to call a local web page using an STM32F417ZGT6. The code was generated and written with Cube IDE and tested on a MCB32 board with a STM32F107 processor. On the MCB32 board the web page can be cal...

HTTP request to my STM32 make it loose connection with Ping - No web pages are shown

Hi!I have done the following this:Make so ping works - OK (https://controllerstech.com/stm32-ethernet-1-connection/)Create a simple echo TCP Server - OK (https://controllerstech.com/stm32-ethernet-4-tcp-server/)These things works. Very good.But then ...

I want to add support of EAPOL(802.1x authentication) on stm32F4 controller using mbedTLS library and FreeRTOS. Request to provide supplicant/client source code if available with anyone. Using mbedTLS 3.2.1 stack and LwIP 2.1.3 stack in my project.

Sleep mode with FreeRTOS enabled

I want to be able to make the STM32G474 go to sleep when certain conditions are met.I've created a small project to test the feature. The `app-freertos.c` file is like this:#include "FreeRTOS.h" #include "task.h" #include "main.h" #include "cmsis_os....
