Azure RTOS connection to Azure IoT hub

Hello,I have some, maybe senseless, questions about X-CUBE-AZRTOS and it's applications. I have downloaded and checked this firmware, and also examples.Here my questions:1 - Since Low-level driver interface handles connection between NeX Duo Core and...

How can I use the STm32L4 USB stack on a STM32U575 Board. Need to communicate over USB without using RTOS

Ethernet Rx interrupt issue on STM32F7

Hello guys, so I'm trying to establish an Ethernet communication between my PC and STM32F746G-DISCO without using LWIP. I set the Rx mode to interrupt and configured the MPU now the problem is the interrupt only works for 4 times. After looking I fou...

Ethernet for ST32F407 gave me HAL_ETH_ERROR_DMA when I plugin the ethernet cable

I have an STM32F407 with the ethernet PHY DP83848. I cannot ping the device if I'm using the LwIP because I'm facing some errors.I belive that this can be an bug in STM32CubeIDE 1.9.0.I do the following steps to reproduce the error.I start up my PCB ...

How do I determine when Virtual Com Port is closed/opened in my STM32L476 firmware?

I'm working with the Nucleo-64 development board with an STM32L476 microcontroller and I'm using the USB source code that STM32CubeMX has generated for me. I want to be able to find out when the Virtual Com Port is closed/opened on the PC that the Nu...

HAL_Delay stuck in a loop when using DFSDM and FATfs

I'm using a stm32L4R9 disco.I want to record PCM data from a mems microphone and store it on a sd card.I have managed to make a project that gets data using DFSDM.I have managed to make another project that simply create a .txt file on a sd card, usi...

On STM32H7, does the DMA that comes with USB-HOST support accessing non-32bit aligned memory addresses?

If a non-32bit aligned address is passed to the DMA to receive data (such as 0x24000002), the received data will be placed at the aligned address (0x24000000), but I don't see this limit in the chip manual , are there extra steps to make DMA support ...

Call HAL lib inside Call back

Hello, Is it Ok to read GPIO pins inside a timer call back as follow:void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef* htim){ if (htim == &htim2 ) //15 ms { BT1 = HAL_GPIO_ReadPin(GPIOx, Pin_x); BT2 = HAL_GPIO_ReadPin(GP...

Hi to everyone. Where can we find the manual of the STM32CubeL4 where it explain how to set up the functionalities of the uC? (For example TIMx -> PWM generation -> with HAL and Cube generator)

I found the manual of the HAL drivers and uC datasheet, but unfortunately I can not find how to setup some configuration on "Device Configuration Tool" such as PWM generation modes and how the peripheral works. Could someone help me?Where can I find ...
