Corrupt data while reading using quadspi

Hi,I am working on stm32f779 eval kit.I am using quad spi.Following sequence works fine:Sequence 1:Erase any sector-> write value to particular sector -> read values from correct sector.Not working sequence ->Sequence 2:Erase a sector -> read values ...

I have a shiny new Samsung EVO 32GB formated as 29.8GB Fat32will it work ? I have a H743tried the FatFS applicationit doesn't find the card.FATFS_LinkDriver fails

How to run Ethernet on stm32f429 discovery board with DP83848 as PHY without FreeRTOS?

Hello everyone. Does have anyone a sample project about how to run Ethernet on stm32f429 discovery board with DP83848 as PHY without FreeRTOS? Including CubeMX project and IAR, KEIL, or CubeIDE as toolchain.Thanks in advance.

Unable to Transmit the Data (USB CDC ) to PC (STM32L476RG Eval Board)

Hi,I am trying to transmit the data(USB CDC) over PC but I didn't see any message printing on Serial Putty Console. Do I need to change any configuration settings. May I know , why transmission was not happening.. I am trying to dig into deep. so cou...

how to use CAN with CubeMX and STM32F1 / F4, UM1850 and other HAL+LL drivers documentation not up to date with new CAN Library since fall 2017

Hi everyone,I want to use CAN with my STM32F103CB and STM32F429ZIT, but the CAN TX and RX Pins do not do anything on both boards. I am using CubeMX 5.3 and F1 Lib 1.8.0 / F4 Lib 1.24.1From the CubeMX CAN example project for the STM32446E_Eval board I...

Is it possible to run into a race condition when calling HAL_GetTick()?

I am designing an application with a control loop of 1 ms, and I would like to use HAL_GetTick() as the way of clocking this loop. This is a safety critical system, and I would like to know if one will run into a race condition by calling this functi...

what is the difference between socket API and netconn api and what is thier function thanks

Is there a way to connect two STM32 through Ethernet (using a hub or multiplexer?)

Hello, I'm doing a project where two microcontrollers (maybe one STM32H7 and STM32F7) must be connected between them. These two microcontrollers should be connected to an external Ethernet port. Is there some type of hub or multiplexer that allows t...

Wouldn't it be much safer to initialize FreeRTOS before enabling interrupts?

Using FreeRTOS on a STM32L476RG we get unreliable boot behaviour because CubeMX generates:... /* Initialize interrupts */ MX_NVIC_Init(); /* USER CODE BEGIN 2 */ /* USER CODE END 2 */ /* Call init function for freertos objects (in freertos.c) */ MX_F...
