I USED STM32H747 DEV BOARD, I GOT THIS ERROR WHEN I USED TO PROGRAMM ETHERNET, GIVE ANY SOLUTION

Connect with LwIP to port 5000

Hi Guys,I want to connect a server via port 5000.When connecting to other server with port 80 there is no problem, but when connecting with port 5000 it doesn't works.IP_ADDR4( &remote_ip, 11, 12, 13, 14);CommDropsTcpConn = netconn_new(NETCONN_TCP);n...

LwIP_HTTP_Server_Netconn_RTOS for Nucleo 767ZI isn't converted properly for STM32CubeIDE and it does not build.

CubeIDE version 1.6.0, Firmware version F7_1.16.0, on MacOSIn CubeIDE, start a new project from the examples, choose the nucleo-144 for 767ZI and LwIP. This leaves the LwIP_HTTP_Server_Netconn_RTOS example. But it will not build.There is a missing li...

Nucleo-L496ZQ-P problem with L4 examples : PWR_STOP1_RTC and PWR_STOP2_RTC

I cannot get PWR_STOP1_RTC nor PWR_STOP2_RTC to wake up as expected using interrupt mode (WFI).I've tried multiple examples of low power from the L4 examples:PWR_STANDBY, PWR_STANDBY_RTC, PWR_STOP1, PWR_STOP1_RTC, PWR_STOP2, PWR_STOP2_RTC.Standby mod...

Resolved! VBUS sensing doesn't work because internal pull-up is activated during USB init rather than when connected - STM32F072

Hi all, I just thought I'd add to the list of questions about USB! :grinning_face_with_sweat:I read AN4879 and it says "when the host presence is detected by the device, the device connects its pull up resistor". This is very clear - first detect the...

UART DMA receive via RTOS

hey therethere is a simple question: how can I receive data on my UART in DMA mode using RTOS? recently I ran a project where I just get all the data right when they arrived using UART DMA. but not I what the whole process to be done using RTOS. how ...

STM32H747i Lwip support

Hi,In the STM32H7Cube code, There is no LwIP example/Application code for STM32H747-eval. Can anyone direct me towards the same?Or let me know the delta between STM32H743 and STM32H747 LWip configuration.The most important code i need is the ethernet...

Exchange data between microcontroller / C# programm and flash with same connection

Hi,I have a question about STM32G4. I want to exchange data between microcontroller and a C# programm (by usb) on windows. But, sometimes I want to upgrade the program in the microcontroller with this same connection (usb)How I can do this ? I need t...

Is there a single usable HAL Documentation for L4 series?

Hello!I downloaded "Description of STM32L4 HAL and low-layer drivers UM1884" and am trying to learn how to program STM32 Microcontrollers, but the descriptions of the functions are lacking, to say the least. The document even refers to header files a...

STM32L1 FreeRTOS tickless idle with RTC wakeup

Posted on October 20, 2016 at 20:04 I'd like to implement vPortSuppressTicksAndSleep() to put the MCU into sleep or stop mode when there is nothing to do in FreeRTOS tasks. It should be woken up by an EXTI interrupt or RTC wakeup. In my implement...
