Any documentation for using LWIP + FreeRTOS + STM32H7?

[JJRR]

Hi,

I use STM32H7+LWIP+FreeRTOS. With using STM32IDE and this forum I can now ping to my board from PC and get answer - perfect.

Now I want to send and recieve some UDP packets - I can browse the code and try to understand how it all works (how to TX/RX). E.g. Is there any callback UDP_Packet_Recieved(..).. ?

But is there any documentation for this combo of LWIP + STM32 + FreeRTOS?

Or example how to send or recieve data?

Thank you.

Hello @Community member​,

I recommended you this article.

Also, Many STM32H7+LWIP+FreeRTOS examples are available in the STM32H7-LwIP-Examples package.

Thank you for your contribution.

Examples of UDP can be found in the Cube library, look in example projects for your board or similar board. For more info, please refer to the LwIP documentation.

(examples on https://github.com/stm32-hotspot do not contain UDP yet?)

There you can also find an echo utility to send echo requests to the board.

I use a simple python script instead :
