libartnet Migrate in lwip stack use in stm32f4

[Parth Sanepara]

Hello,

I am not sure libartnet is compatable with lwip stack but right now I am implement libartnet in lwip stack. all files compiles successfully but network.c file is most of related to linux/win networking socket apis. so I need help in those migration in lwip stack.

Thanks

You might like to just look at https://github.com/OpenLightingProject/rp2040-dmxsun which uses lwIP and supports Art-Net.

Although it doesn't look like it supports all of the Art-Net functionality...

Hello,

Yes, most probably the same as this. I am developing like Artnet Node. which can receive data from DMX-workshop to my device connected to dmx application. 

device based on stm32f4 +RTOS + Lwip (Ethernet TCP/IP stack). if you have any suggestions for that it might be helpful.

I tested with the rp2040-dmxsun Artnet file in my project. I am importing in stm32 Project top of lwip stack. I got the Artnet poll and Arnetpoll-reply. device found in DMX-Workshop. but I'm not able to properly get dmxout data. I tested with DMX-Workshop. when I connect and test with software. in software preset Chanel value update only once in a device after I change the value in of Chanel it's not reflected in a device.

if you have Artnet library with lwip or any other references code/Documents and suggestions please provide them, it could be most helpful for me. 

Thanks

Hi, chiming in a bit late on this one ;)

Indeed, rp2040-dmxsun implements ArtNet but it's a custom
implementation, not really to be used as a library.

Are you using NO_SYS=1 for lwIP (meant for microcontrollers without an
OS, so you don't rely on any Linux/Unix socket behaviors) or do you have
the NO_SYS=0 where it is assumed that you have an OS that takes care of
many parts?

In the NO_SYS=1-case, make sure you regularly call the lwIP-functions it
needs to to it's job.
