Communication between STM32 and Raspberry Pi Ethernet

[polram]

Hello

I am working in a project where I'm connecting 2 boards STM32 with FDCAN Bus, one board has all the sensors connected, and the other one receives the data, basically I send floats (measures of the sensors) and It is done!, but now, I would like to transmit from my second STM32 (receiver) to a Raspberry Pi 3 via Ethernet. Honestly, I don't know where to start or what configuratios should I try

Thanks

Hello @polram, and welcome to ST Community!

For your case, I recommend starting by downloading one of ST’s LwIP examples, specifically the UDP echo client. You can then adapt it to your use case by creating a UDP protocol control block (PCB), copying your payload to it, and sending it on a port of your choice. On the Raspberry Pi side, you can create a UDP server script that listens on that port, receives the datagrams, and extracts the sent data.

Best regards,
