Communication to 6 modules with microcontroller


We are Using 6 modules in a chassis. Each has its own Microcontroller/microprocessor STM32.

We want to communicate to one of these 6 modules at random from the outside world via Ethernet and a back plane board. The module connect to the backplate via a power and signal connector. We do not want to use the Master/Slave concept and use another processor on the back plane.

The schematic design should work for industrial applications from -40 to 100 C.


Only people with experience with real-time embedded programming.

Beceriler: C Programlama, Mikrodenetleyici, Gömülü Yazılım

Hi there.. My thinking is that you let the 6 work in an alternate fashion, one microcontroller at a time.. Thia way you won't miss any incoming message. This may also save you some energy as the other five will be idl Daha Fazla
