Ethernet and Wi-Fi¶

The network interface is where WebVisu, Modbus TCP and MQTT live. It is one interface with several services on it, which is why the project tree puts the wire first and the protocols under it.

Ethernet¶

To be written. Covers: the supported physical layers, addressing, and which boards have Ethernet at all — see the hardware reference.

Wi-Fi¶

To be written. Covers: joining the machine's network, and standing up an access point of its own so a phone can reach the panel where there is no network at all.

WebVisu¶

To be written. Covers: the same visualisation in a browser, served by the panel. Configuration is fetched once; after that only changed tags travel. A write from a browser is a command the panel may refuse, not a poke into memory.

Where the panel belongs¶

This part is decided. Encryption is not enabled on the reference chip — it does not fit in memory alongside control and graphics. The panel belongs on the machine's own isolated network, never on a public one.
