Extra Functions

Introduction

This documentation is about extra functions, that are not necessary to get it running, but can be used if need be.

Non-deprecated functions

ETH_setup_MAC_address_filtering

This function is used for perfect mac address filtering. It is used by giving it MAC-addresses as arguments. If you receive packets with those addresses, they will also be processed.

Deprecated Functions

There are deprecated functions for raw sending (ETH_raw_send) and custom protocol receiving (ETH_custom_protocol_receiver). Those can be used if you don't want to use UDP, but I don't know if they still work.

Raw receiving

If you want to receive messages, you need to have #define LWIP_HOOK_UNKNOWN_ETH_PROTOCOL(pbuf, netif) eth_reader(netif, pbuf) in the cubemx_main.h file.
