Protocol break relay for valid JSON on the W5500-EVB-Pico.
Uses the WIZnet W5500 on the W5500-EVB-Pico in MACRAW mode to pass raw packets to the RP2040. A protocol break is implemented by throwing away the protocol information of received packets, then the payload is validated as JSON, and finally a new UDP packet is constructed to forward the contents on.
You will need a debug probe that supports the Serial Wire Debug (SWD) protocol.
