How a Bare-Metal STM32 Art-Net Gateway Uses the WIZnet W5500 Hardware UDP Socket for Low-Latency DMX512 Output Overview Stage and performance lighting needs a gateway that converts the Art-Net commands a console sends over Ethernet into the DMX512 signal that fixtures receive directly. This project is an Art-Net → DMX512 gateway built on an STM32F411 (Black Pill) microcontroller. Its defining trait is bare-metal optimization. Instead of relying on an off-the-shelf network library, it controls the chip at the register level with a hand-written W5500 driver. Here the WIZnet W5500 is the…
