| summary | A DIY USB to DMX converter can be built using a UART chip (like FT232 or CH340G) and a MAX485. The converter works by periodically switching between receiving ASCII DMX frames via USB and transmitting DMX frames via the UART. It uses a 250ms cycle: disabling receive interrupts, setting the UART for DMX output (250 kbaud, 8 data bits, 2 stop bits), transmitting a DMX frame, then configuring the UART for serial input (57600 baud) and re-enabling receive interrupts. The received DMX data updates the outgoing DMX frame, ensuring only DMX data is transmitted via the UART. |
