This document describes how to use the demonstration firmware for the DMX-512
communication protocol receiver. The USART (universal synchronous asynchronous
receiver transmitter) module of the STM32F103Zx (ARM 32-bit Cortex™-M3)
microcontroller unit receives the data from the DMX-512 controller via an RS-485
transceiver. This receiver is compatible with the latest DMX-512 protocol, and can also be
used with any DMX-512 controller having a “NULL” start code.
