The DMX Reference Design Kit includes a Z8051-based DMX512-A Receiver reference design built with Zilog’s Z51F0811 MCU and a DMX512-A controller using Zilog’s Z51F320 MCU.
This reference design implements a DMX512-A controller toward providing a basic understanding of the DMX512-A protocol, including its theory of operation, by using a common lighting application example. The receiver functions mainly as a light controller and, alternately, as a sound generator. As a lighting device, the receiver obtains data from the DMX controller that manages the display of four high-bright LEDs using the Z51F0811 MCU’s PWM function. The brightness of these LEDs depends on the DMX512-A data that the Receiver obtains.
As a sound generator, the receiver activates a speaker that is connected to the Z51F0811 MCU’s buzzer driver. The UART peripheral of the Z51F0811 MCU is used to connect the DMX512-A receiver to the DMX512-A controller.
The key features of this reference design include:
-
Configurable DMX base slot address via six-position DIP switch
-
Optically-isolated DMX512-A interface
-
Four high-brightness LEDs
-
Buzzer for generating sound output
-
Ability to manipulate NULL start code (0) and alternate start code (207)
-
Three modes of operation: Local, PC, and Demo
-
Local Mode allows control via five on-board potentiometers (1 pot per DMX slot;
base address is hard coded in the firmware)
-
PC Mode allows control via a PC application
-
Demo mode allows pre-stored sequences to be generated
