LED lighting control using DMX512 control based on STM32F102C6T6 and STCS1APHR

STEVAL-ILL030V1

Overview

The purpose of the STEVAL-ILL030V1 demonstration board is to demonstrate the performance of ST devices in an LED lighting control application, using the DMX512 communication protocol demonstration firmware in transmitter, receiver and standalone modes.

The USART (universal synchronous asynchronous receiver transmitter) module of the STM32F103C6 ARM 32-bit Cortex™-M3 microcontroller is used to transmit/receive data via an RS-485 transceiver. The transmitter sends DMX512 packets with a NULL START code, according to the DMX512 2008 standard.

Main features

Jumper settings to configure the board in transmitter, receiver or standalone mode
The STCS1A device provides dimming control of the on-board LEDs
Over/undervoltage protection using the STBP120 voltage protection device
Uses the ESDAULC6-3BP6 ESD protection device for advanced USB protection
Option of powering the LEDs through an external power supply, or through a 5 V power supply output from the STBP120
Board uses an internal clock source, without a crystal
Mini-B type USB connector can be used if power for LEDs is supplied separately from external source
RoHS compliant
