Development platform for digital-lighting design

The STLUX development environment, consisting of demonstration boards, a graphical configurator, software libraries, and compiler, provides everything needed to start designing high-performance LED lighting with STLUX385A, the first in a new family of lighting controllers featuring a breakthrough digital control technique from STMicroelectronics.

ST will unveil the STLUX development environment at PCIM Europe 2014 in Nuremberg with a plug-and-play demonstration board featuring all STLUX385A functionalities and a user-friendly ecosystem for programming PWM waveforms using the six on-chip SMED (State Machines Event Driven) digital controllers. The SMED is an advanced hardware-configurable state machine where state advancement is automatically triggered by internal or external events thereby ensuring faster response than a conventional interrupt-driven microprocessor. In addition, the STLUX385A supports smart-grid connectivity and DALI1 communication for remote control, enabling use in energy-efficient lighting throughout smart cities.

Using the STLUX development environment, designers can control the STLUX385A via a serial line and a console. The graphical SMED configurator simplifies design of innovative topologies targeting maximum efficiency at full load with minimum energy consumption in idle conditions, high-quality dimming with high current-control precision. Ready-to-use application examples are also provided.

The demonstration boards are currently available for sampling from ST. For further information and links to all components of STLUX ecosystem, please visit www.st.com/stlux_development_kit

The STLUX385A includes six SMEDs with 10ns reaction time, four analog comparators with internally-generated and external references, an Analog-to-Digital Converter (ADC) with an 8-channel sequencer, native DALI, built-in memory including 32Kbytes program Flash, serial and I²C communication channels, and an integrated low-power STM8® microcontroller. The STLUX development environment also provides a highly optimized compiler for the microcontroller, together with the related in-circuit debugger/programmer.
