Atmel has produced a reference design based on its SAM D20/21 series of microcontrollers for a standard-compliant Digital Addressable Lighting Interface (DALI) master.

The reference design implements the DALI control and communications protocol specified in IEC 62386-101, -102 and -207, and is compliant with the standard. The firmware supplied by Atmel includes application software, service software and drivers. Manchester encoding is implemented in software.

The reference design is intended to be used in conjunction with Atmel® Studio 7, the integrated development platform for developing and debugging Atmel SMART and AVR® MCU applications. It provides a seamless and easy easy-to-use environment for writing, building and debugging applications written in C/C++ or in assembly code. It connects to Atmel debuggers and development kits.

In addition, Studio 7 includes Atmel Gallery, an online app store which offers plug-ins developed by Atmel and by third-party tool and embedded software vendors.

Users can evaluate the DALI master reference design on a ready-made evaluation kit for the SAM D21, an MCU which uses the low-power ARM® Cortex®-M0+processor core. The Atmel SAM D21 Xplained Pro evaluation kit is ideal for evaluating and prototyping with the Atmel SAM D21, and its features can be supplemented with extension boards which are available for purchase individually. The reference design may easily be ported from the SAM D21 to other Atmel devices using the Atmel Software Framework.
