Software Development Environment (DALI Protocol Stack)


Renesas is a member of the Digital Illumination Interface Alliance (DiiA). We have offered MCU products, evaluation boards, and protocol stacks supporting the DALI interface for over a decade, and a large number of customers in many countries have adopted these products. DALI protocol stack components from Renesas have been tested Official DALI tester *1, who must all be members of the DiiA, so customers can use them with confidence. A number of library versions have also been developed by partner vendors working closely with Renesas. Moving forward, Renesas is committed to fostering the widespread adoption of DALI by supporting the development work of customers in collaboration with our partner vendors.


Provides a convenient environment for trying out DALI-2 .

  • Tested Official DALI tester *1
  • Versions are available to match specific MCU products.
  • Substantially reduces the workload and time associated with development.
  • Application notes providing a basic understanding of DALI are available.
  • Evaluation version is provided by software automatic generation tool and application note.
