Demonstration board for ST7 DALI (Digital Addressable Lighting Interface) with 1 master board, 2 slave boards, ST7DALI slave sof

The ST7DALI-EVAL provides a complete evaluation and demonstration platform for the on-chip lighting control features of the ST7DALI. ST7DALI devices integrate the DALI Communication Module (DCM) for serial communication with the controllable electronic ballasts, which provide the required starting voltage and operating current for fluorescent, mercury and other electric-discharge lamps. The DCM uses the DALI (Digital Addressable Lighting Interface) communications standard (IEC standard) based on the bi-phase Manchester asynchronous serial data format.

To help developers get started implementing the ST7DALI for control of lighting networks, the ST7DALI-EVAL provides a complete software/hardware application for networking up to 64 ST7DALI-based lighting control slave boards and testing the various DALI lighting control commands from an easy-to-use, PC-based software interface. When developers are ready to create their own applications, the kit serves as a reference design for a DALI gateway topology.

Key Features

  • Masterboard with preprogrammed ST72334x, power supply and serial port for host PC connection
  • Software CD-ROM for installation of the lighting control interface software
  • 2 Slave boards with preprogrammed ST7DALI microcontrollers implementing the DALI communication interface, 1 to 10V output (standard dimmable ballast input) and 12V power supply connector
