daliMaster

This is an Arduino™ library to control your DALI lamps with the brand new daliMaster shield, with built-in DALI bus power supply system. B:boom::boom:m!
Do you want to use this board with your Raspberry Pi also? Take a look here..double B:boom::boom:m!

Description

What is DALI?

DALI (Digital Addressable Lighting Interface) is a powerful protocol to control lighting. Through DALI you can dimmer your led lamps, ask them status, recall a predefined scenario and so on. If you want more information about DALI you can find many useful links to the bottom of this page.

Can I use DALI with my Arduino™?

Well, the answer is YES.

How?

With daliMaster shield! As the name suggests, that shield transforms your Arduino™ in a DALI master, acting as a bridge between I2C interface and DALI bus. Let's make an example to explain how it works.

Getting Started

  • Fit daliMaster shield on your Arduino™

  • Make connections (you can find an example here)

    • Connect your lamps to their ballasts
    • Connect your ballast to mains..be careful!
    • Connect your ballasts and daliMaster shield to DALI bus
    • Connect your 24V DC power supply to mains and to daliMaster..again, be careful!

  • If I'm right, now you should have all of lamps on. Let's turn them off.

  • Connect Arduino™ to your computer.

  • Download this library and load daliMaster/examples/serialControl.ino

  • Now open serial monitor, select 115000 as baudrate and you should see:

daliMaster start..
i2c master begin..
device(0x23) is ready!
  • Well, write and send this command:
-d -b 0
  • If everything went well your lamps now are off. But we don't like darkness, so let's switch them on to the minimum:
-d -b 1
  • Cool! Let's push them to maximum:
-d -b 254

Easy, isn't it? Now you can modulate all lamps from 0 up to 254 with those simple commands. 👍
