==DALI Master component==
A serial based communications protocol designed for controlling lighting, specifically digitally controlled dimmable fluorescent ballasts. DALI requires the signals to be level shifted from  VCC and GND to +9.5V - +25.5V and GND.  The master component can addess up to 64 individual slaves & up to 16 groups.

==Component Source Code==
A serial based communications protocol designed for controlling lighting, specifically digitally
controlled dimmable fluorescent ballasts. DALI requires the signals to be level shifted from
VCC and GND to +9.5V - +25.5V and GND.
The master component can addess up to 64 individual slaves & up to 16 groups.


==Examples==
Please click here to download the component source project: [https://www.flowcode.co.uk/wiki/componentsource/FC_Comp_Source_DALI_Master.fcfx FC_Comp_Source_DALI_Master.fcfx]
DALI Master Example, reads the value of a keypad and sends out DALI commands based on the key pressed, 1 = switch on a slave's light, 2 = switch off a slave's light, 3 = read the slave's light level.
