==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.

DALI Slave Example, listens for DALI messages and checks that the group is correct before attempting to process the request and if required reply to the master.

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.
