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.

Examples

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 Master Example1
