DALI Slave 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 using external circuitry.
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
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.
