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.
