DALI click  (MIKROE-1297)

DALI Click™ is a compact board that provides Digital Addressable Lighting Interface (DALI) to your design. Board features two optocouplers, push button and screw terminals. DALI Click™ communicates with target board via four mikroBUS™ lines (RST, CS, PWM and INT). Data between MCU and devices is transferred over two-wire differential bus by means of asynchronous, half-duplex, serial protocol. It is possible to address up to 64 devices in DALI stand alone systems and more than 64 devices as DALI subsystem (gateways). The board is designed to use 3.3V or 5V power supply. LED diode indicates the presence of power supply.
