OM13026 DALI reference board contains an example implementation of an isolated physical layer for the Digital Addressable Lighting Interface (DALI) bus with ARM 32bit Cortex M0 LPC111x microcontroller for the DALI protocol handling, and many I/O functions to steer external lighting drivers for solid state or compact fluorescent lighting applications. Up to four PWM signals are available to independently drive different lighting units. Frequency and resolution of the signals is software programmable.
ON/OFF signal can be used independently from PWM signals to switch lighting driver into OFF/ON state
I2C bus pins can be used to externally connect other devices like EEPROM or a temperature sensor
Analog A/D input is available via pin 8
IO signal is left open for the end user
Reduced system complexity with high performance MCU
High efficiency power conversion
Cost optimized
Low power consumption from the MCU (for bus power devices)
