This reference design demonstrates the implementation of a DALI Master using ATxmega32E5 microcontroller. The DALI master can control DALI slaves used in lighting network control applications in building automation and smart home. The design can connect to a host system using a RS232 or an USB interface.
Manchester Encoding and decoding with USART and XCL modules
EDMA (Enhanced Direct Memory Access) used for data transmission
USB and RS232 communication interface to host system
