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.
DALI Slave Example1
Downloadable macro reference
ReceiveForwardFrame
Attempts to receive an 16-bit command from the master controller.
0xFFFF indicates timeout or no reply
Parameters
- This macro has no parameters
Return value
CheckForIndividualAddress
Tests the 16-bit incoming data for the defined individual address
Returns 0 for no match, returns 1 for a match
Parameters
- UINT Data
Return value
CollectDataByte
Returns the data byte from a 16-bit data packet
Parameters
