DMX-512 Master component

A serial based communications protocol designed for controlling theatrical equipment such as dimmers, fog machines and intelligent lights. DMX-512 Slave devices are daisy chained together with a final 180R terminating resistor at the end of the chail. DMX requires the signal to be level shifted from VCC and GND to +2.5V and -2.5V.

Macro reference

Initialise

Fc9-comp-macro.png Initialise
Configures the UART serial interface. 
Fc9-void-icon.png - VOID Return


SendDataChain

Fc9-comp-macro.png SendDataChain
Transmits the BREAK, MAB and StartCode followed by the contents of the data channels. 
Fc9-u8-icon.png - BYTE StartCode
 
Fc9-void-icon.png - VOID Return


SetDataChannel

Fc9-comp-macro.png SetDataChannel
Sets the data byte in a data channel 
Fc9-u16-icon.png - UINT Channel
 
Fc9-u8-icon.png - BYTE DataValue
 
Fc9-void-icon.png - VOID Return


Property reference

Fc9-prop-icon.png Properties
Fc9-conn-icon.png Serial Properties
Fc9-type-16-icon.png Channel
UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller. 
Fc9-type-16-icon.png Baud Options
Baud rate option selector 
Fc9-type-14-icon.png Baud Rate
 
Fc9-type-5-icon.png TX
Pin to be used for Transmit data 
Fc9-conn-icon.png DMX Properties
Fc9-type-21-icon.png Data Channels
Number of data bytes used by the DMX chain, Max 512 bytes per transmission. 24 Bytes minimum to match minimum 1204us timing requirements, not all channels need to be used. 
Fc9-conn-icon.png Simulation
Fc9-type-7-icon.png Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD. 
Fc9-type-7-icon.png Console Data
Selects if the console data is automatically generated or not 
Fc9-type-21-icon.png Console Columns
Number of characters that can be displayed on a single line of the console. 
Fc9-type-16-icon.png Data Source
Simulation data source used to allow the component to connect to various remote devices Nothing - Simulation data is ignored COM port - Routes the communication data to and from a physical or virtual COM port Injector - Routes the communication data via a data injector component on the Panel.
