DMX-512 Slave 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.

GetDataChannel
|
GetDataChannel |
| Gets the data byte from a data channel | |
 - UINT
|
Channel |
 - BYTE
|
Return |
Initialise
|
|
Initialise |
| Configures the UART serial interface. | |
 - VOID
|
Return |
ReceiveDataChain
|
|
ReceiveDataChain |
| Waits for a BREAK, MAB and StartCode followed by the contents of the data channels. Returns 0 to indicate a timeout and 1 to indicate succesful reception. | |
| - BYTE
|
Timeout |
| 0 = Don't wait, 1 - 254 = 1ms - 254ms, 255 = Wait forever | |
| - BYTE
|
Return |
Property reference
|
Properties |
|
Serial Properties |
|
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. | |
|
RX |
| Pin to be used for Receive data | |
|
|
Baud Options |
| Baud rate option selector | |
|
Baud Rate |
|
|
DMX Properties |
|
Data Channels |
| Number of data bytes to receive from the master, Max 512 bytes per transmission. 24 Bytes minimum from Master to match minimum 1204us timing requirements, not all channels need to be used. | |
|
|
Start Channel |
| Channel from the master which we want to start taking our data channels | |
|
Use Start Code |
| Do we wait for the start code or simply begin receiving data? | |
|
|
Start Code |
| Start code value to listen out for, range 0-255 | |
|
|
Simulation |
|
|
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. | |
|
|
Console Data |
| Selects if the console data is automatically generated or not | |
|
|
Console Columns |
| Number of characters that can be displayed on a single line of the console. | |
|
|
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. | |
