Constructor & Destructor Documentation

◆ TriggerGenerator()

VIB_NET::TriggerGenerator::TriggerGenerator ( )

Default constructor for the device object

The device must be opened with Open() before it can be used.

Member Function Documentation

◆ ConfigureGet()

UInt32 VIB_NET::TriggerGenerator::ConfigureGet ( String ^ Command )

Generic function to read data from the FPGA trigger unit.

The command string is case insensitive. The syntax is described in the following table:

Name	Result
`Version`	Trigger unit firmware version number
`TrigIn`	Binary representation of the Trigger Input signals
`TrigIntern`	Binary representation of the internal trigger signals
`Counter<A...B>[,Reset]`	Current counter value with optional counter reset

Parameters

Command Command String^

Returns: RegisterValue Reference to result data

Example:: C#:
UInt32 TrigVersion=0;

UInt32 TrigInState=0;

//read the version(build date) of the trigger design

TrigVersion = pTriggerGenerator.ConfigureGet("Version");

//read the state of the TrigIn<0...X>:

TrigInState = pTriggerGenerator.ConfigureGet("TrigIn");

◆ ConfigureSet()

void VIB_NET::TriggerGenerator::ConfigureSet ( String ^ Command )

Generic function for controlling the FPGA trigger unit.

Each command string starts with the name of the parameter followed by a '=' character and the new value. The string is case insensitive.
Valid combinations of parameters and values are described in the following table:

Unit	Name	Value	Example
Multiplexers	`TrigOut<0...3>_Mux`	<Input signal>[`,invert`]	`"MuxIntern0=GenA,invert"`
	`MuxIntern<0...3>`
	`Gen<A...B>_Mux`
Signal Generator	`Gen<A...B>_tLow`	<Low time>[`ms\|ns\|us(default)`] (set to 0 for external trigger)	`"GenA_tLow=0"`
	`Gen<A...B>_tHigh`	<High time>[`ms\|ns\|us(default)`] (set to 0 for external trigger)	`"GenA_tHigh=50us"`
	`Gen<A...B>_tDelay`	<Delay time>[`ms\|ns\|us(default)`] (only used in triggered mode)	`"GenA_tDelay=2ms"`
Trigger Logic	`LUT<0...1>`	<LUT equation>	`"LUT0=TrigIn1&TrigIntern0"`
	`DividerA`	<Divider value>[,< InputEvent>] (default: TrigIn0_Rising)	`"DividerA=5,TrigIn2_Falling"`
	`DividerA_Reset`	`On\|Off\|TrigIntern2\|TrigIntern3`	`"DividerA_Reset=Off"`
	`Counter<A...B>`	<Max. Counter value>[,<InputEvent>] (default: ,TrigIn0_Rising)	`"CounterB=500,TrigIn0/1_Both"`
	`Counter<A...B>_ON`	<Counter ON value>	`"CounterB_ON=100"`
	`Counter<A...B>_OFF`	<Counter OFF value>	`"CounterB_OFF=200"`
	`Counter<A...B>_Start`	`Off\|On\|TrigIntern2\|TrigIntern3`	`"CounterB_Start=On"`
	`Counter<A...B>_Reset`	`Off\|Auto\|TrigIntern2\|TrigIntern3`	`"CounterB_Reset=Auto"`
Interrupt	`IntTrigger`	`TrigIn<0...3>[_Rising\|_Falling\|_Both\|_Off]` (default: `_Rising`) `TrigIntern<0...3>[_Rising\|_Falling\|_Both\|_Off]` (default: `_Rising`)	`"IntTrigger=TrigIn0_Falling"`

The command string can consist of multiple control commands, which are separated by spaces.
Each unit is controlled independently. For example changing TrigOut0 doesn't influence TrigOut1

Parameters

Command Command String^

Example:: C#:
//create a 1kHz signal

pTriggerGenerator.ConfigureSet("GenA_tLow=500us GenA_tHigh=500us");

//use it for output zero

pTriggerGenerator.ConfigureSet("TrigOut0_Mux=GenA");

//connect the generator to the camera trigger output 0

pCameraTrigger.Set(0,VIB_NET.CameraTrigger.eTRG_SOURCE.TRIGGEN_OUT0);

◆ Reset()

void VIB_NET::TriggerGenerator::Reset ( )

Resets the device to default settings.
