Gate generator (GATEGEN)

LogicPool (TEMPLATE)

This module will created a Pulse after the arrival of a trigger. The pulse width and delay can be set. After the pulse was created , the module can trigger it self again. This feature can be used to create CLOCKs. It Does not need any Hardware submodule to work.

Models

There is three model, the only diferent is the width of an internal counter.

Model 0 -> 32 Bits Model 1 -> 24 Bits Model 2 -> 16 Bits

Module Address: 'G' or Ox47

Read register

Read registers

Register Address	Name	Data
0	VERSION, MODEL and Driver if any	Bit 31..25: VERSION HI Bit 24..16: VERSION LOW Bit 15..8 : MODEL Bit 7: Status Bit 6..0: Driver
1	STATUS	Bit 7..0 is the counter active? is running?
2	COUNTER_VALUE	Bit 31..0 Counter value, the width depends on Model

Write register

Write registers

Register Address	Name	Data
0	TRIGGER	Bit 7..0: Select the input driver of the trigger
1	ENABLE	Bit 7..0: Select the input driver of the enable signal of the counter
2	DELAY	Bit 31..0: Set the value of the delay after the trigger, after writing this register the counter will be reseted
3	DURATION	Bit 31..0: Set the width of the pulse, after writing this register the counter will be reseted
4	RETRIGGER	Bit 0: If set after the Pulse was created the counter will be reseted and the module will be triggered again. After writing this register the counter will be reseted

LabVIEW Vi

GATEGEN.vi

Pulse generator (GateGenerator) with programable Delay and Duration. Can be also used as Clock, Event or Time Counter.

The meaning of almost inputs and outputs of this Vi depends on the input "Function". The global inputs and outputs does not depend on the "function" input:

Glogal Inputs

DIO_HV#: number of HV digital output to be accesed (1..255).

USB In: Handle to the LogicBox (create by open.vi), if not connected will take a global. parameter, this only works with one LogicBox at a time.

error in: error handling input

Global Outputs

USB out: Handle to the LogicBox.

error out: error handling output

Functions

 Connect: enable, configurate and set input/value of the HV digital output.
          Inputs:
          "DO"  : set the signal number which will drive the output, this signal can be set or clear
                  manually using the module "B_S.vi" (Bool to Signal).
          "DI"  : get the signal number of which drives this input. 
       

 Get Status: the cicuitry of the digital output can detect two errors, under voltage or logic state
             undifined. Only the first 8 channels support this features
             Input: "Channel": number of channel to be configured 
             Output: Output Status

 Set DO: set the signal number which will drive the output, this signal can be set or clear manually
         using the module "B_S.vi" (Bool to Signal). 
         Input: "Channel": number of channel to be configured
                "DO" set the signal number which will set the output value.
