DAQmxCreateCOPulseChanTicks
int32 DAQmxCreateCOPulseChanTicks (TaskHandle
taskHandle, const char counter[], const char
nameToAssignToChannel[], const char sourceTerminal[], int32
idleState, int32 initialDelay, int32 lowTicks, int32
highTicks);
Purpose
Creates channel(s) to generate
digital pulses defined by the number of timebase ticks that the
pulse is at a high state and the number of timebase ticks that the
pulse is at a low state and also adds the channel to the task you
specify with taskHandle. The pulses appear on the
default
output terminal of the counter unless you select a different
output terminal.
Parameters

|
| Name |
Type |
Description |
| taskHandle
|
TaskHandle |
The task to which to add the channels that this
function creates. |
| counter
|
const char []
|
The name of the counter to use to create virtual
channels. You can specify a list or
range of physical channels. |
| nameToAssignToChannel
|
const char []
|
The name(s) to assign to the created virtual
channel(s). If you do not specify a name, NI-DAQmx uses the
physical channel name as the virtual channel name. If you specify
your own names for nameToAssignToChannel, you must
use the names when you refer to these channels in other NI-DAQmx
functions.
If you create multiple virtual channels with one call to this
function, you can specify a list of names separated by commas. If
you provide fewer names than the number of virtual channels you
create, NI-DAQmx automatically
assigns names to the virtual channels. |
| sourceTerminal
|
const char [] |
The terminal to
which you connect an external timebase. You also can specify a
source terminal by using a terminal
name. |
| idleState
|
int32 |
The resting state of the output terminal.
| Value |
|
Description |
| DAQmx_Val_High
|
|
High state. |
| DAQmx_Val_Low
|
|
Low state. |
|
| initialDelay
|
int32 |
The number of timebase ticks to wait before generating the
first pulse. |
| lowTicks
|
int32 |
The number of timebase ticks that the pulse is low. |
| highTicks
|
int32 |
The number of timebase ticks that the pulse is high. |
Return Value
| Name |
Type |
Description |
| status
|
int32 |
The error code returned by the function in the
event of an error or warning. A value of 0 indicates success. A
positive value indicates a warning. A negative value indicates an
error. |
