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
| Input | |||||||||||
| Name | Type | Description | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| taskHandle | TaskHandle | The task to which to add the channels that this function creates. | |||||||||
| counter |
|
The name of the counter to use to create virtual channels. You can specify a list or range of physical channels. | |||||||||
| nameToAssignToChannel |
|
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.
|
|||||||||
| 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. |
