niHSDIO_ConfigureDataPosition
Specific Function
C Function Prototype
ViStatus niHSDIO_ConfigureDataPosition (ViSession vi, ViConstString channelList, ViInt32 position);
Purpose
Configures channels to be clocked in various ways by the Sample clock edges. You have three options for data position: rising edge, falling edge, or delayed.
Parameters
| Name | Type | Description | ||||||
|---|---|---|---|---|---|---|---|---|
| vi | ViSession | This handle identifies your instrument session. vi was obtained from the niHSDIO_InitAcquisitionSession or niHSDIO_InitGenerationSession function. | ||||||
| channelList | ViConstString | Identifies channels to apply settings. Use "" or VI_NULL to specify all channels. | ||||||
| position | ViInt32 | Specifies which edge of the Sample clock signal times the operation. You can also configure the device to generate data at a configurable delay past each rising edge of the Sample clock. Defined Values NIHSDIO_VAL_SAMPLE_CLOCK_RISING_EDGE (18)—The device samples or generates data on the rising edge of the Sample clock. NIHSDIO_VAL_SAMPLE_CLOCK_FALLING_EDGE (19)—The device samples or generates data on the falling edge of the Sample clock. NIHSDIO_VAL_DELAY_FROM_SAMPLE_CLOCK_RISING_EDGE (20)—The device samples or generates data with delay from rising edge of the Sample clock. Specify the delay using NIHSDIO_ATTR_DATA_POSITION_DELAY or the niHSDIO_ConfigureDataPositionDelay function.
