niHSDIO_ReadStaticU32
Specific Function
C Function Prototype
ViStatus niHSDIO_ReadStaticU32 (ViSession vi, ViUInt32* readData);
Purpose
This function immediately reads the digital value on channels configured for static acquisition. Configure a channel for static acquisition using the niHSDIO_AssignStaticChannels function. Channels not configured for static acquisition return a zero.
Values obtained from static read operations are affected by data interpretation.
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession | This handle identifies your instrument session. vi was obtained from niHSDIO_InitAcquisitionSession. |
| readData | ViUInt32 | Bit-value of data read from channels configured for static acquisition. The least significant bit of readData corresponds to the lowest physical channel number (for example, readData of 0x00F0 means channels 4-7 are logic one, while the remaining channels are logic zero or are not configured for static acquisition). |
