NIHSDIO_ATTR_DRIVE_TYPE
Specific Attribute
| Data type |
Access | Applies to | Coercion | High-Level Functions |
|---|---|---|---|---|
| ViInt32 | R/W | Channel | None | N/A |
Description
Specifies what the data channels generate when set to logic 1. Using the open collector setting to generate a Z is useful for wired logic buses, such as I2C or SMBus.
 |
Notes NI 656x devices only support the active drive setting.
NI-HSDIO returns an error if you try to configure the channels on these
devices for open collector generation. NI 654x devices support open collector generation only for static generation. NI-HSDIO returns an error if you try to configure the channels on these devices for open collector dynamic generation. |
This property is only valid for generation sessions.
Defined Values:
| Active drive (75) | The Generation Voltage High Level for the device is produced at the channel electronics when the Pattern Generation Engine generates a binary 1. |
| Open collector (76) | The channel electronics assume a high-impedance state when the Pattern Generation Engine generates a binary 1. |
