Kind

Description

The device trigger kind determines how the device trigger responds to the device trigger input signal.

Use DevTrInGetKinds() to find out which trigger kinds are supported by the device trigger input. Read more on device trigger kind.

Default value: TK_RISINGEDGE if supported, else TK_FALLINGEDGE.

Function Documentation

uint64_t DevTrInGetKinds	(	LibTiePieHandle_t	hDevice,
		uint16_t	wInput
	)

Get the supported trigger kinds for a specified device trigger input.

Parameters

[in]	hDevice	A device handle identifying the device.
[in]	wInput	The trigger input index identifying the trigger input, 0 to DevTrInGetCount() - 1.

Returns

Supported trigger input kinds, a set of OR-ed TK_* values.

Status values

INVALID_INPUT	The requested trigger input is invalid.
NOT_AVAILABLE	With the current settings, the trigger input is not available.
NOT_SUPPORTED	The device has no trigger inputs.
INVALID_HANDLE	The handle to the device is invalid.
OBJECT_GONE	The object indicated by the handle is no longer available.
LIBRARY_NOT_INITIALIZED	The library is not initialized, see LibInit().
SUCCESS	The function executed successfully.
