SetIOMask

Syntax

LONG SetIOMask (LONG nIOMask)

Description

Using SetIOMask(), you can define each GPIO as an input or output. The SetIO() function sets the additional digital outputs (GPIOs) of the uEye.

Hinweis

The GPIOs are available with the GigE uEye HE and USB uEye ME/LE (board level only) cameras. The GPIOs are not provided with optocouplers and use TTL voltages. For information on GPIO wiring, please refer to the "Electrical specifications" chapter in the uEye Manual.

Hinweis

To use hardware triggering with the uEye cameras, we suggest that you use the trigger input provided for this purpose (see SetExternalTrigger()).

To connect and control a flash (strobe) unit for the uEye cameras, it is recommended to use the flash output provided (see SetFlashStrobe()).

Parameters

nMask	Bit mask for inputs/outputs.
0x00 (00)	Use both GPIOs as inputs.
0x01 (01)	Use the first GPIO as output, the second one as input.
0x02 (10)	Use the first GPIO as input, the second one as output.
0x03 (11)	Use both GPIOs as outputs.
IS_GET_INPUT_MASK	Returns the IOs to be used as inputs.
IS_GET_OUTPUT_MASK	Returns the IOs to be used as outputs.

Return values

IS_SUCCESS	Function executed successfully
IS_NO_SUCCESS	General error message
When used with IS_GET_INPUT_MASK IS_GET_OUTPUT_MASK.	Bit masks of the IOs to be used.
