Syntax

INT is_SetIO (HIDS hCam, INT nIO)

Description

Achtung

This function is obsolete and should not be used anymore. We recommend to use the is_IO() function instead (see also Obsolete functions).

is_SetIO() sets the additional digital outputs (GPIOs) of the uEye or returns their current states. Using is_SetIOMask(), you can define each GPIO as a digital input or output.

Achtung

To be able to set the Status of a GPIO you must first configure the GPIO as output using is_SetIOMask().

If only one GPIO is configured as output the command is_SetIO() has no effect on the other GPIO.

Achtung

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.

Hinweis

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

Input parameters

hCam	Camera handle
nIO	Bit mask for outputs
0x00 (00)	Sets both outputs to 0.
0x01 (01)	Sets the first output to 1, the second one to 0.
0x02 (10)	Sets the first output to 0, the second one to 1.
0x03 (11)	Sets both outputs to 1.
IS_GET_IO	Reads the states of the GPIOs. If a GPIO is configured as input this reads the signal applied to the GPIO.

Return values

IS_SUCCESS	Function executed successfully
IS_NO_SUCCESS	General error message
When used with IS_GET_IO	Current setting
