Lumenera_GpioRead


Header: ThirdPartySdk.h
Namespace: avl

Reads GPI pins.

Syntax

void avl::Lumenera_GpioRead
(
	Lumenera_State& ioState,
	const atl::Optional<int>& inDeviceID,
	bool& outGpi0,
	bool& outGpi1,
	bool& outGpi2,
	bool& outGpi3
)

Parameters

Name Type Range Default Description
Input will be modified ioState Lumenera_State& Object used to maintain state of the function.
Input value inDeviceID const Optional<int>& 1 - 10000 NIL Device identifying number
Output value outGpi0 bool&
Output value outGpi1 bool&
Output value outGpi2 bool&
Output value outGpi3 bool&

Remarks

GPIO pin identification

Some cameras enumerate pins starting from 1, so outGpi0 might be GPI1 and inGpo0 might be GPO1. Similarly for other pins.

Camera driver software

This filter is intended to cooperate with cameras using their vendor's SDK. In order to connect with the camera, it is required to install Lumenera SDK software.

Lumenera SDK can be downloaded from the following website: https://www.lumenera.com/sdk.html

Recommended Lumenera SDK version for Aurora Vision Studio usage is 6.3.

Remember to install camera drivers from Lumenera SDK, in directory %LUMENERA_SDK%\Redist. The driver for USB is Redist LU, LM, LW, LC, LT, USB. The best is to use All Driver Install
Follow these instructions for quick install:

  • open cmd.exe
  • copy to opened window (enters driver directory):
    cd "%LUMENERA_SDK%\Redist\Redist LU, LM, LW, LC, LT, USB\All Driver Install"
  • copy to opened window (installs the driver):
    • For 64 bit Windows
      luihlp64.exe -inf -dll -ax
    • For 32 bit Windows
      luihlp.exe -inf -dll -ax
Camera identification

When there is only one Lumenera camera connected, the field inDeviceID can be set to Auto. In this situation, the first available camera will be used.

inDeviceID can be used to pick one of multiple cameras connected to the computer. inDeviceID should be set to camera ID.

Multithreaded environment

This function is not guaranteed to be thread-safe. When used in multithreaded environment, it has to be manually synchronized.
