General Purpose I/O Interface

The General Purpose I/O (GPIO) interface gives access to the status of all I/Os available in the frame grabber. It also allows the user to control the ‘User Output Register’.

For more information on the General Purpose I/O and the User Output Register, please refer to the Functional Guide and the Hardware Manual sections .

Interface signals

Signal Width Direction Description
user_output_ctrl 16 Output

Control the User Output Register:

□ Ctrl[1:0] => UserOutput0
□ Ctrl[3:2] => UserOutput1
