Activate an IO mode by
v4l2-ctl -c io_mode=<IO mode number>
The IO mode remains set until it is deactivated with
v4l2-ctl -c io_mode=0
Following you will find timing diagrams to illustrate the specific behavior of each mode.
In all modes you can activate a trigger mode as described in Trigger Modes.
In this mode the flash signal is deactivated and the trigger signal is active high.
In this mode the flash signal is active high and the trigger signal is active high.
In this mode the flash signal is active low and the trigger signal is active high.
In this mode the flash signal is deactivated and the trigger signal is active low.
In this mode the flash signal is active high and the trigger signal is active low.
In this mode the flash signal is active low and the trigger signal is active low.
In the table below you can find, which camera supports which flash signal in IO Mode (1)
