Description
| Mode | Description |
|---|---|
| GPIO_MODE_STROBE | The GPIO acts as a strobe that reacts to the trigger input. |
GPIO_MODE_NORMAL | The GPIO can either be set or cleared. |
GPIO_MODE_PULSE | A series of pulses can be driven on the GPIO. |
GPIO_MODE_BUSY | The GPIO is set whenever the camera is unable to respond to a trigger. |
| GPIO_MODE_FLASH | The GPIO indicates the interval during which a flash or strobe light can be fired. This mode can be used for gated lighting. |
| GPIO_MODE_INPUT | The GPIO functions as a General Purpose Input. The status value of the GPI signal can be read and returned. |
| GPIO_MODE_ACTION_STROBE | Enables the GPIO Strobe action. When an action command is received, the camera will output one or more frames, according to the trigger settings. See: Action Type |
| GPIO_MODE_ACTION_NORMAL | Enables the GPIO Normal action. When an action command is received, the GPIO can either be set or cleared. See: Action Type |
| GPIO_MODE_ACTION_PULSE | Enables the GPIO Pulse action. When an action command is received, a series of pulses can be driven on the GPIO. See: Action Type |
See timing diagrams of the GPIO signals for different cameras by referring to the Camera Information section.
