Point Grey Flea3 USB 3.0 Technical Reference 6 Image Acquisition
Field Bit Description
ON_OFF [6]
Read: read a status
Write: ON or OFF for this feature
0: OFF, 1: ON
If this bit = 0, other fields will be read only
[7-19] Reserved
Value [20-31] Value.
6.4.10.3 PIO_DIRECTION: 11F8h
If the IOx_Mode bit is asserted (write a ‘1’), this means the GPIO pin is currently configured as an output and the Pin_
Mode of the GPIO pin (see the GPIO_CTRL_PIN_x register) is GPIO_Mode_ 8. Otherwise, the Pin_Mode will be GPIO_
Mode_0 (Input). The PIO_DIRECTION register is writeable only when the current GPIO_Mode is GPIO_Mode_ 0 or
GPIO_Mode_8.
Field Bit Description
IO0_Mode [0]
Current mode of GPIO Pin 0
0: Other, 1: Output
IO1_Mode [1]
Current mode of GPIO Pin 1
0: Other, 1: Output
IO2_Mode [2]
Current mode of GPIO Pin 2
0: Other, 1: Output
IO3_Mode [3]
Current mode of GPIO Pin 3
0: Other, 1: Output
[4-31] Reserved
Format
6.4.10.4 SOFTWARE_TRIGGER: 62Ch
Bit 0 of this register indicates if the camera is ready to be triggered again for
both software and hardware triggering.
Field Bit Description
Software_Trigger [0]
This bit automatically resets to zero in all trigger modes except Trigger Mode 3.
Read: 0: Ready, 1: Busy
Write: 0: Reset software trigger, 1: Set software trigger
Format:
6.4.10.5 ISO_CHANNEL/ISO_SPEED: 60Ch
Allows the user to query the camera’s isochronous transmission channel and speed information.
