Controlling image capture
Trigger delay advanced register
In addition, the cameras have an advanced register which allows even more pre-
cise delay of image capture after receiving a hardware trigger.
The advanced register allows the start of the integration to be delayed by max.
2
21
μs, which is max. 2.1 s after a trigger edge was detected.
Register Name Field Bit Description
0xF0F00834 TRIGGER_DELAY Presence_Inq [0] Presence of this feature:
0: N/A
1: Available
Abs_Control [1] Absolute value control
O: Control with value in the Value field
1: Control with value in the Absolute
value CSR
If this bit = 1, the value in the Value field
has to be ignored
--- [2..5] Reserved
ON_OFF [6] Write ON or OFF this feature, ON=1
Read: Status of the feature
OFF=0
--- [7..19] Reserved
Value [20..31] Value
If you write the value in OFF mode, this
field will be ignored.
If ReadOut capability is not available,
then the read value will have no meaning.
