Timers 47
Timers
Your Matrox 4Sight GPm has 16 timers. These timers can each generate a timer
output signal which allows you to control the exposure time and other external
events related to the video source (such as a strobe). The timer signals can be
output to auxiliary output signals.
Each of the 32-bit timers (Timer 1 through 16) can count up to 1099511627775
clock ticks before resetting.
The timers can use one of the following as a clock source:
•
A clock that is internally generated.
Each timer can use your Matrox 4Sight GPm
unit‘s clock generator, which can generate a single clock with a programmable
period of 240 nsecs.
•
A clock from an external source.
In this case, you must define the appropriate
auxiliary input signal as a timer-clock input; the timer-clock input signal must
meet the electrical specification of the auxiliary signal.
•
A clock based on another timer output.
Timer 1 can use a clock based on Timer 2,
and Timer 2 can use a clock based on Timer 1.
•
A clock based on a rotary decoder’s output
. In this case, the timer will act more
as a counter because it is rare that a rotary decoder’s output is periodic.
To route a timer output on an auxiliary signal, use the MIL-Lite function
MsysControl()
with
M_IO_SOURCE
*
+ M_AUX_IOn
set to
M_TIMERm
. Set
up the timers using
MsysControl()
with
M_TIMER_...
