tsplink.TRIG_SYNCHRONOUSM 6
Detects rising-edge triggers as an input. Asserts a TTL-low
pulse for output.
tsplink.TRIG_RISINGA 7
Detects rising-edge triggers as input. Asserts a TTL-low pulse
for output.
tsplink.TRIG_RISINGM 8
Edge detection as an input is not available. Generates a
TTL-high pulse as an output trigger.
When programmed to any other mode, the output state of the I/O line is controlled by the trigger logic, and the
user-specified output state of the line is ignored.
When the trigger mode is set to
tsplink.TRIG_RISING
, the user-specified output state of the line will be
examined. If the output state selected when the mode is changed is high, the actual mode used will be
tsplink.
TRIG_RISINGA
. If the output state selected when the mode is changed is low, the actual mode used will
be
tsplink.TRIG_RISINGM
.
The custom variable mode stores the trigger mode as a numeric value when the attribute is read.
To control the line state, use the
tsplink.TRIG_BYPASS
mode with the
tsplink.writebit()
and the
tsplink.writeport()
commands.
Example
tsplink.trigger[3].mode =
tsplink.TRIG_RISINGM
Sets the trigger mode for the
synchronization Line 3 to
tsplink.TRIG_RISINGM
.
