ps2000_set_trigger2
int16_t ps2000_set_trigger2
(
int16_t handle,
int16_t source,
int16_t threshold,
int16_t direction,
float delay,
int16_t auto_trigger_ms
)
This function is used to enable or disable triggering and set its parameters. It has the
same behavior as ps2000_set_trigger, except that the delay parameter is a
floating-point value.
For oscilloscopes that support advanced triggering, see
ps2000SetAdvTriggerChannelConditions and related functions.
Applicability
Triggering is available in block mode and fast streaming mode only
Arguments
handle: the handle of the required oscilloscope
source: specifies where to look for a trigger. Use
PS2000_CHANNEL_A (0), PS2000_CHANNEL_B (1) or
PS2000_NONE (5).
threshold: the threshold for the trigger event. This is scaled in
16-bit ADC counts at the currently selected range.
direction: use PS2000_RISING (0) or PS2000_FALLING (1)
delay: specifies the delay, as a percentage of the requested
number of data points, between the trigger event and the start of
the block. It should be in the range -100% to +100%. Thus, 0%
means that the trigger event is at the first data value in the block,
and -50% means that it is in the middle of the block. If you wish to
specify the delay as an integer, use ps2000_set_trigger instead.
Note that if delay = 0 and you call ps2000_stop before a trigger
event occurs, the device will return no data.
auto_trigger_ms: the delay in milliseconds after which the
oscilloscope will collect samples if no trigger event occurs. If this is
set to zero the oscilloscope will wait for a trigger indefinitely.
Returns
0: if one of the parameters is out of range
non-zero: if successful
