Fast streaming mode only
PicoScope 2202, 2203, 2204, 2204A, 2205 and 2205A only
Not compatible with ETS triggering - has no effect in ETS mode
overviewBuffers: a pointer to a location where
ps2000_get_streaming_last_values will store a pointer to its
overview buffers that contain the sampled data. The driver creates
the overview buffers when you call ps2000_run_streaming_ns to
start fast streaming. overviewBuffers is a two dimensional array
containing an array of length nValues for each channel
(overviewBuffers[4][nValues]). Disabled channels return a
null pointer resulting in four overview pointers whether all channels
are enabled or not.
overviewBuffer [0]
overviewBuffer [1]
overviewBuffer [2]
overviewBuffer [3]
ch_a_max
ch_a_min
ch_b_max
ch_b_min
overflow: a bit field that indicates whether there has been a
voltage overflow and, if so, on which channel. The bit assignments
are as follows:
Bit 0 - Ch A overflow
Bit 1 - Ch B overflow
triggeredAt: an index into the overview buffers, indicating the
sample at the trigger event. Valid only when triggered is TRUE.
triggered: a Boolean indicating whether a trigger event has
occurred and triggeredAt is valid. Any non-zero value signifies
TRUE.
auto_stop: a Boolean indicating whether streaming data capture
has automatically stopped. Any non-zero value signifies TRUE.
nValues: the number of values in each overview buffer
