Using the Pololu SLO-scope Application
This application connects to the programmer, streams data from the SLO-scope, and provides the basic functionality
of a 10 or 20 kHz oscilloscope.
Pololu SLO-scope client for Windows.
Controls are available for setting the SLO-scope operating mode, adjusting the horizontal and vertical scales, and
configuring lines A and B as digital outputs.
To start capturing data, click the Run button in the upper right corner. If the horizontal scale is such that it takes more
than 200 ms of data to fill the lower SLO-scope pane, the data will continuously stream across the pane. If the lower
pane displays 200 ms of data or less, the pane will draw all of its data at once when it has enough new data to warrant
an update (or, if triggering is enabled, when the trigger event is satisfied). In this latter time domain, you can enable
the persistence feature (check the Persistence checkbox) to cause the data on the screen to fade out over time when
the next update occurs. The Length parameter determines how long it takes for the data to fade. The upper SLO-scope
pane shows a summary of all of the data currently stored in memory. This is approximately 10 seconds of data when
running at 10 kHz and 5 seconds of data when running at 20 kHz.
To review the captured data in detail, click the Stop button (in the same place that the Run previously occupied).
When the SLO-scope is stopped, you can scroll through the data stored in memory by clicking on the portion of the
upper pane that you want to inspect or by clicking and dragging the cursor in the lower pane to pan through the data
more finely. You can zoom in and out by changing the horizontal scale, and you can inspect the data in the lower pane
