Diagnostics Status Bar

The diagnostics status bar is always visible at the bottom of the ViewPoint application window and provides insights into the current data stream, including a compact summary of current performance.

Connected / Disconnected shows whether the primary serial connection is active.

Mode shows the current update mode. Continuous commits data as it arrives, while Frames commits data at frame boundaries. None appears before a mode has been selected or when no active mode is available.

FPS shows how many new-data frames are being drawn per second. This measures rendered data updates, not idle screen redraws.

Drop/s shows completed frames per second that were not drawn before newer data arrived. In Continuous mode this label changes to Superseded/s, because older data may be replaced by newer data as part of normal continuous streaming. Superseded is not considered an error.

Points/frame shows the total number of data points in the most recently completed frame across all traces.

Bytes/frame shows the number of raw serial bytes received for the most recently completed frame before parsing.

Uptime shows the elapsed time since the current connection started.

When a receive or parsing issue occurs, the status bar replaces the normal per-frame fields with issue-specific indicators:

RxDrop/s replaces Points/frame when incoming serial data blocks are being dropped because the receive queue is full.

ParseErr/s replaces Bytes/frame when incoming data blocks are being discarded because parsing or processing failed.

Values that indicate a problem are highlighted in the status bar. If the issue stops, the bar returns to the normal Points/frame and Bytes/frame display.
