When streaming timestamped data over DGI from an Xplained Pro or Curiosity Nano kit,
too high data rates can lead to buffer overflows and reduced stability of operation.
This also applies to Debug GPIO and Power Data. The Data Visualizer UI will display
a warning when the kit or tool indicates a buffer overflow condition. The sample
rate at which buffer overflows are likely to occur depends on the PC and the system
load. For GPIO it could be down to a few kHz sample rate at system load. For other
interfaces it is typically higher.
To get the expected result when streaming data, it is important to configure the
target system properly. Study the user guide of the target development board or tool
carefully as it can contain important information.
The standalone MPLAB Data Visualizer may interrupt an active debug session on a
development kit on start up. If a debug session is in progress in MPLAB X on a
DGI-enabled kit when MPLAB Data Visualizer standalone is started, the debug session
may be interrupted and the kit might not show up as a connection in the standalone
version. The workaround is to close MPLAB X and unplug and plug in the kit. For
simultaneous debugging and data visualization, please use the MPLAB X plugin version
of MPLAB Data Visualizer (Window>Debugging>Data Visualizer).
