9.1 Data Streaming

SPI over DGI

If the data waveform doesn't match expectations or can't be decoded by the Data Stream Decoder, try enabling “Force synchronization on CS.” Sync issues are especially common when starting a debug session on an Xplained Pro development kit and then streaming over SPI from the same kit.

Plotting Resources

If your machine is having trouble plotting multiple data streams, such as voltage, current, and power:

• Stop the data stream when performing analysis.
• Zoom out on the time plot while live data is scrolling.
• Select fewer plot sources by using the controls on the right pane.
• Remove one or more plots.

Each of these suggestions cuts down on the system resources required.
