collectData

Collect captured data from FPGA to host in nonblocking mode

Since R2024a

Syntax

capturedData = collectData(hub)

Description

capturedData = collectData(hub) returns the captured data from an FPGA to the host machine in nonblocking capture mode. hub is a customized data capture hub object.

Note

The collectData function is not supported in blocking capture mode.

Input Arguments

hub — Data capture hub object

dataCaptureHub object

Data capture hub object that interacts with each data capture IP, specified as a dataCaptureHub object.

Output Arguments

capturedData — Captured data

structure

Captured data, returned as a structure that contains structures for each connected data capture IP. Each such structure contains a field for the Capture_Window signal, a field for the Trigger_Position signal, and a field for each signal obtained by FPGA data capture. The captured signal field is a vector of Sample depth values for each signal requested for data capture at generation time. The fields of the structure have these signal names.

• Capture_Window — This signal indicates the current capture window.

• Trigger_Position — This signal indicates the position of the trigger detection clock cycle within a capture buffer.

• All remaining fields — The signal names you specified at generation time.
