Overview

Signal Processing Resource Center » Vision Development Module Image Processing Examples » 2D Barcode

This example illustrates how to use the 2D barcode VIs. There are two VIs for reading 2D barcodes, one is for DataMatrix and the other is for PDF 417. There are several types of DataMatrix barcodes that are supported including ECC 000-140, ECC 200 as well as various cell shapes and barcode shapes. Run this VI and select the barcode type you would like to read. You can adjust the delay to slow down the execution.
