Before You Start:

• Overview And Setup
• Barcode Recognition Function Guide

1.1 Recognize Barcodes and Output Data

Under the Barcode Recognition function, HUSKYLENS 2 can recognize barcodes in the image. The program can retrieve data of the barcode closest to the crosshair and output via serial. The readable data includes: barcode ID, barcode content, barcode width, barcode height, and X/Y coordinates of the barcode center.

The sample program is as follows.

Click Upload in Mind+ and wait for completion. Then enter Barcode Recognition via the touchscreen.

When a barcode is detected, HUSKYLENS 2 highlights it with a bounding box and displays the decoded content. Open the serial in Mind+ to observe related data of the barcode closest to the crosshair.

Result:Unlearned barcodes default to ID = 0, and the content matches the screen display.

Result: For learned barcodes, the ID and content match the screen display.

1.2 Count Total Barcodes and Output Data of a Specified Barcode

When multiple barcodes appear, the program can count the total number and retrieve data of a barcode with a specified ID (ID=0 for unlearned; learned IDs assigned in learning order).

Result:All detected barcodes appear in the serial output (both learned and unlearned), including total count and data for barcode ID = 1.

1.3 Barcode Recognition Block Description

block	description
	Retrieve barcode recognition data once.
	Determine whether any barcode is detected.
	Get data of the barcode closest to the crosshair: ID, name, center X/Y coordinates, width, height, decoded content.
	Get the total number of detected barcodes, including learned and unlearned.
	Get data of a specified barcode when multiple are detected.
	Determine whether a barcode with a specified ID exists. (ID=0 for unlearned)
	Get the number of barcodes with the specified ID.
	Get related data of barcodes with the specified ID.
	When multiple barcodes share the same ID, get related data for one of them.
