How do you scan a barcode? It's simple, you use our Barcode click.
Barcode click is compliant with a wide range of different 1D and 2D barcode protocols. Since it's equipped with a micro USB port it can work both as a standalone device and a standard Click board.
And for low-light conditions, Barcode click has two red LEDs, to illuminate the scanning area. As you can see, we thought of everything. Read the rest, and find out more about all the amazing features of this Click board™.
Barcode click - connection options
Barcode click offers two connection options: via USB or UART. This means that when you plug Barcode click into the mikroBUS™ socket it will be able to send and receive data from the host MCU. On the other hand, if you connect a USB cable to the micro USB port located in the middle of the Click board, it will be identified as one of these three things:
- A virtual USB port
- A HID keyboard device
A HIDPOS device
Lots of options and parameters on Barcode click are easy to configure. If you open the LV3296 user guide, you will see that all you need to do is read a specific barcode that is provided, and the configuration is complete.
For example, if you want your barcode scanner to be able to read ASCII characters, just turn to page 79 of the user guide. To set the desired start/stop character format, turn to page 82 and scan the barcode you see.
How to scan?
Barcode click can read barcodes from any angle, no matter how they are rotated. Simply point the scanning beam over the barcode, and you are done.
Barcode can scan the codes both from paper (a printed version) and from a screen.
1D and 2D barcodes - what is the difference?
1D barcodes also called linear and one-dimensional barcodes, are able to represent data by altering the widths and spacings of parallel lines. These are the type of barcode you have been seeing your whole life, in supermarkets, on the back of books and boxes, and well, on almost anything that you ever bought.
Two-dimensional or 2D codes, unlike 1D, have intricate patterns of dots, squares, and hexagons, and not just lines. In this way, they hold more information than their linear predecessors.
There is also a difference in the way they are scanned. 2D barcodes can be scanned from any direction, while 1D codes are scanned linearly.
