communicate with other USB devices, and supports USB HUB function. Download: USBHostShield2.zip, Version 2.0 (works with Teensy) USBHostShield1.zip, Version 1.0 (modified for Teensy) Only one version should be copied to your Arduino libraries folder.

The following video is a step by step of the changes that I have made in the code of Oleg Mazurov and description of the operation of barcode scanner. Arduino USB Host Shield board - Lets your Arduino support Android phones. The USB Host Shield, by Oleg Mazurov, allows you to connect other USB devices. The example to control USB keyboard also find it on the USB Host Shield library 2.0 with the name “USBHIDBootKbd”. If your code reader does not match the above information after verification, is posible that you may not implement the code that we work here, so is important to check with your example of USB Host Shield 2.0 library called “USB_desc”.įor the USB_desc example appears in the example menu, you must first attach the USB Host Shield 2.0 library in the libraries folder of Arduino software.īasically what Oleghe Mazurov did in his code was to take the communication code of a USB keyboard, he make some modifications to the barcode reader and adding LCD control code. Thanks to new interface layout it is now compatible with more Arduinos - not only UNO and Duemilanove, but also big Mega and Mega 2560 work with Standard variant of this shield out of the box. It is necessary to consider the recommendation of Oleg Mazurov in verifying the parameters of our device, which identify the CLASS and communication PROTOCOL as follows: Intf. USB HOST SHIELD Product Description: This is revision 2.0 of USB Host Shield. The largest possible max.packet size for.

The following is the code from Oleg Mazurov with the modifications that I have made to work with my barcode scanner and other different bar codes scanners:īar Code Scanner + Arduino Host Shield code This project based on the acmterminal example in the Host USB Shield Library 2.0. In this test I used the code that kindly shows us Olegon Mazurov on their website and I have made some modifications, because it did not work well for my barcode scanner “Datalogic QuickScan” and I have not found more information on the web about the use of barcode readers with the USB port connected to a separate host as USB Host Shield of Arduino. But it becomes a problem when the shield is pretty complex (like the USB Host Shield) and you have to use a library and the shields are not compatible with each. In the world industry, a lot of products are identified by barcodes, is one of the most effective methods to identify products, papers, stickers, among many other things, is for this reason that implementing a system for reading bar codes independent of a computer allows greater flexibility to these devices, is why I wanted to bring this little test that will allow many projects related to barcodes, be more flexible and portable.ĭeveloping an Arduino project with BarCode Scanner + Arduino USB Shield
