Since USB Host shield uses pins 11 and 12 to interface to Arduino, I had to move corrsponding LCD signals to pins 6 and 7 the rest of the connections shall be made exactly like in the tutorial.
I use standard 16×2 HD44780-compatible LCD display, connected similarly to one in Arduino LiquidCrystal tutorial. First of all, we’ll need Arduino board and USB Host Shield. Let’s talk a little bit about necessary parts.
DIY ARDUINO USB HOST SHIELD CODE
To keep the code simple, I intentionally did not implement any data processing, however, since Arduino sketch for the gadget compiles in just a little over 14K, there is plenty of memory space left for expansion. LCD is erased before outputting each new barcode by tracking time between arrival of two consecutive symbols. Arduino then outputs these symbols on LCD display. The operation is simple – when handheld scanner button is pressed, it scans the barcode and sends it to Arduino symbol by symbol.
DIY ARDUINO USB HOST SHIELD PORTABLE
A gadget that I demonstrate today is portable autonomous barcode scanner built using Arduino board, USB Host shield, handheld USB barcode scanner and LCD display (see title picture). As a result, many modern “not-so-human” input devices behave exactly like a keyboard including boot protocol support. When USB became popular, other keyboard-emulating devices, such as barcode scanners and magnetic card readers have been migrated from PS/2 standard to USB while keeping their keyboard-emulating property. Originally, HID boot protocol was meant to be used with keyboards and mice. In today’s article I will show practical application of HID boot device building a simple gadget. In real-life applications, it is often not necessary to implement each and every virtual function – only what is needed. However, samples were designed to demonstrate all features of the class and because of that, they are somewhat heavy. The beauty of boot protocol lies in the simplicity of device report – a data packet containing information about button presses and mouse movements. Sample sketches demonstrating sending and receiving data to one of the most useful HID device types – boot keyboard/mouse, has been released along with the library. It's just for test the USB Host whether work all right and control a LED.Scanning barcodes using Arduino and USB Host ShieldĪn addition of Human Input Device Class support to USB Host Shield library 2.0, announced several days ago allows using powerful and inexpensive input devices with USB interface in Arduino projects. The following code was created by stripping down demokit.pde sample ADK sketch from non-essential code. Step four: By the first of Slider Button to control the LED.

Then connect the material.Ĭonnect the Android phone to USB=Host, the DemoKit will skip to the menu as below, and then check the "OUT" button
DIY ARDUINO USB HOST SHIELD INSTALL
And then install the APP of DemoKit to Android, the patth is ".\ADK_release_0512\app\bin\DemoKitLaunch.apk".
Here we just used the v1.0 library for test. Get the USB-Host-Shield-Library from USB Host Shield Library 1.0 or USB Host Shield Library 2.0. Note the USB_Host_Shile library in adk_release_0512.zip just suit for Mage2560, If you use such as Arduino Duemilanove or UNO, you need the modified library for it. Need you put "AndroidAccessory" and "USB_Host_Shield" library to x\arduino-0022\libraries\. The ADK package contains the firmware for the ADK board and hardware design files for the ADK board and shield. There are a Android of v2.3.4 or above(we used Nexus S), USB Host Shield, Arduino main board(we used Freaduino v1.0 with ATMega328(100% Arduino compatible), a 5mm Blue LED and a Power Supply.
DIY ARDUINO USB HOST SHIELD BLUETOOTH
This means you could use your Arduino to interface with and control any USB slave device - thumbdrives, digital cameras, bluetooth dongles, keyboards, mice, joysticks, MIDI, and much more!Ī simple demo of Control LED with Android and USB Host USB Host Shield is an add-on board for Arduino development platform and contains all of the digital logic and analog circuitry necessary to implement a full-speed USB peripheral/host controller with your Arduino. No more SPI re-wiring and code modifications – just solder included stackable connectors (2×3 ICSP connector’s female side should be facing down), plug and play! We recommend assemble with our Freaduino v1.0 with ATMega328(100% Arduino compatible). It's compatible with almost Arduinos – not only UNO and Duemilanove, but also big Mega and Mega 2560 work with Standard variant of this shield out of the box. If you are interested in Google' ADK(Android Open Accessory Development Kit), but Feeling ADK Developer Mage2560 is too expensive.
