You should see the word ‘Start’ and then see the dongle running two commands: setting response data and starting the advertising.

Basically what Oleghe Mazurov did in his code was to take the communication code of a USB keyboard, he make some modifications to the bar code reader and adding LCD control code.

Open up the ‘Arduino Uno Viritual COM Port’ with a serial terminal emulation program like TeraTerm, Putty or CoolTerm.Serial port Setup:.In Arduino IDE click the upload button to upload the project to your Arduino.Search for USB Host Shield Library 2.0 and click ‘Install’.In Arduino IDE choose Sketch>Include Library>Manage Library.(For information on installing libraries, see: )

4.2 Downloading the USB Host Shield Library 2.0Įither download the Library from Here ( ) and place the folder into your libraries folder inside your Arduino folder.

How to setup project 4.1 Downloading the project from GitHubĮither clone the project, or download it as a zip file and unzip it, into your Arduino folder. You must also apply a jumper from pin D7 to RESET.Ĥ.With the SparkFun board, it seems like you MUST supply external power on Vin or the barrel jack.A BleuIO dongle with firmware version 2.1.0 or later ( ).Using the example project 3.1 What you will need When found, we just print out “>” or “>” to the terminal. In this example, we are explicitly looking for BLE connection or disconnect events. We also store the latest data from the dongle into the dongle_input buffer and run it through a simple “parser” to showcase an easy way of how you can react to events and have the Arduino do something. If( rcvd ) //if( Usb.getUsbTaskState() = USB_STATE_RUNNING. Memset(dongle_input, 0, sizeof(dongle_input)) Rcode = Acm.SndData(strlen((char *)START_CMDS), (uint8_t *)START_CMDS) If the buffers have received any data, we print it out to the serial terminal connected to the Virtual COM Port. The largest possible max.packet size for the function Acm.RcvData() is 64 bytes, so to accommodate the amount of data we will receive, we are using three buffers to receive the data from the BleuIO Dongle. This project based on the ‘acm_terminal’ example in the Host USB Shield Library 2.0
3 with SparkFun’s USB Host Shield (DEV-09947) for this example. It will then act as a terminal, taking input and sending data to the Arduino Virtual Com Port. When a BleuIO Dongle is connected to the USB port, the BleuIO Dongle will start advertising. I also occasionally help out on the forum there, too.The project is a simple example showcasing a quick way to setup an Arduino with a USB Host Shield as a USB CDC Host capable of communicating with the BleuIO Dongle. (I'm not affiliated, just a very satisfied and happy customer. This RAM appears as ordinary memory from address 0x70000000 upwards, so you can use it for your own data without worrying about bank switching or that kind of nonsense. (It's a really powerful Cortex-M7 microcontroller from NXP.) With one PSRAM chip ($2 USD) soldered to SMD pads on the board, you can add 8 MiB of RAM and you can use up to two of those PSRAM chips, if you find you need lots of RAM. Teensy 4.x has 1,048,576 bytes of RAM, and can run at up to 600 MHz. Teensyduino developer, Paul Stoffregen, is a frequent contributor to Arduino (authored many common libraries et cetera), and I've found the Teensy forums useful. Biggest differences are in fast I/O port access (instead of PORTD etc., you use digitalWriteFast() like in standard Arduino, digitalWrite() works too), interrupts, and timers: Teensyduino has easier interfaces for using all those.
Of course, you'd need to port your Arduino project over to Teensyduino, the add-on for Arduino for Teensy support. If using external power, note that the board does not have diodes, so you'll need to cut the VUSB trace (as described in the Teensy card) to make it externally powered only or use an USB cable with the +5V line disconnected to connect the Teensy to your development machine while externally powered. Note that you can connect the main USB connector to your development host while the barcode reader is connected to the Teensy USB Host connector, as long as the barcode reader doesn't require too much current (keeping the maximum current from the development host via the USB bus under 500mA). I also like to get the Ethernet kit ($4 USD) just in case I want to use the hardware 10/100Mbit wired Ethernet connection also.

I'd suggest a Teensy 4.1 (about $27 USD), plus the USB Host connector (about $3 USD, only need to solder standard 4-pin 0.1" spacing pin header).
