the setup "startup" printed alright, but then the code started entering into the incoming bluetooth signal despite the bluetooth card being inert, as well as printing a lot of blank spaces. The code compiled correctly, but upon uploading the whole process broke. I expected the code to do one, then the other, and produce similar results.

However - check the manual for your barcode scanner: it may well have a RS-232 mode that it can be switched into (may. So you need a USB host shield to act as that host. If( rcvd ) //if( Usb.getUsbTaskState() = USB_STATE_RUNNING.Ĭombining the 2 codes looked easy in theory, I just added all the neccessary configs and then added the USB section after the bluetooth checks with a small pause. In USB you have hosts and devices.A device has to connect to a host.Your FT232 is a device.The barcode scanner is a device.Both of them need to be connected to a host for them to do anything. You could use this shield with Arduino Boards that have the same form factor as the Arduino Uno, like Arduino Uno Wifi, Arduino Mega, Arduino Due, and other Arduino clones as well.
This shield supports USB 2.0 full/low-speed operation. * it it set to 64 (largest possible max.packet size) here, can be tuned down This shield lets you communicate with other USB devices such as a barcode scanner and a keyboard. * buffer size must be greater or equal to max.packet size */ Serial.println("OSCOKIRQ failed to assert")

While (!Serial) // Wait for serial port to connect - used on Leonardo, Teensy and other boards with built-in USB CDC serial connection Satisfy the IDE, which needs to see the include statment in the ino too.ĮrrorMessage(PSTR("SetControlLineState"), rcode) ĮrrorMessage(PSTR("SetLineCoding"), rcode)
Basically 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. PortBluetooth.println("secret code acknowledged: opening all doors, sending current loaded numbers to serial") For the USBdesc example appears in the example menu, you must first attach the USB Host Shield 2.0 library in the libraries folder of Arduino software. If (portBluetooth.available()) //Here We're checking whether data is available or notĭata = portBluetooth.read() //Data received Serial.begin(9600) //Sets the baud for serial data transmission (Bits Per Second) Void setup() //The setup function will only run once, after each powerup.It initializes and sets the initial values I have a standard Arduino UNO and a USB host shield from CircutisHome with the following specifications: CircuitsHome 2010 USB Host Shield rev.2.0.

software serial #1: RX = digital pin 10, TX = digital pin 11 I’m trying to use the USBHIDBootMouse.pde example from the GitHub repository. char data //Recived data will get stored in this variable This one detects if an admin code was sent and triggers a response. Here is a part of the bluetooth control code with setup. After a bit of fiddling with it, I managed to make a code which was able to receive the data sent using an ACM and then print it to the Serial port (connected computer) for debug purposes.ĭoing so separately resulted for both codes working properly, but when I attempted to do so, the code stopped working. Note: the barscanner works well when i use it with the notpad.I am trying to get the ACM/USB to work in conjunction with the software serial port of the bluetooth using an arduino but combining both codes causes both functions to break.Īt first, I developed the code for the bluetooth part of the application, and I was able to properly send and interpret commands sent through a software serial (on pin 10 and 11).Īfter that, I added an arduino USB shield in order to connect it to an MRC12 USB barcode scanner. I use arduino mega2560 + usb shield host + lcd + barscanner made in china When i use mouse or keyboard instead barscanner ,it is OK and there is a data in serial mointor and lcd. The compile and the upload going well after i have modified the file hid.h to usbhid.h and added USB_ toīut the barscanner doesn’t work, it is beep but no data over serial monitor or LCD. Keyboard or mouse can be connected to Arduino with the shield, wireless communication can be done with bluetooth dongle, you can connect to barcode reader. I have downloaded the project (Arduino code modified – Bar Code Scanner and USB Host Shield.) from but it didnt work…
