I've just purchased an Opticon F31 2D barcode scanner for use in a cocoa mac application as a USB Serial device.
We've used the NLV 2101 and scanned the C01 barcode from the universal manual which works, but the F31 always gives back a bad scan error and stays in HID mode (acts as a keyboard). Have I bought the correct scanner or is this one faulty?
It turns out that the command code to switch the scanner to VCP mode doesn't work on the F31. You need to use the barcodes on the following URL to switch between VCP and HID mode.

Here's the problem: I want to press an external button attached to an Arduino, and I want that button press to translate into Windows as a keystroke.
My question is, is there a programmable device (I already own an Arduino) that can receive signals, and send them over USB to my computer which will understand it as a keypressExample: Button press acts like hitting the S key on my keyboard?
There are three (four) possibilities:
First Get an Arduino Leonardo (32U4 architecture) - there are HID drivers (so windows recognizes the hardware - short explanation: The Arduino LEONARDO is an integrated USB HID Arduino board. Ideal for projects requiring the board to behave (act) as a USB human interface devices = HID).
Two Use any other Arduino and install Processing with the relevant modules. Write code on both and use Processing to translate to windows.
Three I've seen some more or less working implementations.Example 1Example 2Example 3 Scroll down and you will see a picture of your button solution including code.
(Four) This requires also windows programming skills. Write an usb "driver" a translating engine for I/O between Arduino on usb and acting like a virtual (e.g. touch screen) keyboard. Thats the hardest way to go.
I would like to learn how a pc comunicate with a usb device and vice versa.
For example i have a Logitech Attack3 joystick connected to my pc, with its driver installed. I create my project with a trackBar or progressBar and would like it moves as i move the stick on the joystick. Could you please link something were i can study how to do this. I tried to search the web with no results. Thank you
I am using Odoo version 10.0 and I have got Point of Sale module installed. I have connected receipt printer and barcode scanner with the POS Box and they are shown connected in the status page (192.168.x.x/hw_proxy/status). In the Point of Sale settings, I have indicated the IP address of the POS box and checked 'Barcode scanner' and 'Receipt Printer' options.
Receipt printer is working fine, however, the problem is that whenever I scan the barcode, I am not getting any response. Where am I going wrong?
I followed this link answer given by #Ahmed Shoman. I changed the configuration of my barcode scanner to USB Keyboard. So accomplished this by scanning barcode in LS-2208 manual page number 109 (HID Keyboard Emulation).
This is my first time posting here. I hope you can help me with this guys.
I am trying to use a Generic RFID USB hardware (R10D-USB)in my VB .Net project.
Problem:
It seems that this RFID-USB hardware looks like it is being read by my computer as a Keyboard device. It is producing Keystrokes.
In Device Manager, it is being known as
Keyboards
----- HID Keyboard Device
also as
Universal Serial Bus Controllers
----- USB Composite Device
Now, whenever I tap an RFID in the RFID Reader. It produces Keystrokes like Keyboard.
It is typing literally as if your typing on your keyboard. So Whenever I tap an RFID to the RFID reader it would write something even in Notepad.
Concern:
What I am looking for is, is there a way I can sort of like assign it to a Port and only works unless it is being read by my VB form.
in other words, it would stop acting like a keyboard and be disabled to all other programs and activities except the program that I will make to catch all of its Keystrokes (can work on background).
I am running windows 8(64) and am using Arduino Uno for the first time. I downloaded the IDE and plugged in my arduino. I'm using a IMU 6050 Accelerometer Gyroscope Breakout Board and am using the first MPU6050 DMP6 example program to test it out. I open up the serial monitor and instead of displaying the text like it should, it only displays a line of weird symbols(cross,box, y with a dot over it, Germanic alphabet letters) and then nothing else. I am brand new to ardruino and can't figure out what to do. I checked the Uno driver and everything is fine. All the arduino files are downloaded, I have downloaded both the MPU library as well as the I2C library. The Uno is blinking, the data is coming through (I think) for some reason its just not displaying right. I have been searching all over the web for days now and I can't find anyone with the same problem.
It sounds like a baud rate mismatch issue. Try to change the baud rate from the drop-down and make sure that it matches the rate passed to Serial.begin in your sketch.
