Bar Code Scanner Control with Arduino USB Host Shield.
Detalles en / details in:
www.electroing...
Solucionado: no leía el código de barras, lo que hice fue modificar la línea 31 del archivo "Leitor.h", le cambié el "19" por "13".
Así quedó: if(key == 13){
Code A0 -----------> DATA + USB ?
I always find error in . I have searched the library directory but i have not found hid.h. I have searched the comments field but there are no answers that can help. Please help me, how can i solve this...
I downloaded the USB shield library (mega.co.nz/#!bABVUTyA!JfhEvVZ4wfcG1MzS3ccBL7SY5uiai1kUy-h4bYBbKJI), but everytime I try to use the USB_desc examples i get errors about undefined variables. Any ideas?

Why does every Arduino video have this Annoying crappy music? Better off with silence -
I wanted to buy this code but there is no payment method.
Is there any other option to get the code?
Nur Muhammad, you need a bar code scanner that not requiere driver
I did every thing in this vedio but no reading from barcode its just turn on but no number in lcd can any one help me?
#include : fatal error: hid.h: No such file or directory
Hola, intenté comprar el código pero no hay forma de pago para México, Ademas el apartado de contacto de la pagina no funciona
kindly add code in description.
I want to design a tool to make a qr code scanner, please help me.
Nur Muhammad, this is mega but you can use the code in arduino UNO, only you need verify the pin conection
descargue el codigo y me da un error
#include //Add to Oleg Mazurov code to Bar Code Scanner
.
como me puedes ayudar urgente
Ya agregaste la librería a arduino?
@@jucam de donde se puede descargar esa librería?
Hola . Estoy con un proyecto parecido .. si doy ok en la compra por 1 dólar me larga el código que usaste ?? Quería agregarle un módulo relee con 8 relee ..
hy ...
so thanks full ...
its so great projetc...
its work properly..
al compilar USB_desc me salen los siguientes errores: alguien sabe como corregirlos.

I have my barcode scanner tied to the circuit that cuts the power to the scanner when the label maker prints the label. Once the label is removed the power is back on and the barcode scanner and key board will turn on. My challenge is that the Barcode scanner doesn’t come back instantly after you remove the label and takes 11secs to turn back on. Do you know a setting or a device that can help me eliminate this delay!
For code qr?
una pregunta sirve con los codigos de barras de los documentos de identidad?
Hello.. i am using a datalogic qw2100 scanner. it is configured to a autosense scan..
when i plug my scanner to the usb host.. the scanner just light on(green led)..
whats the problem? can you help me please??
Hi. I'm currently working on it and the revised code worked. But I have 1 big problem. When I plug the barcode scanner it doesnt seem to work. But when I plug it in a pc, it worked fine without a driver. The LCD displays "Ready" as stated on the program. But my barcode scanner doesnt seem to establish a connection with the host. Please help.
Agrego el programa para validar os tres codigos que indica la pistola lectora, pero veo que ni me energiza la pistola, qe debo hacer en este caso
hello, can the barcode device be converted into an RFID module? if so how to do it? thanks
Are you using arduino uno?
Can scan qr code?
i have a project like that but, with all that i need to transfert that barcode to RFID MF RC522 to write that code in the tag, so i want to transport that code to the RFID to make the writing not to the LCD
so is it possible ?
my friend can i convert the code to number (price) in Arduino ?
and do total for all price of product ?
shall i need to cut SS jumper? Pin 0,1,2,3,5,6 is used for lcd .
sir i have a barcode scanner which states Interface Type: USB,RS232,KB.
can it work with the same code?
please help as soon as possible its really urgent.
I really enjoy your code, I don't fully understand what it does , but maybe you can help me with my problem. I need to read from the barcode scanner and place the value into a variable that I can use for a switch/case statement.
Moises Beato in the file code, you need to verify when the scanner finish to send data. In line 86, on file code, the arduino print each number from scanner, you need to collect all number in a string variable.
Thank you
Electroingenio
Hi, how i can collect all number that i have scan into a string variable from line 86??
use "key" variable, I not do it, but try
+Electroingenio I don't understand what you exactly meant with that. Could you please give us a little example that you have tested and works?
I cant visit the website, it says "Error establishing a connection to the database"
Can you make a barcode based attendance system pls its code?
Amigo buenas noches, tengo un problema, conecto mi lector codigo de barras (x-718 wired laser barcode scanner) cargo un codigo pero no me energiza la pistola, como puedo validar primero si la salida me esta alimentando la pistola o unicamente se energiza con el codigo correcto?
Is it compatible to a Nucleo Board?
Hi, i follow this video steps by steps but it appears error: ‘HID_PROTOCOL_KEYBOARD’ was not declared in this scope, why? ?i use arduino mega, software version 1.6.6 and host usb version 1.1.1
+Irene Kong You need to use USBHostShield20master library and compile with arduino 1.0.5 r2
I had problems compiling, but I deleted the line HIDBoot Keyboard(&Usb); and it worked
Do you also delete the line Keyboard.SetReportParser(0, (HIDReportParser*)&Prs); ?

+Jorge Ignacio Arzave Vazquez tienes un problema con la ruta de las librerias USB, adicionalmente te recomiendo compilarlo en la version 1.6.0
Hello,
Sorry to keep spamming with questions. But I need help quite urgently. I went ahead and picked up the same USB shield, in the hope that this would solve all problems. As it appears, it doesnt quite.
The code uploads fine and when I open the serial monitor i see the word "start". When I scan my barcode, i get the customary beeping sound from the scanner, but there is nothing printed on my screen.
I just picked up the shield today and plugged it in immediately for use. Am i required to do any specific configuration?
The device intf. class and subclasss all match, so I realy dont know what I'm doing wrong.
I'm using your exact code as well.
Please please help!
Thank you
hello, see this video th-cam.com/video/U4eFLdpyRDQ/w-d-xo.html , and download app from www.electroingenio.com/download/ to test other way.
n now i tray to develop more.....
the problem is, key is char data , so when i tray to compare its not work properly
where you buy the barcode scanner
Hi, can this be used to operate a motor only if this barcode info matches with a stored info ?
where can i get the source code. i really need that
can u help me? why my usb-desc didnt show their a same like yours
me da este error

Hi, i'm looking for Hid.h library, Where can i find it?
i have the same project, and i did all the same thing, but i have an error ""fatal error: hid.h: No such file or directory #include "" . i don't know what to do to correct this ... any help pls and thx
You need to organize the directory that contains this file. This is in the library. This error comes up when you have located the files in a wrong way into the arduino libraries directory
how to read value and compare with fix code, and judge it OK (same) or NG(diffirent)?
tengo Intf. Subclass "0" .. en circuits@home, dice que tiene que ser "1", pero si en caso es 0 si se puede solo que es un poco mas dificil, pero no encuentro donde explica eso, podras ayudarme con eso si en caso sabes ?
Hola que tal; cuando compilo el código me sale un error relacionado con la variable Keyboard, me dice que anteriormente ya ha sido declarada, específicamente me da este error:
sketch_may03b:21: error: conflicting declaration 'HIDBoot Keyboard'

hi, i got problem when clicking USB_desc of USB_Host_Shield_2.0-master. when compiling it, it appears error : usb.ino: 3:17: fatal error: usb.h: No such file or directory. I use arduino version 1.6.5. How to solve it?
hello, I recommend you that erase the underlines and middle lines from folder USB host shield library and join all words of the file name.close the arduino and open again.
points too
Hi, the USBHostShield20master library is same with github.com/felis/USB_Host_Shield_2.0 ??
+Irene Kong is diferent in some things
+Electroingenio Is USBHostShield20master library same with library manager : usb host shield version 1.2.1 or 1.2.0?
Hola! podrías ayudarme? tengo un usb host shield y un arduino uno, al principio funcionaba y luego obtuve el mensaje de "OSC did not start" y no obtengo ningún tipo de lectura del puerto usb..y no encuentro el problema, agradecería tu ayuda si sabes como repararlo?
Hola, posiblemente el oscilador del arduino tiene problemas. Tu lo puedes cambiar, no es complicado, solo asegúrate de poner el mismo valor.
i use bar code scanner Motorola which consume 500mA and i am using arduino uno and this usb host" ram-e-shop.com/oscmax/catalog/product_info.php?products_id=2844 " which Max Current 500mA when Arduino is powered by a suitable power supply connected to the Arduino power jack and i connected arduino with adapter 12v ,1A and still cant run scanner any ideas !?
I have not work with there shield, sorry
similar issue. any luck?
Hi, I am unable to access the code from the circuits @ home webpage. I think the website is down now. Can you please please please help share the codes with me? Would really appreciate it. Need it quite urgently :/ Thanks a ton in advance!
same situation thank you so much
+Anisha Mathew you can download from my web, free
By using arduino 1.6.5, I got problem of compiling USB_desc of USBHostShield20master, prog_char does not name a type, after that, compiling the coding, unit8_t has not been declared.
tell me your Skype user
+Electroingenio Ring Kong or u give me ur skype user?
Does anyone know how to introduce the read code by the scanner into a variable?
I have tested many ways and it didn't work. I would like to receive some help, please.
+Eduardo Javier Jimenez Suero you need to send each character to string variable as vector.
i downloaded USB_host_shield_2.0_master at arduino.cc . But USB_desc's program had many errors. Can you take me true program of USB_host_shield_2.0_master?
Please reply me, Thank you

Hola que tal, que pasa si pago 1 dólar? Me mandas el sketch o que es lo que contiene la compra
Hi can you give me a detailed diagram of this?
hola buenas tardes serias tan amable de decirme que lector de barras utilizaste
bro give the program in discription.
Good day my friend. This is a great tutorial. i hope you can send me the complete schematic diagram of this. In your diagram, i cant find where the resistor is placed and its value. please reply fast. thank you in advance.
Jep Gallarde Thanks for your comment, here is the schematic www.electroingenio.com/arduino-en/bar-code-scanner-arduino-usb-shield-2/ and complete information.
Hi guy! I run into problem. It notify that "fatal error: hid.h: No such file or directory". Does anyone fix it?
Tùng Vũ you need to check your library directory
HOLA, puedo usar un BARCODE inalambrico???
Luis Anthony Fuertes Amaya este proyecto está desarrollando para trabajar con un módulo USB, no tengo la información de cómo sería con el inalámbrico
a mi me da este error OSCOKIRQ failed to assert con el ejemplo adk_barcode
I am making same project in my exam.. Can you just tell me components used in it and About Uses of this project..
Gaurav War same bro. Im using smart shopping cart project aswell
Ahmad Ammar Components???
Is there any sensor we needed to use. If yes. What kind of sensor.
Arduino uno
Usb cable
16X2 lcd screen
Barcode scanner
Can u email me. ahmadammar72@gmail.com
i am exactly using the same type of arduino usb shield and barcode
same program
bt its showing hid_protocol_ keyboard not declared in this scope
Sujith Kumar you need to check your library
hola es que ice todos los pasos como lo muestra y cuando cague la segunda codificación me sale un error `USB`does not name a type y no lo puedo corregir
Solo me sale el Start en el USB_desc
why i uploaded USB_DEC library into arduino with Barcode scanner but when turn on serial monitor there is no output file of the barcode reader like you?
You can not use the same serial port to communicate at the same time to serial monitor and the bar code.
So what should i do? Can you tell me. Thank you
I did exactly the same as the video instruction but there is no output file in the serial monitor. Just a "start" line that was all
Hi I'm a high school student and I have graduation project, so I want to ask you if we want to convert the code that the scanner reads into number like dates, how can we do that?
+GDVIP a barcode is an identifier that is associated with a database. For example, when a barcode in a supermarket you read, this code is searched in a database of products it sold that supermarket . Although a bar code of a product is as unique code assigned to the producer look this link: www.elfring.com/retail-barcode.htm without thier you can create your internal codes if you plan to use personally .
Estimado tengo un problema, resulta que pude leer todo sin problemas. El tema es que quiero a ese código asignarle un precio y bueno no se donde realizar el codigo, intente ponerlo en el loop, pero no me toma el codigo... ademas el codigo esta solo en una variable, o sea (char)key cambia 13 veces de valor, pero todos esos numeros me gustaria tomarlos y asignarle un precio.
Hi,
I have been having troubles using my barcode scanner with my arduino mega. The code complies fine, but it keeps stating the that the OSC does not start. Can you please help me with this? I am using a different (sparkfun usb shield) to what you're using. The barcode scanner satisfies the same communication protocol, int. class, subclass , so I don't think this is the issue. Will you please be able to help?
Thanks
Much appreciated!
i see this person has a simliar issue : forum.arduino.cc/index.php?topic=86612.15
he claims that "Olegs's library does NOT work with the Mega ADK,I have tried it again with the new 1.0 IDE
and his updated USB library for that IDE.
It compiles OK but it will NOT work on the Mega ADK."
any help would be greatly appreciated!
I have using Mega 2560, I dont`t know if work with mega ADK.
Hi, yes I use the same.
Do you think the difference in our shields might be the reason it is not working for me?>
Hola, quisiera saber si me podrias ayudar con un problema, el programa compila y lo puedo pasar al arduino, pero cuando conecto el lector de barras, el lector prende pero no sale la linea que scanea el codigo? sabras porque pasa esto ?
Si corro el ejemplo y no me aparece nada en monitor serial, solo aparece start y OSC did not start, que puede ser o necesito instalar otra cosa?
+Rosalinda Gonzalez Gomez verifica las librerias
Could you also use the shield as an USB host for your own USB device? I'm planning on making a gamecontroller, so can I wire the USB cable to the Arduino and have it communicate to any device that my controller is plugged in?
Yes, is posible, the next video use an PS3 control:
USB Shield Arduino + Servo Control PS3
what's scaner machine?
Se eu quiser implementar uma condição If. Tipo se o código for 837383837 . Executa tal coisa. Como faço? Qual variável uso?
nao consegui nem fazer ligar essa tranqueira
Boa tarde, pode me ajudar?
Thank you so much for helping me!!!
give me your programme please bro
Buena tarde amigo disculpa porque aparece el siguiente error USB_HID_PROTOCOL_KEYBOARD was not declared in this scope
te hace falta instalar la librería USB host shield
tengo el mismo problema y no me funciona y ya tengo la libreria
Buscala en los comentarios amigo es un archivo de mega usa ese, no el que esta en la descripcion eso me soluciono el problema a mi
Hola buen dia me surgio un problema
'HID_PROTOCOL_KEYBOARD' was not declared in this scope
podrias decirme como resolverlo
te lo agradeceria
+saul aguilar no tienes instalada la librería en el directorio correcto, por lo tanto el software no la encuentra
muchas gracias que tengas excelente dia
Hi what distance does this scanner read barcode
I am not sure, maybe 30cm
Hola que tal nuevamente, me surgió un inconveniente al querer realizar una aplicación con el código que leo, El problema es que el arduino constantemente esta leyendo el puerto usb y no puedo realizar nada en el loop.
Principalmente me idea es comparar el codigo de barras con una tabla interna y realizar una salida. Me gustaria saber si hay alguna forma de detener el usb cuando se termino de pasar todo el dato serie y habilitarlo nuevamente cuando finalice la tarea con el codigo que capture.
Estoy usando el if( Usb.getUsbTaskState() == USB_STATE_RUNNING ) pero todavia no logro entender bien su funcionamiento
Gracias y saludos
En el mismo loop, despues que termine de revisar el puerto USB, programas una funcion o puedes intentar introducir tus lineas de codigo despues de la linea 89.
bro .i had more error for this code. pls help me
Hi, do you have the HID library and all libraries required?, if so, make sure are installed correctly.
Hola. Mi pregunta es muy concreta: estos lectores de códigos de barras, ¿pueden leer en la oscuridad? Porque lo estoy pensando para un domo astronómico, donde el sistema debe saber constantemente en qué posición está el domo.
Hola Javier, no lo he probado en la oscuridad pero debería funcionar.

hello sir , i have a problem , i followed all steps but i get this error " exit status 1
'HID_PROTOCOL_KEYBOARD' was not declared in this scope " i try to use ide 1.05 r2 and with last version and it don't work can you send me code ?
you need to review the usbhostshield20 library and the code you can download from my website electroingenio.com/download
i can't download it i don't have a paybal accounte :/ i use the last version of usb_host_shield_2.0 send it plz to my email beng.med.amine@gmail.com thank you sir
all work fine just when i scan i get : *()!)ù&#)#@#!c but the barcode i'ts 8901057303231 :/
Ben Ghelima mohamed amine review the scanner configuration, speed of scan or similar
en este video que hiciste el código aparece en la pantalla derecha? Necesito exportar esta bares código en el Arduino para leer cualquier tipo de archivo. Para hacer un sistema de medición de producto que el código de barras.
es el que aparece a mano izquierda
hola!! tengo una duda solo se puede utilizar el codigo de barras mostrado en el video?? o se puede utilizar cualquiera? si se puede utilizar otro aparte del mencionado en el video tiene que tener algunas especificaciones o datos?
Te refieres al scanner?, en general funciona con varias referencias, pero tienes que tener en cuenta que al verificar los codigos de Class, Subclass y protocol sean como se indican en el video.
hola, tengo un scanner Symbol LS2208, al conectarlo y ejecutar el USBdesc no me muestra los datos que te aparecen a ti en el monitor serial, solo puros simbolos como garabatos, me podrias ayudar?
I downloaded the USB shield library, but everytime I try to use the USB_desc examples i get errors about undefined variables. Any ideas?
Moises Beato download this library file and replace yours: mega.co.nz/#!bABVUTyA!JfhEvVZ4wfcG1MzS3ccBL7SY5uiai1kUy-h4bYBbKJI
I got the library. USB desc still didn't work. But I still got the barcode scanner to work. Now, all I need is for the servos and steppers to move once I scan something... But nothing I put inside the void loop works
Moises Beato what happens is that apparently changed some things in the original library and not working well, so I attached the download link with the library that I used
what is the name of scaner machine?

existe algun lector infrerrojo de codigo qr? como los lector de codigo de barras pero para imagenes completas
hasta ahora no los conozco, no sabría decirte si existen. Lo que se es que el código QR esta diseñado para ser reconocido por una cámara.
+Electroingenio Recien buscando encontre unos en alibaba como QR code infrared reader, espero que sean lo que creo.
+Julio Nuñez excelente, me cuentas
Hola, queria agradecerte por el video, yo tambien tenia el error HID_PROTOCOL_KEYBOARD' was not declared in this scope, estoy con la versión 1.8.5 y la solución al error fue cambiar la version del USB HOST Shield Library a una más antigua (mediante el gestor de librarias del mismo arduino) y el programa funcionó correctamente.
hola me podrias ayudar con una consulta urgente?
Cual es la duda?
hola bro , acabo de solucionarla despues de 5 horas de informacion xd pero aprovecho y me atrevo a pregntar si sabes como enviar todo los digitos como un solo "caracter" y no como lo hace actualmentes el programas byte x byte(resumen quiero k dispare todo junto y no 1 x 1)
Eso no lo se, porque solamente pude hacer que el usb funcione, de hecho aparece los datos mediante el key dentro de las intrucciones usb y solo lo maneja "dato por dato" porque creo que es como si estuviese conectado un taclado: muestra en pantalla letra por letra que se va escribiendo. Tendrías que buscar una forma de convertir los datos que quieres después de la lectura.
ya lo consegui... ahora el trabajo es como enviarlo por xbee
no de deja añadir la librera que hagoo
Que error te sale?, recuerda que la libreria se debe añadir en la carpeta libaries del software Arduino
Entonces amigo, muy interesante el video, tengo una consulta,Tengo un arduino unoR3, estoy usando el Barcode DS9208 de Motorla este funciona a 5V a 500ma, tengo este shield usb (www.sparkfun.com/products/9947) segun el datasheet existe manera de que entregue 5V pero aun no he dado con el chiste solo tengo 3.3V en la salida al conector usb y no lo energiza como debe ser, me podrías dar alguna indicación, mil gracias
le pones la fuente de 9 voltios extra en el jack no se como se llama
Amigo como hago para que me lea el codigo de garras
Como bloquer la señal
