Satisfy the IDE, which needs to see the include statment in the ino too.ĮrrorMessage (PSTR("SetControlLineState"), rcode) ĮrrorMessage (PSTR("SetLineCoding"), rcode) Now you should be able to open all the examples codes by navigating to “File>Examples>USB_Host_Shield_20”, and then select the example.įor more information please visit the following sites: The final structure should look like this: Now move the “USB_Host_Shield_20” directory to the “libraries” directory. Open that directory and create a directory called “libraries” inside that directory. There you will see the location of your sketchbook. Now open up the Arduino IDE and open “File>Preferences”. Then uncompress the zip folder and rename the directory to “USB_Host_Shield_20”, as any special characters are not supported by the Arduino IDE.
Please see the following page for instructions:įirst download the library by clicking on the following link: Solution 3: Connect the 2D QR barcode scanner via USB interface ( for RT870) The RT830C without its own glass window, if you prefer an embedded barcode scanner with its own glass window, then you can choose our RT870 and use this solution: use an Arduino USB host shield as shown below. Please contact us to get full sample codes: as USB com port device on the computer.įirst, install Arduino IDE version 1.6.2 or newer, then simply use the Arduino Library Manager to install the library.
