In this solution, the scanner is set to USB HID KBW mode, and the Arduino recognizes the scanner as a USB keyboard simulation device. Serial.println("OSCOKIRQ failed to assert") Serial.println("Please set the scanner to USB CDC mode") 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) 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 you will like to open.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: Recognized as a 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. RT214 set to USB CDC mode, scan the following Setting bar code. Follow the steps as below:Ĭonnect the RT214 scanner to the USB port of the Arduino USB host shield through a USB data cable. In this solution, we connect the OEM barcode scanner to Arduino via USB host shield, and firstly we need to set the scanner to USB Virtual Com emulation mode, and the Arduino recognizes the scanner as a USB CDC device. Void read_response(unsigned long timeout) # For example, the Data for the Enable Code 11 is 1 (see Example 1 of Chapter 1).Ĭonst char *Prefix = "\x7E\x01\x30\x30\x30\x30" # The value for a feature or parameter setting, identified by the Tag and SubTag. # For example, the SubTag for the Enable Code 11 is ENA (see Example 1 of Chapter 1). # A 3-character case-sensitive field that identifies the desired parameter within the tag group. # For example, the Tag for the Enable Code 11 is C11 (see Example 1 of Chapter 1). # A 3-character case-sensitive field that identifies the desired command group. # “#” means temporary setting which will be lost by removing power from the scanner or rebooting it. # means permanent setting which will not be lost by removing power from the scanner or rebooting it # Prefix Storage Tag SubTag means integrant while means optional data.
