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: It can acts as generic USB host breakout (with any microcontroller. After soldering together (as seen on second picture) is a slight bigger than Arduino Pro Mini itself. Shield is based on MAX3421E, which works as USB host (computer ports do work in this mode). The final structure should look like this: USB Host Shield For Arduino Pro Mini 3.3V. 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:
ARDUINO USB HOST SHIELD ADAFRUIT INSTALL
*Recognized 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. Please contact us to get full sample codes: the RT830c automatically detects and reads bar codes. PrintHex(buffer.c_str(), buffer.length()) If (buffer.indexOf(response) != -1 || buffer.equals(response)) Upload the below sample code rt830c_test_demo.ino to Arduino UNO.īool check_response(unsigned long timeout, String response) For more details, please refer to the full user manual.
