To give it a kick start I downloaded the library USB_Host_Shield_20.
If the library linked on the official Arduino site doesn't work, then it should mean i'm using it wrong.I bought a board last week. Then what would the problem be ? I'm helpless here. This means the keyboard's power requirements shouldn't be the problem. The results are : the Arduino Uno r3 uses 60mA, the keyboard uses 60 mA, connecting to the serial port uses 40 mA (much to my surprise). When using USBHidBootMouse.ino with a mouse, movements & buttons are perceived and print messages as intended.Īlso, it is recommended to use external power supply while working with HID devices – I’ve seen many devices which would refuse to function when Arduino receives power from its USB port only.ĮDIT : I tried to test if the power was the issue, so I used a 5V generator with intensity measurement. I've tried three keyboards, all of which work properly when connected to the computer. Tests show that SetReportParser exits with 0. Upon init, only Start is written to the Serial Monitor. I am powering the Arduino Uno r3 + USB Host Shield via USB. I've connected the USB keyboard to an Arduino USB host shield attached to an Arduino Uno r3, and I am using the example HID sketch (USBHIDBootKeyboard.ino) provided with the USB Host Shield libraries : I'm a day 1 beginner to Arduino, and I am trying to obtain input from a USB keyboard.
