DigiKeyboard is not compiling

I'm trying to emulate HID keystrokes with a Digispark Kickstarter. For this I use the library DigiKeyboard. When compiling my simple sample code in the arduino IDE, I get the following error:

exit status 1

Compilation error: conflicting declaration 'char usbDescriptorHidReport [22]'

Sorry, some parts are in german. That was the original output.

I tried to define the variable usbDescriptorHidReport as const. I also removed the variable completely, which didn't help.

Does anyone know how to fix the bug or are there better libraries?

Solution

  • Use the library from https://github.com/ernesto-xload/DigisparkKeyboard/blob/master/src/DigiKeyboard.h instead of the original from https://github.com/digistump/DigisparkArduinoIntegration/tree/master/libraries/DigisparkKeyboard.
