So, I have finally decided, that i want to make a project with my Arduino Nano, that was laying on the shelf. The project should be a keyboard for my laptop. But after reading few posts, I see, that I should use the V-USB library, because nano does not support HID protocol. I have found a manual, but I do not understand it. Any help where is your project's firmware source code directory? Or how to make sure that makefile contains rules to convert *.S and *.c? And the last, where is firmware's Makefile directory?
Manual: Simply copy the entire usbdrv subdirectory into your project's firmware source code directory. Then edit the firmware's Makefile and add the following object files to your binary:
usbdrv/usbdrv.o
usbdrv/usbdrvasm.o
usbdrv/oddebug.o
Then make sure that your Makefile contains rules to convert *.S and *.c to object files.
I´ve tried, but I cannot import it into my Arduino IDE.
