NIOS USB Keyboard App ?

Is there an easy (... or known) way to add to a NIOS device some USB Keyboard functions (standard 101-key USB Keyboard accepted by any USB HID class driver) ? I guess its a low-speed USB 1.1 ...

Easy..hmmm...no.

Depending on your quantity and requirements I guess. You can get free IP from www.opencores.org for USB.

I would say that if you have only a few units to build to rather go for a ps2 keyboard (also easy IP to implement).

I am just thinking of all the trouble you are going to have to face writing a USB master interface to read the keyboard. BUT if you are going to do this for a mass produced product then go right ahead. USB is the face of the future. PS2 will die out soon.

BTW. If you find an easy solution for USB keyboard and/or mouse let me know as well.
