Hi,
I am trying to design a simple PS/2 keyboard interface for Nexys3 board. The design should just recognize some scancodes and turn on an LED and another LED to show connection of keyboard with FPGA.
My design is not working and what I dont understand is - why a PIC microcontroller is provided? Can I not just directly use the keyboard data and clock inputs without using the PIC controller for my design. I thought I should be able to implement the design on FPGA and use the PS/2 inputs directly. But its not working at all.
Nexys3 uses USB HID port for PS/2 inputs.
It would be great if someone could help me with this. Thanks a lot
