I need to interface matrix keypad with CY7C64215-56LTXC and send the detected key over USB. This should be PC compatible keypad.

Is there a sample code that reads key from keyboard continuously and sends it over USB for this device ( CY7C64215-56LTXC ).

keyboard is custom made whose rows and columns are connected to GPIO's of CY7C64215-56LTXC.
