Related to Keypad Driver ....

Hi all ...

If any of you have worked on key pad driver could you please guide me how to write the same as in the most standard form ...

I have a CPLD from Whre i have to read the key physical status (debouncing logic in CPLD itself) on interrupt this i have to pass to the application which ever is using keys for its operation and control ....

The concern is this ...

What could the best way of passing the virtual key status to the application and how it is done in linux drivers ???? How should i make the API waiting for Key event and Getting Unblocked ???? Can i make the API as a thread waiting for signal ??? The same API application could use ... How is it done in Standard Keyboard Drivers ???

A code snipped or Documentation would really help me ...

I am not sure what way i should proceed ...If any one implemented a Keypad driver or can suggest your experience

Thanks in Advance ...
