    Hi Davaraj,

    Let me know what software and version you are using. This will be useful to analyze your issue.

    I only could to guess how to solve your issue without schematics, but if the keypad is presents in the /dev/input/... folder it could be opened like standard input device and the keypad event could be read from it.
