     here i an writing the algo which might help you out…

    *the switches are connected to a port of microcontroller(lets say PORTA)..

    *the port A is externally conncted to the pullup array…

    * as soon you press any key that particluar pin of portA goes low

     

    code algo:

    1) while(PORT A = = oxff);

    2) if (PINA.0 = = 0)   output user1

     elseif (PINA.1 = = 0)   output user2

     elseif (PINA.2 = = 0)   output user3

     elseif (PINA.3 = = 0)   output user4

     elseif (PINA.4 = = 0)   output user5

     elseif (PINA.5 = = 0)   output user6

     elseif (PINA.6 = = 0)   output user7

     elseif (PINA.7 = = 0)   output user8

    else goto step(1);

    3) goto step 1;
