    Hello…

    i need to display the keypressed number on lcd and multiplexed 7seg at the same time..

    because seven segment needs to be in continuous loop for multiplexing

    Is there a way..

    THANK YOU

    YES, you can use 7 segment drivers like MAX6954,HEF4543B,MAX7219CNG

    generate an interrupt when key is pressed

    otherwise just remain in continue loop to display number

    or else use timer interrupt to refresh 7segment displays at regular intervals
