How to interface both lcd and multiplexed seven segment display with a single arduino

[Bhuvan]

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

[Ashutosh Bhatt]

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
