    Hi there. I am working on a digital elevator using a microcontroller 89C51. ht elift starts from the ground floor. the lift is supposed to travel upto 'n' floors. Also while travelling it should respond when all buttons are pressed simulatneously. when all buttons are pushed it should go floor-wise and stop on the desired floors. also priority should be given to up/down direction. if the lift is trvelling up then it should continue to travel up regardless of whether the down button is pressed or not and vice versa. the output of the push button should be displayed on a 3-1/2 segment LCD display.

    can u help me out with the block diagram algorithm for the same?
