This code initializes GPIO pins for controlling a 7-segment display and defines functions to display numbers on the display.

The function SEG_Init initializes the GPIO pins for the 7-segment display segments and data lines.

The function Dsg_Display takes a number as input and displays the corresponding pattern on the 7-segment display.

The function Num_Show takes an array of numbers and displays each number on a separate digit of the 7-segment display sequentially with a delay between each display.
