@ Define GPIO pins for each segment of the 7-segment display
.EQU SEG_A, 0   @ Segment A connected to GP0
.EQU SEG_B, 1   @ Segment B connected to GP1
.EQU SEG_C, 2   @ Segment C connected to GP2
.EQU SEG_D, 3   @ Segment D connected to GP3
.EQU SEG_E, 4   @ Segment E connected to GP4
.EQU SEG_F, 5   @ Segment F connected to GP5

main:
    @ Initialize GPIO pins for each segment
    MOV R0, #SEG_A

loop:
    @ Display each number 0-9
    @ You need to define the logic to light up the appropriate segments for each number
    @ Example for displaying '0' (light up A, B, C, D, E, F and turn off G)
    MOV R0, #SEG_A
    MOV R1, #1
    BL link_gpio_put
    @ Repeat for B, C, D, E, F with R1 as #1 and for G with R1 as #0

    @ Delay

    BL sleep_ms

    @ Continue for numbers 1-9 with appropriate segment control
    @ After displaying '9', loop back to '0'

    B loop  @ Repeat indefinitely
