Hi,
I came back again

Thanks for explaining me how to simulate the circuit but i have to write the program. I wish i could write in C, unfortunately i have to write it in asm, even in tasm. So i dont have much time and i cant find sources. You helped me a lot but please if you can show me how to finish this, i will be very grateful.
I dont know how to write those functions for key_pressed situation.
And another question, should i use a pic to get the data from parallel port and from push buttons and then control the 7seg and dc motor? or should the data from parallel port control the dc motor and the 7seg ( but then how can i include push buttons )?

; cursor function
cursor macro r,c

mov bh,00
mov ah,02
mov dh,r
mov dl,c
int 10h

endm

; display function
display macro str
mov ah,09h
mov dx,offset str
int 21h
endm

.stack 64
.data
l1 db ' Welcome ','$'
l2 db ' Press f to rotate clockwise ','$'
l3 db ' Press r to rotate counter-clockwise ','$'
l4 db ' You may adjust the speed by speed adjust buttons ','$'
l5 db ' You can see the motor speed on the 7-seg ','$'
l6 db ' Press q to quit the program ','$'

delayer dw 33147
hu dw 0
ku dw 0

7segport db ?

motorport2 db ?

btnDownPort db ?
