need assembly sample code 89c51 display

hi
i want to make display board using assembly code using 89c51 pls any one give me sample code for this circuit

hi

can you post where you are having problem in your code?

also why are both serial inputs of 74164 tied together?

sir i need asm file this is written in c

; P2 DISPLAY DATA 8 BIT
; P3.0 SERIAL DATA
; P3.1 SHIFT CLK
; P3.2 STORE CLK
; P3.3 M CLEAR

; here 595 sh reg are use and delay set according to your hw xtal

DIS_BUS EQU P2

DATA_BIT BIT P3.0
CLK BIT P3.2
STCLK BIT P3.1
RESET BIT P3.3
