8051+ADC0809

sample code and circuit
;THIS DEMO PROGRAM READS DATA FROM ADC TO MCU AND
; OUTPUT WILL BE SHOWN IN P1 AS BINARY VALUE
;P0.0 = A0 P0.1 = A1 P0.2 = A2
;P3.2 = EOC
;P3.3 = START
;P3.6 = ALE
;P3.7 = OE
;DATA = PORT 2
MOV P0,#00H
MOV P1,#0FFH
MOV P2,#00H
MOV P3,#04H.............................

if this code really works ?
because i had experience interfacing 8051 and ADC before .
We nid to wait for the ADC to convert analog input to hex before it transfer to 8051
8051 is usually much faster than ADC . hence , we nid to check the busy flag of ADc while it was converting data

nice TPS

create drivers or say API kind of subroutines so people can easy use them
