#45263 - RE: ADuC812 and ADC problem
Responding to: ???'s previous message
hi everyone.
Still not working;
I’m still confused how to sync. Between the data for ADC and take these data and do DAC
AS 8bit only
The code that I modified is as follow:
;--------------------------------------

ORG 00000H ; Execution Starts Here

; set ADCCON1 register to enable Normal
; A/D conversion mode
MOV 0EFH,#07CH
; set ADCCON register for 8 bit mode
; with DAC1 power-off
MOV 0FDH,#0FDH

;------------------------------------
; MAIN
LOOP1:
; set ADCCON2 register for Continuous
; Conversions at channel 0

MOV 0D8H,#020H
; Store the result of Con.
; from ADCDATAH into R3 MOV R3,0DAH
; Store the result of Con.
; from ADCDATAL into R2
MOV R2,0D9H

MOV A,R3
ADD A,R2
MOV R4,A
; Move the data into DAC0L
MOV 0F9H,R4
CALL DELAY ; Call delay
JMP LOOP1
;
;_____________________________________

; Subroutines

DELAY: ; delay 100ms

MOV R7,#200 ; 200 * 500us = 100ms
DLY1: MOV R6,#229 ; 229 * 2.17us = 500us
DJNZ R6,$ ; sit here for 500us
DJNZ R7,DLY1 ; repeat 200 times (100ms delay)
RET

;______________________________________
End ; End Of Program
