Hi, I want to to copy the data of and external ROM adress to an external RAM adress,
my try :
CLR A
MOV DPTR, #8000H ; 8000H is the ROM Adress
MOVC A, @A+DPTR; A gets DPTR's data
MOV DPTR, #6000H ; 6000H is the RAM Adress
MOVX @DPTR, A
is this program correct? if yes is it the only method?
Hi, I have a question about 8051
I have an instruction which at adress 0020H and codded as 80F0H
what would be the value of PC?
i don't understand how can i decode it
I am trying to display 1 through 9 while rotating on win8051 what am i missing here:
; Initialize number to display
MOV R1, #0
; Main Loop
LOOP:
; Display R1 on the 7-Segment
CALL GETDIGIT
CALL DISPLAY
; Wait one second
CALL DELAY
; Increment R1
CALL INCREASE
; Repeat the Loop
JMP LOOP
; Delay...
So we've been instructed to write an assembly language program to display numbers 0-9 on a common anode 7 Segment Display and simulate it using the Proteus Software. (8051 microcontroller) (And 0-F as well)
I'm a complete beginner in this field and was hoping that I'd get some help here from...
I was tasked with creating a certain 8051 microcontroller project by my professor and I am keen to build the project all by myself, however, in order to carry out the given assignment, I may need some expert guidance. The project description is provided in below paragraph.
The microcontroller...
I currently working on a MCS-51 based project and I tried to burn hex file into my microcontroller. The microcontrollers I used are AT89S51 and STC89C51RC. I tried to use ProgISP and AVRDUDESS to burn hex file into the chips but both came up errors.
When I use ProgISP to load up hex file, this...
