0v7670 camera interfacing with stc 8051.using assembly language.i've search the for the coding everywhere but i didn't found it.

The 8051 has too little memory to do anything useful with a 0v7670.
What do you want to do ?
Why use an 8051 and why use assembly language ?

To capture the picture when pir sensor detects movement,and display the picture on pc.
My lecture wants the camera to connect to 8051.at first my lecture wants it in assembly.then he said c is also fine.

I tracked down a OV7670 data sheet.
The OV7670 puts out the whole frame in a single burst.
This means you should store a whole frame, before sending it to a PC.

A frame is around 307200 bytes.

No micro can store that much, so I believe Arduino projects send one line
from successive frames to build up a single frame.
This is only any use for still photos and takes a long time.


A standard 8051 has 128 bytes, so could only store part of a single line.
Building up a frame this way will be very slow,
and need customised software on the PC.


"is it possible? "

Possible? .. yes
Worth doing .. no.

One option is to use a ov7670 module with built in buffer.

Perhaps your lecturer can give you hint as to how to do it ?

No.he didn't give any😭. he ask me to find the code,he knew i don't have the skill to code.so i just have to find the code and paste it into mcu.right now im trying connected the camera to arduino r3

You will not find any code for an 8051 as no one would use it !
Making it work is a big challenge for anyone.

You might find code for one of the 8051 variants with more memory
but that's not really using an 8051.
Getting experience using the camera with an Arduino is a good idea,

We've already given up.right now im trying the camera at arduino.wish me luck☺.
1 more question. Is it possible to interface a fingerprint scanner to 8051?
thank you for answering all of my question.

" Is it possible to interface a fingerprint scanner to 8051?"
I think so.
Some fingerprint readers hold all the fingerprint data in memory
and only need a serial connection to work.

One problem, is that all the software I have seen is for Arduinos.
To use with an 8051 might mean writing a lot of your own code and it seems
to be hard to get good programming information for some types of reader.

Be sure that you can get all the programming information before
you buy a reader.
