i want to config camera

[ayoub]

hi
i have a web camera for pc and i lost cd configuration so i want to how can i define a cam ?
please
thank

Show us the code you have written in assembler and someone may be able to help you. It sounds like you need to track down the company that made the camera and see if you can get a copy of the installation/configuration files that you need.

I have a web camera it name ZNITH and i use some to read and write from serial port to read how the array write from camera but it not me it give a some eurror from serial setting "undefined variable"
this is code:

thank for help
but were is code to write the first or second to difine variable , i have a windows 95

[jj2007]

but were is code to write the first or second to difine variable , i have a windows 95

You won't get help if your requests are so vague.

[ayoub]

so
me idea i want to read the array from camera and put this array in opengl to play the camera

[jj2007]

Where is your "code to write the first or second to difine variable"? And what does that sentence mean?

[ayoub]

Did you add the first "Windows.inc, line 12205" or "the second Use this version" or both code to run in win 95
thank

[jj2007]

Only the second version works. I don't have Windows 95 to test it.

[ayoub]

thank you for help

i have a question i want to build a hex file , can i do that by masm

[jj2007]

Yes.

[ayoub]

how can i do a hex file or other file like binaire

[jj2007]

1. define your task
2. read the manuals (\masm32\help)
3. start coding
4. in case you have problems, post your code here and ask intelligent questions

[ayoub]

I want a method of producing hex file like a namefile.hex
i want the code or way to build hex file
