Copying a binary image file to the framebuffer

lbuccola · 07-14-2010, 09:33 AM

I'm running Linux version 2.6.33.4 on an ARM9 and can successfully copy directly into the framebuffer using the command:

Code:

cat /usr/myfile.bin >/dev/fb0

I converted myfile.bin from a 640 x 480 x 24 bmp.

What I'd like to do is to have the ability to dump .bin image files directly into the framebuffer from a C program without shelling out to a cat command.

What would you suggest is the best way to do this?

Thanks

Enter

fopen /dev/fb0

into Google and read what in my case is the very first match.

Hi,

Can you teach me how to convert the bmp file to bin file? Thanks.

What is the 'bin' file ? I.e. which particular format do you expect it to have ?

If you need to convert files from one image format to another, start from http://www.imagemagick.org/script/index.php .
