Hey,

I am working on getting a camera that works through the serial port working on a processor of some kind (probably an ARM). But now I am working on getting it to work with my PC. I am writing in c# and can get an array on bytes describing the image.

It is an 80x60 image using 16 bit colour. So overall it is 9600 bytes (80*60*(16/8)). One pixel may look like 0x0e, 0xaa. This equals 3754 in a decimal number system.
I need to get the Red, Green and Blue components from this number and i have no idea how.

Anyone got any ideas?

[edit] Just corrected some typos

Thanks,,,

You want to look for how to extract nibbles from a byte, which is quite easy if you know your bitwise operators!
