OK i want to know if i can use binary numbers in a code

Hi mikeduff76,

I think you are asking if you can write binary literals into your C code. The answer is no, the C language does not have a way of writing binary literals, however you can write hex literals by prefixing them with 0x. Once you get used to it, its pretty easy to convert between the hex and binary representations of a number.

Some compilers may let you get away with using this format:

uint8_t test = 0b01001001;

I've gotten errors using this with "cl.exe" but not with "gcc" in MinGW. I have not tested it with "avr-gcc".

The 0b prefix works fine. I have used it before. Sometimes it makes the logic a bit easier to "see".
