    lol right...im just asking about who knows about c programing on hardware...its not like i didnt write my own programme out...i just need help on it since my lecturer is not helping cause he isnt alowed too its procedure..he says by all means seek help outside its part of research...so not to wory about #9 i mean this is considered reserach i haf been looking at google and found nothing...this is the best place i find for soemone to help me understand c programme more.... im not breaking rules am i.I wouldnt seek for more knowledge of c if my lecturer is good enough to help me...we haf to find out how to do it without his guide he deals only with the hardware....but i find c very compicated i hope u ppl understand.

    I Only got as few questions to ask...thats all...i do not expect ppl doing it for me...so dont get me wrong

    So ask your questions here then.
    STL Util a small headers-only library with various utility functions. Mainly for fun but feedback is welcome.

    Your lecturer should provide with at least some information to get you started.

    When I did microprocessing most of the programs I started with involved using *assembly* language, perhaps that is where you should start.

    Microprocessing, looks scary to begin with, all those codes in binary or hex and masking of bits, nibbles, etc, but it's actually pretty straight forward.

    The information you need to send to your output devices (port A/B) should be computer dependant. You need to obtain the output addresses from your lecturer.

    So in short- ask your lecturer
