Binary Clock

Hello, Was wondering if anybody could help. I'm trying to code a binary clock for a project at school and I'm hitting a wall with the time delay code needed. My setup is 11 LED lights (6 for minutes, 4 four hours, one for am/pm hooked up to an 8051 microcontroller) I can use C or Assembly, but I've been working more with C lately and am fairly knowledgeable of it. Also any ideas for the input code to set the time will be great, haven't really had much time to mess with that aspect yet. Thanks in advanced

    Well, to give you an idea of what I am thinking. There are 16 colors in Borland Turbo C 2.01 compiler. So you could use that. As far as hooking it up to your 8051 microcontroller, you could probably do that also in assembly. Borland Turbo C 2.01 allows you to insert assembly code where speed or electronics stuffs is necessary. I am not sure how it is done. However, I think you will have fun with it. Just google, "Borland Turbo C 2.01" it is free. If you need a time delay code, try this:

    int main() { int delay, count;

    delay = 12000; DELAYloop:; if (delay > 1) { delay--; }

    return 0; }

    Anyways, that is the delay. C is so fast that you need like maybe delay to be hundreds of thousands or even million to pause a second.

    If you do use a longer delay, you may need to change the int to a long

    I forgot to add a goto DELAYloop; at the end of delay--;

    I had a lot of help learning along the way and I am still learning so do not think you are cheating if you ask questions.

    Thank you so much, this has been more immersive that I thought it would be.

    Jesus Christ!hehe You are welcome. I am grateful to your replies. I know assembly language can be tedious and tough especially having to know all the registers; however it gives exact control over your microcontroller. C does "not" have that specific machine interaction. C is only a superficial language. In the brief times that I have programmed C and assembly language, I notice that about each.
