Help pls..emergency abt pic program

[[email protected]]

hello everyone
This is Monicca doing my final yr of engnr.I have done my project in
embedded sys with pic micocontroller.I downloaded the program from net
n i dnt understand anything.I have my review on thursday.So pls can
anyone suggest a website for the better understandin of the
program..pls I really need help..
Now this is the program..
#include <pic.h>
#include <stdio.h>
#include <delay10.c>

static void interrupt IntRoutine();
void Send();
short int Flg=0;
int Cnt = 0,Oflow=0,Mytime=0,Adval,Hbc,Hbr;
char St1[4],St2[4],St4[3];


void main()
{

TRISB = 0x00;

TMR1L = 0xaf;
TMR1H = 0x3c;

for(;

if(Oflow)
{

Mytime++;
}


ADCON0 = 0x81;
DelayUs(50);
ADGO = 1;
while(ADGO) continue;

if(Adval < 100 && Flg == 0)
{
Hbc++;
Flg = 1;
}

if(Adval > 100 && Flg == 1)
{
Flg = 0;
}

if(Mytime > 3 && Mytime < 60) RD0 = 0;

if(Mytime >= 60)
{
Mytime = 0;

if(Ebc > 15)
{

}

}

sprintf(St1,"%3d",Ebc);

}

}





static void interrupt IntRoutine()

Tsk, tsk...are you trolling or genuinely clueless? Engineering is a
profession, you know...not just memorizing dead facts. I suggest you
withdraw from Engineering and take up some profession such as staffing a
bureaucracy somewhere, where you're never required to know anything or
come up with a practical answer on time. Your entire coursework was
designed to impart to you the understanding you needed to complete the
course, had you done the work.

Which Engineering school are you attending? I'd like to complain to
them that they are not teaching their students any ethics, along with
the technical side of the course work. There's an old saying that
"technical competence is a dime-a-dozen" but someone who can manage
technical projects and produce results on-time will never lack for work.

Is it me, or does anyone else notice the rise in "women" in engineering?

How do you know the OP is a woman?

What I think we should be noticing is a much larger proportion of people
being pushed into further education. I don't see any reason for a
proportional rise in aptitude so I would not be surprised to find more are
floundering.
