Which board? What kinds of tests? What is your application?

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!

There is no special program called demo.s19. The s19 extension
simply indicates that this is a binary format file. "demo"
is simply an abbreviation of "demonstration".
Unless you can post actual requirements you aren't going
to get any help. Also, if this is a class assignment,
be aware that your professor is reading this.

Re: help - BobG...@aol.com - Sep 8 11:21:17 2006
The programs for this board can be downloaded from the Technological Arts site in
Toronto... the demo.asm file is only a couple of lines of assembler... assembler is
included in zip file...

Re: help - Tony Stram - Oct 4 9:36:12 2006
Charles,
=20=20=20
If you are using the Imagecraft compiler, there will be a file called vec=
tors.c. In this file you would extern your interrupt handler like this:
=20=20=20
extern void TimerOverflow(void);
=20=20=20
The vectors.c file then uses a pragma to set the address:
=20=20=20
#pragma abs_address: 0xffd6
=20=20=20
Next comes the vector table:
=20=20=20
void (*interrupt_vectors[])(void) =3D=20
{
DUMMY_ENTRY, /* SCI */
=20=20=20
Dummy entries would fill the table. When you get to where your timer over=
flow handle would be, you replace DUMMY_ENTRY with TimerOverflow:
=20=20=20
TimerOverflow, /* TOC1 */
=20=20=20
You will even find the label _start that is defined in crt11.s:
=20=20=20
_start /* RESET */
};
=20=20=20
Then you finish it off with:
=20=20=20
#pragma end_abs_address
=20=20=20
If you are using another C compiler, then you would have to find out how =
that compiler handles absolute address and assign the vector table to that =
range of addresses. Though the pragmas are not portable, the reset of the c=
ode is. If you are using the Imagecraft compiler you will have to use one m=
ore pragma:
=20=20=20
#pragma interrupt_handler TimerOverflow;
=20=20=20
This tells the compiler to use the rti instruction instead of rts. If you=
are using a different compiler, you will have to find out how to tell the =
compiler to use rti instead of rts for interrupts.
=20=20=20
Hope this helps,

Re: help - charles paul - Oct 5 6:19:15 2006
thanks tony,but still there is one problem...
i will attach my program with this e mail..just tell me where i am wrong...
i have given a printf statement in subroutine just to check whether its runnin or not ...my o/p for this program is 0 E clock cycle(.c file opens with notepad)
as u must have already guessed tis is program for period measurement....
kindly tell me where i am wrong...

Charles,
Not sure if it is yahoo or yahoogroups, but there is no attachment to the=
email. I will take a look at your code and help you as best as I can. Most=
of the coding experience I have is geared for hobby robotics. BTW, which C=
compiler are you using? This will help figuring out what the compiler is e=
xpecting when dealing with interrupts.
