HELLO

I WANT TO SIMULATE TWO INPUT SIGNAL (SINUSOIDALE) ALTERNATIF VOLTAGE

SO WHEN I SIMULTE THE FIRST AND I TAKE SWATCH(0.000001)
I RECEIVE THE JUST VALUE BUT WHEN I ADD THE NEXT SIGNAL WITH THE SAME SWATCH
LIKE THIS

VOID SIGNAL MAIN()
{ MONO();
TRI();
SWATCH(0.000001)
}

I RECEIVE THE GOOD VALUE OF MONO AND NO JUST VALUE FOR TRI
AND WHEN I TAKE SWATCH(0.005) I RECEIVE THE JUST VALUE

IT'S FOR THIS REASON I WANT KNOW HOW CAN I FIXED EXACTLY THE SWATCH TIME THAT MEANS I DELAY BY WICH NUMBER OF SECOND TO OBTAIN THE GOOD VALUE OF TWO SIGNAL

first: please turn off your CAPS lock.
second: please define "JUST VALUE" vs. "NOT JUST VALUE".

ok
i am sorry for caps look

my question is

what is the difference when i write swatch(0.000001)
and swatch(0.005)

and what is the impact for the target program
thank you

swatch is a delay function, so
swatch(0.005) waits for 5 milliseconds while
swatch(0.000001) waits for 1 microsecond.

THANK YOU

YES I AGREE WITH YOU BUT WHEN I TAKE SWATCH(0.005) to delay 5ms so why i need take swatch

and what's the probleme when i not write it

not using it will not delay whatever it is that you are doing - for example, it will not change a signal because the generating function is waiting. what you are asking is very specific to what you are doing. sometimes not waiting will be a problem, some other time not.

WHEN I MUST USE SIGNAL FUNCTION AND WHEN I USE USER FUNCTION?

WHAT IS THE DIFFERENCE BETWEEN TWATCH(100) AND SWATCH(0.000005) ? FCPU=20MHZ

what means twatch (clock) it's wait for 1s or wait for 20000000 states (fcpu=20MHZ)

thank you

You like to shout. Please don't, it affects our hearing...

Have you looked at all the documentation Keil has published about how to write signal functions, and the available statements?

hello
yes i have look all keil documents
but i don't find what i want

can you answer me for my question posted to the forum without documents
thank you

If you have looked at "all" Keil documents, does that mean that you have looked at:
http://www.keil.com/support/man/docs/uv3/uv3_debug_functions.htm
and still not found the information you want?

THANK YOU FOR YOUR REPLY

BUT I M SORRY ?IT'S NOT MY QUESTION

I DONT KNOW WHEN I NEED TO USE TWATCH AND WHEN I MUST USE swatch ?

WHAT IS THE DIFFRENCE between twatch(100) and
swatch(0.000005) WITH CLOCK=20MHZ

THANKYOU

Yes, your screaming monster, it does answer your question if you just care to spend a couple of seconds to read.

swatch says:
"The swatch debugger function is used in a debugger signal function to delay until the specified number of seconds has elapsed."

twatch says:
"The twatch debugger function is used in a debugger signal function to delay until the specified number of CPU states has elapsed."

Now, between your shouts, try to ponder the following: What happens if you specify your timing in states or in seconds, if you have a processor that changes its clock speed (for example to reduce the power consumption from a battery, while it is waiting for something to do)?

Would it matter then if you count time, or count number of CPU cycles until generating the next external event?

thank you

i want know that if i use cycle cpu time or time in second is the same method

i work with clock=20MHZ

so 1 states=50ns

if i take twatwh(100)
100 cyles time -->100*50ns=5000ns

5000ns=0.000005000s

so if i write twatch(100)is the same when i write swatch(0.000005000) ?

dear ABDELAZIZ, that is not the point: the point is that one function is CPU speed dependent, and the other not. in other words - as long as you do not change the operating frequency of your processor the interchanging these function will make not difference. once you do, and want to wait for the same amount of time, you must either use 'swatch' or change the argument for 'twatch'.

shall we that bet his next message will be with CAPS lock on? :-)

please can you tell me if my last question you are agree or not agree for my reflexion

i work with the clock=20MHZ always

thanks
