pulsin again!anyone plz help!

if tmp >= 500 then
Will never be as tmp is BYTE size

Very good, a byte can count from 0 to 255.

That could give unpredictable results (except for the gurus that can most likely figure exactly how it will go screwy ); it may work, it may not.

@ Demon, I do not at all to be a guru who could figure out how it will go screwy, I am fairly certain IRBUTTON is ALWAYS = 0 after his for loop. Since there is NO way to cram a number bigger then %11111111,$FF,255 in a byte, it will always do the else setting all 11 bits to zero.

So I would certainly question the OP's statement that it works, I think it prolly does in fact receive the signal, and detect the header. but I think from there it will fail as soon as it is tested for specific button presses.

We shall wait and see

without to check your code i think you should consider the frames (codes) of the ir Sony protocol... because Sony remotes all appear to repeat each frame a minimum of 3 times...and also i think you toggle the led by pressing too long time the button on the remote ..... add some some long pause for test

@cncmachineguy thanx a lot for pointing me the problem.i ve been a fool n i admit... the toggle function works fine... thanx v much again your approach has been dead on...g8 advice for beginners!!
@demon u r right as well.the code is working for all the buttons of my remote(unexpected results)... not for just button <9 .problem wid temp most probably... i'll declare it a WORD n c how it goes...!

@bogden thanks for your input as well. i have put a delay of 100...

my final code it is toggling on button 6 of your sony remote.n the good thing is no interrupts or timers simple code

TrisB = %00000100 
Start:

Pulsin irin,0,header 
if header < 1000 or header > 1350 then goto Start
 
check: 
for i =0 to 11
pulsin irin,0,tmp 
if tmp >= 500 then
Body.0[i]=1 'Sony Logic 1 is 120
else
Body.0[i]=0 ' Sony Logic 0 is 60
endif
next
IRBUTTON = Body & %01111111
 
if IRBUTTON=5  then
loop:
toggle Sonyled
 
endif
pause 100
goto start

copy/paste n njoy love PBP!!!!

Insignificant, but I would change this:

if IRBUTTON=5  then
loop:
toggle Sonyled
 
endif

To this:

if IRBUTTON=5  then toggle Sonyled
