Bad Servos??

Half-Lucas

I was coding a simple program, which makes the servos start, run for 3 seconds, then stop.
However, the servos didn't stop. Apparently the program is looping itself forever...

This is the program:

' {$STAMP BS2}
' {$PBASIC 2.5}

DEBUG "program running"

counter VAR Word

FREQOUT 4, 20, 3000
FOR counter = 1 TO 122

PULSOUT 12, 850
PULSOUT 13, 650
PAUSE 20
NEXT

PAUSE 2000

END


why does the program loop itself, if there is an END and if the Loop is restricted???

Do you get the 'program running' message multiple times? If so, this is a very common occurence when you 'brown-out' the BS2's power by putting too great a load on the Vdd line with something like a servo.

So I'd look at the batteries you're using.

Hmmm... good thought, but all I'm using except for the servos is the piezospeaker. I don't know how I can "Brown out " the chip like that...

YES that was the problem! I replaced the battery! Thank you for your help
