Hi,
the frequency is not stable.



it would owe emetter a sound of height 100 and duration 50mS. In reality, if I program here the code under,
a sound first lower part sends forth me and then one tall.
Practically 2 sounds of which one don't have anything to do with it nothing.


LOOP:
Breaks 1000
SOUND PORTB.0,[100,50]
GOTH LOOP


best regards and THX
