thank you joe for attention
anyway just to make something clear :)

normaly i use programmer software to set all (define) like HS , MCLR_OFF , LVP ...etc

and other thing (define) erorr may...

looool don't get my ( :rolleyes: ) in wrong way bro
what i ment was (your suggestion will be consider) nothing more
i can't be rude to any one try to help me
thank any way WDT work fine with...

:rolleyes:

i am positive
hung appear on audio (tone become wierd) and leds stop toggling

hello no (interrupts)
this is my code
no schematic release yet still prototypal :)
but u can figer it out from code

pin b.0 is serail in
pin a.3 is audio out

hello am using pic16f819

my problem is i use DTMFOUT function inside (for) loop this causes some times process hung after almost 9 or 10 min working time
is there any why to make pic self...

am using 16f877a but guess what i found the problem :)
