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 reset if it hung
regards

Can you post your code and schematic?
About your other process... any of those use interrupts?
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
Code:define osc 20
Include "modedefs.bas"
TRISA = %00000000
gdata var byte[21]
x var byte
ok var bit
main:
x = 0
gps:
if ok == 0 then
serin2 portb.0 , 188 ,[wait("GPS") , str gdata\20]
toggle portb.1
dtmfout porta.3 ,100 ,100,[ 10 , 0 , 10 ]
for x = 0 to 20
pause 10
if gdata[x] = "." then
gdata[x] = 12
endif
dtmfout porta.3 ,100,100,[ gdata[x] ]
next x
ok = 1
endif
serin2 portb.0 , 188 ,[wait("SD") , str gdata\4]
ok = 0
toggle portb.2
dtmfout porta.3 ,100,100,[ 10 , 1 , 10 ]
pause 1
for x = 0 to 4
pause 10
if gdata[x] = "." then
gdata[x] = 12
endif
dtmfout porta.3 ,100,100,[ gdata[x] ]
next x
pause 50
goto main
Are you positive it is not hung waiting on a serial input?
Don't know if it's a cut/paste problem or what...Code:define osc 20
Read the manual and what it specifically says about DEFINE's... And ENDing a program (or STOPping it)
As far as an 'automatic reset', look in the datasheet under WATCHDOG.
i am positiveQuote:

:rolleyes:
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 me the problem is not in " defines "
sorry for mistake
Then go back and look at post 5, Skimask is as subtle as a nuke, he is telling you a lot there.Quote:

and other thing (define) erorr may not let pic work stable or work at all
and my circuit hung after 10 min of good execution time :) (it looped fine for 10 min)
when i used WDT it work fine .
you know the problem of pic basic pro is most of functions work at background
so you will be far from (hardware imagination execution) to track erorrs like this one
Very likely the problem is the time taken to dtmfout between the two serin command. If the for/next loop takes just longer than allowed you miss tx bytes and your system is out of syncronism. (Remember you have a wait comand)
Remove
And dtmfout after the second serin command, to be sure to avoid loosing tx bytesCode:dtmfout porta.3 ,100 ,100,[ 10 , 0 , 10 ]
for x = 0 to 20
pause 10
if gdata[x] = "." then
gdata[x] = 12
endif
dtmfout porta.3 ,100,100,[ gdata[x] ]
next x
Al.
my serial data source is repeat it self continuously
when the first package arrive the the buffer will be load
and then first (FOR) loop will execute meen while there is serail data looses
after first (FOR LOOP)
the second serial in command will wait for other Sync WORD "SD"
because serial source repeat all data packages continuously (if because of loop
i miss the first appearing of "SD" at the end i'll catch it no matter what )
it works gooood
all data transmit ok and tone appear OK for 9 to 10 min of operation and the two FOR LOOP update continuously
--------------------------------------------------------
the hung is apear on tone sound
normaly DTMFOUT sounds apear like this
[toot -- teet -- tut -- tat -- tet - toot --tiit - toot ----> for 10 minuets ]
and then it become sounds like this after 10 min
[teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet] -------> till reset :)
I don't want t o be pushy, <b>but </b>did you fix these things? Which is to say, Did you put your DEFINES IN UPPERCASE? Did you put END at your programs END?Quote:

Step1.Fix the problems you know about first then hunt for more.
<br>
So how about disabling the analog stuff, ADCON, CCP . . . since you are using PortA.3
no idon't think it's PS failing problemQuote:

well idon't know what is ( definitive ) the problem he umbrella the all issue in weird way ( chick datasheet and chick manual and all this stuff )Quote:

also show me haw END program as you mention
How about the PORTA.3 problem Joe mentioned?
This will help

thanks dave i'll work on that ;) and tell you what is outcomeQuote:

Sorry about my English, I am American you know.:D
Go into the data sheet, I know it's painful, but go in there anyway . . . Look to see what state port A initializes in when it is reset, you will probably discover it defaults to <b>Analog</b> operation, since you want Digital, <b> YOU </b> need to tell it<b><font color=red> how to be digital.</font color></b> Lots of registers to set, If you want simple then use old grandpaw chip like 16F84, or 16F628A, only CMCON to worry about. If you want lots of bells and whistles then you have to learn how to play them.Quote:

i didn't said any thing about your English or about you generallyQuote:

for ppl like me :o
well i may a dumb person but i wrote my code to be End lessQuote:

well i have all those pic's you wroteQuote:

it will work in rough and dirty environment so there is other things must be worried about so the design have more dimension than you imagine
although am not from there but i bet you i worte more code lines than youQuote:

and stop been futile person
Yep, I will bet you have too, I didn't know this was a competition, I thought I was trying to help you. My apologies, it won't happen again.Quote:
