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
process hung problem + self reset

Can you post your code and schematic?
About your other process... any of those use interrupts?
Steve
It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

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?
Dave
Always wear safety glasses while programming.

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 positiveOriginally Posted by mackrackit
hung appear on audio (tone become wierd) and leds stop toggling

Ok, but that so-called code you posted has 3 definitive problems in it.
You get to figure them out now...Okzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

looool don't get my (
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.looool don't get my (

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 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

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?
I think I would rather notWait until you see me in my 'Officer Jim Dangle' costume this weekend...

I am wondering if it is not a power supply problem. After a few minutes the the PS starts to fail/drop voltage.
Is the speaker direct connect to the PIC?
Dave

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 problem
speaker connected though CAP

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 )
if you see any error need to fix . please give me some guidance with few code lines
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 thatand tell you what is outcome

last word in your program on the last line should be . . .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 )

this I believe is a compiler directive, tells the compiler to end your code there. There is at least one exception to this rule, but not here and not now.Code:<b><h2>END</h2></b>

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.

i didn't said any thing about your English or about you generally
---------------------------------------------------
Sorry about my English, I am American you know.
but ...anyway
for ppl like me
well i may a dumb person but i wrote my code to be End less
therefor my last line is
did you notice that or.. or... you never saw the code in my first postCode:<b><h2>GOTO main</h2></b>
|
well i have all those pic's you wrote
but i don't want this circuit to work in my lab only
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 you
wither on asm , C18 , C32 , css , pic basic pro
take this advice
work more ....
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.
