| PIC18F2523 watchdog issues |
 Posted: Sun Nov 09, 2014 4:09 am |

|
I'm having some problems with the watchdog in my program. This is the first time I want to use a watchdog. Occasionally my controller stalls due to voltage spikes caused by switching an inductive load. I'm trying to solve it in the hardware but I want an additional safety back up in the form of a watchdog.
The watchdog interval can be set between 4ms and 131 seconds. The problem I face is that my uc resets almost immediately no matter what I set as WDT time.
First the necessary information:
Compiler version: 5.018
Controller: 18F2523
External crystal of 20MHz
As far as I understand the WDT it works as following. I have set the WDT to #FUSES WDT32768 which means a that it should reset after about 130 seconds.
In my program I need to restart the WDT (restart_wdt(); ) to prevent it from resetting my controller.
So if I restart the WDT within the 130 seconds it should not reboot my uc, correct?
I have listed the main routine of my program and skipped all the functions otherwise it becomes quite a piece of code. If these are necessary to list just let me know.
It performs the INIT() routine and enters the "Waarden" case. It shows the data for about a second and restarts.
My questions:
Is my understanding of the watchdog correct?
Why does my controller resets within a few seconds after it has started?

hmm....
in your fuses as posted
#FUSES NOWDT //No Watch Dog Timer
needs to be
#FUSES WDT to 'enable' the WDT.
and...
I think that before you enable 'global interrupts' you should do all 'setup code'. Others will know for sure but the PIC might see an interrupt before the rest of the setup is complete, go to the ISR, do 'stuff' and not perform right as some 'setup' variables were not initialized with your default values.
Last thing I do before main() is to enable global interrupts so I've never seen it but it sounds like it could happen.

No, he is enabling the watchdog in software.
On these chips, if disabled in the fuses it can be enabled by the SWDTEN bit (which WDT_ON sets).
Lots of potential problems, and the actual 'killer' at the bottom.
One potential problem is clearing the watchdog after enabling it.
If the watchdog has already triggered, this will result in a restart.
The watchdog needs to be cleared before enabling it.....
Other thing is don't assume the timings will be accurate. On these chips it "isn't bad" (controlled by the internal RC oscillator), but on most chips the 'nominal' time can vary between about 45% and 150%. Ouch.
Old comment applies 'ADC_CLOCK_INTERNAL', is _not_ recommended for use above 1MHz CPU clock rate. Read the data sheet.
Then the 'eeprom' code has me worried. Have you calculated just how quickly the EEPROM (or external EEPROM) can be killed by saving at regular intervals?. Not a good approach. Also what happens while the code is 'stuck' in this interrupt?.
Then the comment applies that was given in another thread. This is _not_ how to use a watchdog. If the chip is glitching, then look at a brownout reset instead. If using a watchdog, the restart_wdt, want to be setup so it can _only_ be reached, if the code is actually running properly. Testing that everything is working, and laid out so it cannot be reached if the code is executing something like a drunkard's walk (which is likely to happen with a brownout failure).
Then you have huge delays scattered around. A 50mSec delay, inside a 200* loop for example. Now this would (of course) give a watchdog restart with any divider less than 4096. Unfortunately, I know that the compiler will not actually program a WDT divider higher than WDT512 for this chip....
Load the LST file, and see what the watchdog timing is set to. |

Thanks for your answer. I was under the assumption that "SETUP_WDT(WDT_ON)" at the begin of the main was sufficient.
Got that out of the following link: http://www.ccsinfo.com/forum/viewtopic.php?t=24055&view=previous
Nevertheless I tried is as you described but it makes no difference.
I don't understand your comments about the global interrupts. All setup/initialization is done before I enable the global interrupt. Or do I miss something here? |

Just missed your answer Ttelmah. My previous comment has more or less be answered by your comment.
About the timings. For my application the timing is not precise. The controller may hang for a few seconds before it is rebooted. But if the WDT can't be higher as 512 then I will have a problem. That would result in a time of ~2 seconds under ideal conditions. My delays are longer...
If I open the list file I find the following:
| Code: |

.................... //#device ICD=TRUE
.................... #device adc=16

It seems that it will not go higher as 128??
I have looked at the brownout reset but this doesn't help. My code can run for 1.5 hours and suddenly stall. It might have done 100 relay cycles without any problem.
About the Eeprom, at first this is a test. I might change the program in such a way that the eeprom routine only is called if any settings are changed. That would reduce the write cycles dramatically.
I will look at the datasheet for the ADC comment you gave.
Edit: solved the eeprom issue. |

possible problem....
you have #FUSES DEBUG enabled
depending on the programmer you're using, it might 'reconfigure' the 'fuses' to a setup that isn't what you want.
I do not use the 'ICD' and never 'DEBUG' so others can confirm this operation. It has been mentioned before on the forum....

I had noted this ages ago, but it didn't matter to me, since if using the watchdog, I'd always use a few mSec, rather than much longer times.
Agree wholeheartedly with temtronic, DEBUG _will_ cause some fuses to be changed unexpectedly.
The fuse list in the .lst file is always 'where to look' to see what is actually being programmed.
I must admit I'd change the whole approach rather, and have the code doing the main loop at speed, and delays being done using a counter in a timer (see the recent thread about long times), and a similar timer for the watchdog. Then have 'status' events, which when they happen advance the count used for the watchdog interval, by a few hundred mSec. |

Ttelmah, were can I find the information you showed? I found it under "C/ ASM List" which gives me a *.lst file. But your code layout seems different then mine.
I have replaced the debug for nodebug.
Your last comment I can not completely follow (perhaps because English is not my native language, and programming is quite hard for me).
If I understood correct you would the change the program. Mainly the for loops which are responsible for "reading" the switches (Enter, Op, Neer)?
@Jay, thanks for the tip, I replaced it as mentioned above. |

The actual output fuses display right at the bottom of the file.
The input fuses display right at the top.
So I cut the several hundred lines between these. |

Are you guys sure about this ? I installed vs. 5.018 and compiled a
simple program with the fuses shown in the first post, and I got this in
the .LST file. It's showing WDT32768.

More strange things happen. I changed the oscillator from HS to INTRC but in the LST file nothing changes after compiling and rebuilding the project.
The time stamp at the top of the LST file does change. |

I'd change to NODEBUG and see what happens...
also HOW are you programming the PIC? What device/software gets the code into the PIC? THAT software could be changing 'stuff' !!

| Un-install the compiler. Then re-install it and let it use the default paths. |

Jay, I did change the program as you described. I'm programming the PIC via CCSload and a ICD-U64.
@PCM, will give it a try. |
